The present disclosure relates to multifunction adaptive whole house fan systems for building structures.
Heating and cooling the space in residential and commercial buildings accounts for a primary share of building energy consumption. Occupants or persons otherwise associated with building heating and cooling may either not know when it is optimum to use a heating and cooling system or otherwise not properly utilize the heating and cooling system. When one desires to have the whole house fan on, one opens one or more windows and manually turns on the switch. In order for whole house fan to work properly, at least one window needs to be open so as to allow the fan to pull sufficient outside air in to cool the dwelling.
When the outside ambient air temperature is lower than the internal air temperature, outside ambient air can instead be used to effectively cool the home or building structure, reducing the need to run a costly air conditioning system. Further, air conditioning systems merely circulate air located within a building structure, and do not bring any outside air, so any harmful environmental elements (e.g. dust, disease, chemicals) may remain within the building structure.
A whole house fan can be used to move air through the building structure when desired outside and/or inside conditions allow. Whole house fans include one or more high cubic feet per minute (cfm) fans, typically placed in the attic of a building structure, and function by creating a negative static pressure inside of the building structure to draw air in from the outside. The outside air is moved through the ceiling into the attic where the air is exhausted out through a vent by positive static pressure in the attic or upper floor. Louvered shutters can be placed over the vent to prevent cooled or heated air from escaping when the whole house fan is not in use. Whole house fan systems move large amounts of air and allow for the entire building structure air volume to be recycled with multiple air exchanges per hour, removing latent heat within the building structure. Advantageously, whole house fan systems typically require less energy than air conditioning systems and can reduce the need for air conditioning, therefore reducing energy consumption while providing a comfortable space for building occupants. The systems and methods disclosed herein provide a more efficient and cost effective cooling and ventilating of interior spaces of a building structure while improving the indoor or interior air quality.
In some embodiments, a multifunction adaptive whole house fan system disclosed herein may use open windows to serve as intake air vents. In some embodiments, the user may manually open the windows to allow for airflow into the building structure. In some embodiments, the multifunction adaptive whole house fan system disclosed herein may control one or more automated windows to allow for airflow into the building structure. The automated windows can be controlled by the system to be automatically opened by the system to drawn in air and be automatically closed by the system when the whole house fan is shut off.
The automated window can have one or more user control interfaces (e.g., buttons) for the user to open or close the automated window at the window itself (e.g., without system controls input). The automated window can further have security features to help warn when the automated window is forced open by, for example, activating one or more alarms. For example, the automated window can sense when the window is being forced open without user and/or system commands being provided to open (e.g., a burglar forcing the window open). When the automated window is forced open, the automated window can sound an alarm via a noisemaker of the automated window acting as an alarm system and/or trigger a general alarm system of the building structure. Further, the automated window can have a lock mechanism that can be activated by the system and/or user at the automated window using one or more user controller interface features (e.g., buttons) on the automated window to lock, close, engage, and/or secure the window in a desired or certain position and inhibit the automated window from being forced open.
The multifunction adaptive whole house fan system can control for and/or notify a user when a whole house fan may not be effective at cooling the building structure such as, for example, when the outside temperature is higher than the inside temperature. The multifunction adaptive whole house fan system may also be connected to a thermostat and an air conditioning system to avoid, for example, the air conditioning system running (being activated or operating) while the whole house fan is running (activated or operating), mitigating possible energy savings. The air conditioning systems discussed herein can include systems with a vapor compression refrigeration cycle.
In some embodiments, the multifunction adaptive whole house fan system can determine the temperature of the interior and/or exterior of the building structure and other parameters such as humidity. The multifunction adaptive whole house fan system can use these input parameters to control activation of a whole house fan system and/or air conditioning system. The multifunction adaptive whole house fan system can be connected to and at least partially control an air conditioning system. The fresh air cooling and ventilating system can be connected to an automated or automatic window system. The multifunction adaptive whole house fan system can control one or more automated window(s) to automatically open or close window(s) to, for example, serve as intake air vent(s) for the whole house fan system.
The multifunction adaptive whole house fan system can include one or more controller(s) that provides for automatic and/or manual control of certain parts of the system. The controller(s) can operate in various modes ranging from automatic operation of the system to substantially manual operation of the system. For example, in an automatic mode, the controller(s) can collect a variety of information from climate condition system(s) such as temperature sensors, humidity sensors, air quality sensors (such as for example sensors for detecting volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen), weather information, and/or other information via a variety of input sources, including sensors and the internet. The controller(s) can determine when conditions permit for operation of the whole house fan system or the air conditioning system. For example, the multifunction adaptive whole house fan system can turn off the air conditioning system and operate the whole house fan if it is cooler outside than in the interior space of the building structure. Alternatively, if it is hot outside, the multifunction adaptive whole house fan system can allow the air conditioning system to operate. The multifunction adaptive whole house fan system can also operate the whole house fan if there are undesired air pollutants (based on AQI levels) inside the building structure by bringing in fresh air from the outside.
Accordingly, the multifunction adaptive whole house fan system can be operated in a variety of modes. An automatic mode allows the system to operate with minimal or no user input after, for example, selection of the automatic mode. The multifunction adaptive whole house fan system can be operated in a semi-automatic mode, which may prompt the user for certain input before, during, and/or after operation. The multifunction adaptive whole house fan system can be operated in various selectable modes ranging from automatic to manual (including semi-automatic) depending on the user input for desired operation and/or devices, such as automated windows, connected to the fresh air cooling and ventilating system.
The multifunction adaptive whole house fan system can be controlled by the user utilizing a variety of methods. In some embodiments, one or more user devices are positioned within the building structure from which the user can control the system. The user device can display information about the fresh air cooling and ventilating system to the user. In some embodiments, the user can use a smart phone application connected to the multifunction adaptive whole house fan system over the internet or via a Bluetooth connection to control the fresh air cooling and ventilating system. Similar to the user device, the smart phone application can display information about the fresh air cooling and ventilating system to the user.

Methods of manufacturing the system(s) disclosed herein are included; the methods of manufacture can include providing, making, connecting, assembling, and/or installing any one or more of the features of the system(s) disclosed herein to achieve functions and/or features of the system(s) as discussed in this disclosure.
The Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of any subject matter described herein.
Embodiments of the present disclosure provide for a multifunction adaptive whole house fan system (e.g., fresh air cooling and ventilating fresh air cooling, fresh air ventilating, or fresh air system). The fresh air cooling and ventilating system can include a motorized whole house fan, a vent system, motorized automatic window(s), user device(s), connection(s) to thermostat(s) or other devices that control an air conditioning system, and/or controller(s) that control the fresh air cooling and ventilating system and/or air conditions system. The use of a multifunction adaptive whole house fan system in a building structure presents several advantages over the use of a traditional air conditioning system, including decreased energy usage and greater circulation of fresh ambient air, thereby reducing the amount of dust and contaminated air in the building structure.
In some embodiments, the multifunction adaptive whole house fan system can include motorized automatic window(s) (automatic window(s)), that can be connected to the one or more controllers. The one or more controllers can open and close the motorized automatic windows when the fresh air controller detects desired or predetermined conditions discussed herein. Automated window(s) can help increase utilization and ease of use of the fresh air cooling and ventilating system. For example, in order to run the whole house fan, a user may not need to manually open windows to allow for fresh air to be drawn into the building structure.
The one or more controllers can include a fresh air controller that can be connected to a whole house fan controller (motorized fan controller), which operates the whole house fan. The fresh air controller can also be connected to a thermostat controller of a thermostat. The thermostat controller can control an air conditioning system that can maintain a desired temperature inside the living/interior space of the building structure. In some embodiments, the fresh air controller and all associated controls, algorithms, and/or modes of the fresh air system as discussed herein can be incorporated into the thermostat as a separate controller in the thermostat or as thermostat controller itself. Accordingly, the controls, algorithms, and/or modes that are part of and/or executed by the fresh air controller can be part of and/or executed by the thermostat controller. For example, the controls, algorithms, and/or modes of the fresh air controller discussed herein can be part of the thermostat controller in new home/building installations, and/or an existing thermostat controller can be updated and/or upgraded with the controls, algorithms, and/or modes of the fresh air controller as discussed herein.
Coordination between utilization of the whole house fan system and the air conditioning system can mitigate running the whole house fan system when conditions are better for running an air conditioning system (for example, the outside temperature is hotter than the inside temperature) or running the air conditioning system when conditions are better for running the whole house fan system (for example, the inside temperature is hotter than the outside temperature). The fresh air controller can receive information via a connection to the internet in addition to receiving input from climate condition system(s) including temperature and other kinds of sensors both inside and outside of a building structure. In some embodiments, the fresh air controller can be connected to a ventilation fan, which can be positioned in the attic area of the building structure. The ventilation fan can help draw the exhaust of the whole house fan from the attic.
In some embodiments, the fresh air controller can receive data associated with an outside temperature value corresponding to ambient temperature around the building structure and an inside temperature value corresponding to temperature inside the living space. The fresh air controller can receive temperature data via temperature sensors connected to the fresh air controller. The temperature sensors can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, one or more temperature sensors maybe part of and/or positioned in a user device. In some embodiments, the fresh air controller can receive temperature data corresponding to an outside temperature value from an online source via a connection to the internet. In some embodiments, the fresh air controller can receive any temperature data discussed herein via a temperature sensor and/or the internet. The temperature sensors can be connected via any wired or wireless connection discussed herein.
In some embodiments, the fresh air controller can receive a humidity value corresponding to the humidity level inside the building structure and/or in the ambient air outside of the building structure. The fresh air controller can receive the humidity value either from a humidity sensor in wired or wireless connection with the fresh air controller or from an online source via a connection to the internet. The humidity sensor(s) can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, one or more humidity sensors maybe part of and/or positioned in a user device.
In some embodiments, the fresh air controller can receive an air quality value corresponding to the air quality level inside the building structure and/or in the ambient air outside of the building structure, including information about and/or levels of volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen. The fresh air controller can receive the air quality value either from an air quality (AQI) sensor in wired or wireless connection with the fresh air controller or from an online source via a connection to the internet. The AQI sensor(s) can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, one or more AQI sensors maybe part of and/or positioned in a user device. In some embodiments, one or more AQI sensors may standalone devices that are plugged into the electrical system or plug of a building structure. For example, carbon dioxide, carbon monoxide, and/or smoke detectors may be plugged into a plug of the building structure and connected (e.g., wirelessly) with the fresh air controller.
As used herein, humidity is used in its broad and ordinary sense and includes, for example, a measurement of the concentration of water vapor in the air. A relative humidity or humidity value as used herein falls between 0-100% (percent). High humidity in the interior air of a building structure can cause water damage to the interior of a building structure as well occupant discomfort. For these reasons, it can be advantageous to run the fresh air cooling and ventilating system when there ambient air outside the building structure is below a certain level of humidity.
In some embodiments, the fresh air controller can receive an air quality index data corresponding to the air quality index value in the ambient air outside of the building structure. As used herein, an air quality index is used in its broad and ordinary sense and includes, for example, a value that corresponds to the level of pollution in the air. For example, an air quality index can be utilized to convey the level of risk a person will encounter by breathing the ambient air. Air quality index is usually provided on a scale of 1-1000. Air quality index values in a range of 1-50 are considered excellent with no health implications. Air quality index values of 51-100 are considered good with only slight effects on individuals who are very sensitive to pollutants. Air quality index values between 101-150 are considered lightly polluted, and healthy people may experience slight irritation. Air quality index values between 151-200 are considered moderately polluted, and it is recommended the general population moderately reduce outside activity with those more at risk being advised to avoid outdoor activity. Air quality index values between 201-300 are considered heavily polluted, and the general population is advised to reduce outdoor activity. Air quality index values above 300 are considered severe pollution, and it is recommended that the general population should avoid outdoor activity.
In some embodiments, the fresh air controller can control the operation of the whole house fan and/or the air condition system based on a comparison between the inside and outside temperature values as well as comparing other data values including the outside temperature data, inside temperature data, attic temperature data, humidity data, and/or air quality index data.
The fresh air cooling and ventilating system disclosed herein can have the flexibility to be installed in several different building structure environments to provide an energy and cost savings. For example, the fresh air cooling and ventilating system can be installed in a building structure without an air conditioning system, retrofitted to be installed in a building structure with an existing air conditioning system, or installed as part of a new air conditioning system installation.
The user device 201 can include the fresh air controller 300 (

In some embodiments, the windows 110 shown in
The motorized automatic windows can open fully, close fully, or be positioned somewhere in between, for example, via a command signal from the fresh air controller 300. For example, in some embodiments, the motorized automatic window can open halfway between fully closed and fully open, a quarter way between fully open and fully closed, or three quarters of the way between fully closed and fully open. In some embodiments, the motorized automatic window can open vertically. In some embodiments, the motorized automatic window can open horizontally or by tilting away from its closed position in either the horizontal or the vertical direction or in any other suitable opening and closing motion.
The fresh air cooling and ventilating system 100 shown in
In some embodiments, the fresh air cooling and ventilating system 100 may use motorized automatic windows in combination with other types of devices such as dampers 111 installed on exterior walls of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment. In some embodiments, the fresh air cooling and ventilating system 100 may use other types of devices such as dampers 111 installed on exterior walls of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment.
In some embodiments, the dampers 111 can use or can have an air filter. In some embodiments, the dampers 111 do not use or do not have an air filter.

The fresh air cooling and ventilating system 100 shown in
In some embodiments, the fresh air cooling and ventilating system 100 may use motorized automatic windows in combination with other types of devices such as skylights 125 installed on the roof of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment. In some embodiments, the fresh air cooling and ventilating system 100 may use other types of devices such as skylights 125 installed on the roof of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment.
In some embodiments, skylights can be motorized automatic skylights that can be automatically opened and closed as discussed herein. In some embodiments, the motorized automatic skylights can function similar to automated windows as discussed herein.
In some embodiments, the skylights can be positioned in the roof of the building structure 106 such as in location depicted by vents 114. The vents 114 depicted in
In some embodiments, the skylight may be a natural tubular skylight 125 that has an air inlet 126 (e.g., a vent) to the ambient environment. When the WHF operates as discussed herein, the skylight, and in particular the air inlet 126 of the skylight, may function as an open window and/or damper as discussed herein to allow ambient air 107 into the interior space 108. When open, the vent of the skylight can permit the flow of ambient air 107 into the building structure 106 and when closed, can inhibit the flow of ambient air 107 into the building structure 106. The air inlet 126 may be motorized to open and close and function similarly to an automated window as discussed herein. When the air inlet 126 is in an open position, the negative static pressure can draw outside air 107 into the building structure 106 as the exhaust 124 from the WHF 102 is expelled into attic of the building structure with air being drawn and directed through the air inlet 126, the duct 127, and air outlet 128. Operating the WHF 102 can create a positive static air pressure in the attic space 104, which can expel air 120 out of the building structure 106 to the outside through vents 114 located in the attic space 104.
The skylight 125 may be mounted in the attic 104 and connected to an air outlet 128 in the ceiling or wall separating the attic space 104 from the interior space 108 to create a negative static pressure in the interior space 108. The air outlet 128 can be an opening that allows ambient light into the interior space 108. In some embodiments, the air outlet 128 can be a diffuser, a register, or any other similar device. The skylight 125 can have a duct 127 connecting the air inlet 126 to the air outlet 128. The duct may be a tubular structure or reflecting tube that reflects and/or directs ambient light into the interior space 108.
In some embodiments, the duct 119 depicted in
In some embodiments, the skylights 126 may be a window-type skylight installed in the roof of the building structure 106. When open, the skylight can permit the flow of ambient air into the building structure 106 and when closed, can inhibit the flow of ambient air into the building structure 106. The window-type of skylight may have a side that is pushed up/down or open to permit in ambient air into the interior space 108. The window-type of skylight may rotate on a hinge point to permit ambient air into the interior space 108. The window-type skylight may be motorized to open and close and function similarly to an automated window as discussed herein.
In some embodiments, the air inlet 126 in
Motorized automatic skylights and/or air inlets 126 can be in connection with a fresh air controller 300. The fresh air controller 300 can control the operation of the motorized automatic skylights and/or air inlets 126. In some embodiments, the fresh air controller 300 can send a command signal to close one or more or all of the automatic skylights and/or air inlets 126 in any of the operating modes or control logic flows discussed herein, including when sending a command signal to turn off the WHF 102 as discussed herein.
The motorized automatic skylights and/or air inlets 126 can open fully, close fully, or be positioned somewhere in between, for example, via a command signal from the fresh air controller 300. For example, in some embodiments, the motorized automatic skylights can open half way between fully closed and fully open, a quarter way between fully open and fully closed, or three quarters of the way between fully closed and fully open.
In some embodiments, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 6, 12, 15, or more skylights. Any number of the can be motorized automatic skylights. For example, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 5, or more motorized automatic skylights. In some embodiments, one or more of the skylights may be non-motorized and be opened by the user manually.
In some embodiments, the fresh air cooling and ventilating system 100 can include one or more ventilation fans 118 as shown in
The ventilation fan 118 can be in communication with a ventilation fan or attic fan controller 224 (see for example
In some embodiments, the WHF 102 as discussed herein can be installed in place of the ventilation fan 118. The air inlet 112 and the WHF 118 installed in a vent 114 can be connected by a flexible, sound insulating duct 119. The duct 119 is illustrated in dashed lines in
The fresh air cooling and ventilating system 100 can be installed in several different heating, ventilation, HVAC (heating, ventilation, and air conditioning) and/or air conditioning building environments/systems to provide an energy savings and cost savings. Air conditioning system or air conditioning as used herein may include one or more systems of a building structure used for heating, cooling, ventilating, and/or any other type of conditioning/thermal management and/or movement of air within and/or through the building structure. In some embodiments, the fresh air cooling and ventilating system 100 can be installed in a building structure 106 without an existing air conditioning system. In such an installation, the fresh air controller 300 can make control decisions on whether to activate the fresh air cooling and ventilating system 100 based on the external and internal building temperature and/or humidity conditions. If the user device 201 has received an input or is set for cooling, the fresh air controller 300 can determine whether the outside air temperature is cooler than the inside and turns on the WHF (including opening windows or dampers if included). If the outside temperature is warmer than the internal temperature, the fresh air controller 300 does not activate the system 100 but can continue to monitor the temperature and/or humidity parameters periodically until the outside temperature is cool enough to cool effectively.
In some embodiments, the fresh air cooling and ventilating system 100 can be installed in a home with an existing air conditioning system. In a home with existing air conditioning, the fresh air controller 300 can control the air conditioner as well as the fresh air cooling and ventilating system 100. In such an installation, the fresh air controller 300 can use signals received from the internal and external temperature, humidity, and/or AQI sensors 230 and/or information or signals received from the climate condition system(s) to make control decisions about whether to activate either the fresh air cooling and ventilating system 100 or the existing air conditioning. If the user device 201 has received an input or is set for cooling, the fresh air controller 300 first can consider whether the fresh air cooling and ventilating system has the capacity to efficiently cool the building structure 106. As discussed herein, the fresh air controller 300 can send a signal to activate the fresh air cooling and ventilating system 100 over the existing air conditioning whenever the ambient temperature and humidity conditions allow in order to realize a cost and energy savings over running the air conditioner. The fresh air controller 300 can be set to default to use the fresh air cooling and ventilating system 100 whenever possible instead of the air conditioning system to provide a cost savings. If the fresh air controller 300 determines that the fresh air cooling and ventilating system 100 can effectively cool the building structure, the fresh air controller 300 can send a signal to activate the fresh air cooling and ventilating system 100 until the desired temperature is reached. If, while the WHF 102 is running, the fresh air controller 300 determines that the WHF 102 is providing inadequate cooling and cannot cool the building structure 106 to the desired temperature, it can send a command/operation signal to the whole house fan controller 200 to turn off the WHF 102 and can turn on the air conditioner. The fresh air controller 300 then can continue to monitor the situation and can send a command/operation signal to the thermostat to turn off the air conditioner and send a command/operation signal to the whole house fan controller 200 to turn back on the WHFs 102 when conditions are optimal for the fresh air cooling and ventilating system 100.
In some embodiments, the fresh air cooling and ventilating system can be installed in a building as part of a new air conditioning installation. In such an installation, the user device 201 functions substantially the same as in installations retrofitted to function with existing air conditioning systems. The user device 201 may also fully control the operation of the air conditioning system, in particular when the system 100 installed as part of a new air conditioning installation.

For example, the window opener 130 can have one or more movement control buttons 150, 152 (or any other suitable interface mechanism) for moving the window opener 130 and moveable panel 134 as discussed herein. An up button 150 can be pressed by a user for the window opener 130 to move the moveable panel 134 up relative to the frame 136. A down button 152 can be pressed by a user for the window opener 130 to move the moveable panel 134 down relative to the frame 136.
The window opener 130 can have a lock control 154 (e.g., a button, a sliding protrusion, or any other suitable interface locking or lock mechanism), for example, on the window housing 148. The lock button 154 can be activated by a user to prevent the window from being opened to lock, close, engage, and/or secure the window in a desired or certain position and inhibit the automated window from being forced open. For example, if the automated window 110 is closed, the lock button 154 can be activated by the user for the window controller to lock the motor assemblies 144 to prevent the motors from rotating such that the moveable panel 130 is prevented from moving. For example, the one or more gears can resist movement against one or more teeth of the track 146 and thereby prevent movement of the moveable panel 134. In some embodiments, the lock button 154 can activate a physical lock that extends from the moveable panel 134 into a portion of the fixed panel 132 and/or the frame 136 to prevent movement of the moveable panel 134. In some embodiments, the system 100 can automatically activate the lock control 154 to inhibit the automated window from being opened. In some embodiments, the controller of the window opener 130 can automatically disengage the lock mechanism upon activation of the window opener by the system 100 as discussed herein or by activating any of the movement control buttons 150, 152.
In some embodiments, the window opener 130 can have or activate an alarm system when the moveable panel 134 is forced open (e.g., forced open by a person by not using the movement control buttons 150, 152 and/or commanded by the system 100 as discussed herein). The window opener 130 can be armed when the lock control 154 is activated by the user to prevent movement of the moveable panel 134. The window opener 130 can be armed by the system 100 and/or associated alarm system as discussed herein.
In some embodiments, the controller of the window opener 130 can be in communication (wirelessly or wired) with the alarm system of the building structure discussed herein. The alarm system can be triggered as discussed herein when the moveable panel 134 is forced open. The window opener can be activated or be armed at certain times of the day (e.g., during the night such as from 2100 to 0700). In some embodiments, the window opener 130 can have any suitable noisemaker such as a buzzer or a speaker. The noisemaker can be housed in the window housing 148.
In some embodiments, the controller of the window opener 130 can sense current to and/or voltage of the motor assemblies 144 as the moveable panel 134 moves along the tracks 146. The controller of the window opener 130 can learn, map, and/or store in memory specific values and variations in current to and/or voltage of the motor assemblies 144 as the motor assemblies 144 move along the tracks 144. The controller of the window opener 130 can compare the actual values of current to and/or voltage of the motor assemblies 144 along the tracks 146 to the stored current to and/or voltage of the motor assemblies 144 along the tracks 146. Upon detecting a variation, deviation, and/or change of the actual to the stored values of current to and/or voltage of the motor assemblies 144, for example, above a certain threshold, the controller of the window opener 130 can determine that either there is an obtrusion (e.g., a person's hand) or that someone is forcing the moveable panel 134 to trigger an alarm as discussed herein. In some embodiments, the controller of the window opener 130 can stop the movement of the moveable panel 134 to, for example, mitigate injury to a person (when the obtrusion is a body part of a person) as well as prevent damage to the motor assemblies 144 and/or any other components of the automated window 110.

The predetermined attic temperature, in some embodiments, can be 182 degrees Fahrenheit. A temperature of 182 degrees Fahrenheit or above may indicate that there is a fire in the building structure. In such a scenario the fresh air cooling and ventilating system 100 is designed to shut down to prevent air from being drawn into the building structure and further feeding any fire that may be occurring in the building structure. The predetermined attic temperature is not limited to 182 degrees Fahrenheit, but can be set at any temperature value, including 160, 165, 170, 170, and 180 degrees Fahrenheit. For example, under typical operating conditions, the attic temperature may reach between 120 and 140 degrees Fahrenheit.
For building structures positioned in excessively hot conditions, such as a desert, the attic temperature may reach up to 160 degrees Fahrenheit. In some embodiments, the smart phone application 220 and/or user device 201, can allow the user to modify the predetermined attic temperature, for example, depending on the location of the system 100. The system 100 may automatically modify the predetermined attic temperature depending on the location of the building structure within which the system 100 is installed. This feature is advantageous because it can prevent the system from exacerbating a fire that may be occurring in the building structure.
In some embodiments, as depicted in
In some embodiments, the predetermined operating parameters for air quality index value or predetermined air quality index value can be set by the user via the smart phone application 220 and/or user device 201. In some embodiments, the predetermined operating parameters for the air quality index can be set by the manufacturer, the installer, or some other entity during or prior to installation of the system 100. In some embodiments, the predetermined air quality index value can be 100. In some embodiments, the predetermined air quality index value can be 50, 60, 70, 80, 90, 110, 120, 130, 140, or 150. It is advantageous to check the air quality index value of the ambient air outside the building structure prior to operating the WHF because operating the WHF when the air quality index is high may cause highly polluted air to be pulled into the building structure, potentially negatively affecting its occupants.

In some embodiments, the fresh air controller 300 can compare the present or current outside temperature value to a predetermined ambient temperature operating parameter. In some embodiments, the predetermined ambient temperature operating parameter can be set by the user utilizing the user device and/or smart phone application, or by the manufacturer or the system of the person installing the system or any combination of the above.
In some embodiments, as depicted in
In some embodiments, as depicted in
In some embodiments, the fresh air controller 300 can compare the inside temperature value to the outside temperature value. If the fresh air controller determines that the outside temperature value is greater than the inside temperature value in step 755, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785. In some embodiments, as depicted in
In some embodiments, as depicted in
In some embodiments, the stored previous outside temperature value can correspond to the outside temperature received by the fresh air controller 300 during the most recent iteration of the WHF off control logic flow path 702. In some embodiments, the stored previous outside temperature value can correspond to the outside temperature received by the fresh air controller 300 during the most recent iteration of the WHF on control logic flow path 703. In some embodiments, change in temperature is not limited to 1 degree Fahrenheit and the fresh air controller 300 can determine whether the outsider temperature has increased by more than 2 degrees Fahrenheit, 3 degrees Fahrenheit, 5 degrees Fahrenheit, or any other temperature increase.
In some embodiments, if the fresh air controller 300 determines there has been an increase in the outside temperature of more than 1 degree Fahrenheit in step 765, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785. In some embodiments, the fresh air controller can delete or clear the stored previous temperature value in step 785. In some embodiments, as depicted in
In some embodiments, as depicted in
In some embodiments, the fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed based on the inside temperature value, as shown in step 775. The fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed as discussed herein.
In some embodiments, the fresh air controller 300 can compare the inside temperature value to a first, second, and third predetermined inside temperature values. For example, if the inside temperature value is between the first and second predetermined inside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the inside temperature value is between the second and third predetermined inside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a second speed. If the inside temperature value is greater than the third predetermined inside temperature value, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.
In some embodiments, the first, second, and third fan speeds correspond to a low, a medium, and a high speed respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the inside temperature of the building structure such that, for example, the number of speeds is equal to the number of predetermined temperature values.
In some embodiments, the first predetermined inside temperature to which the fresh air controller 300 can compare the inside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can send a command signal to turn off the WHF and close the automatic windows when the inside temperature value is lower than the lowest predetermined inside temperature value. In some embodiments, the first predetermined inside temperature can be the predetermined inside temperature value for WHF operation discussed herein with reference to step 760. In some embodiments, the predetermined inside temperature values to which the inside temperature is compared to can be set by the user utilizing the user device and/or smart phone application, or by the manufacturer or the system of the person installing the system or any combination of the above. This can help to not turn on, activate, or keep running the WHF if the building structure is already cooler than the user would like it to be.
In some embodiments, when the fresh air controller 300 determines that the WHF 102 should be turned off while progressing through the WHF on logic flow path 703, the fresh air controller 300 can delete or clear the store outside temperature value as part of step 785. In some embodiments, as part of step 785 for any of the logic steps discussed herein, the fresh air controller 300 can send a signal to the home thermostat to resume or continue operation of the air conditioning system when it is not ideal to run the WHF.
In some embodiments, when the fresh air controller 300 sends a signal to close the automatic windows, as shown in step 785, the fresh air controller 300 can perform a check to determine or verify whether the automatic windows have been closed. The fresh air controller 300 can perform this check by determining the number of automatic windows connected to the fresh air controller 300 or the system 100. The fresh air controller 300 can retrieve or receive a status signal from each window indicating whether or not the any of the particular window(s) are open. If one or more of the windows are open, the fresh air controller 300 can send a command signal to close the corresponding window. If all of the windows are closed, the WHF on control logic flow path 703 can be complete. If the fresh air controller 300 receives a signal indicating there is an error with one or more windows that cannot be closed automatically, the fresh air controller 300 can cause an error notification to be sent to the user through a push notification or prompt sent via the smart phone application 220, and/or the user device 201 indicating that one or more particular windows could not closed automatically. If there is more than one automatic window connected to the system, the fresh air controller 300 can repeat the same steps for each automatic window.
In some embodiments, the when the automatic mode is turned off manually from either the switch 432, the user device 201, and/or smart phone application 220, the fresh air controller 300 can clear the stored outside temperature value, send a command signal to close the automatic windows, and verify the automatic windows are closed as discussed herein.

In some embodiments, as depicted in
In some embodiments, as depicted in
In some embodiments, as depicted in
In some embodiments, to verify or check that at least one automatic window is open in step 780, the fresh air controller 300 can determine the number of automatic windows connected to the fresh air controller 300 or the system 100. The fresh air controller 300 can determine whether the first automatic window is set to automatically open. If the first automatic window is set to automatically open, the fresh air controller 300 can send a signal to open the first automatic window. The fresh air controller 300 can request the status of the first automatic window and can receive a signal indicating whether the first automatic window is open, closed, or is experiencing an error. If first automatic window is closed or experiencing an error, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220 and/or the user device 201, alerting the user of the error and turn off or exit automatic mode. If there are multiple or one or more automatic windows, the fresh air controller 300 can repeat this process for each automatic window and can activate the WHF if at least one automatic window is open. If all of the automatic windows are closed or experiencing an error, the fresh air controller 300 can turn off or exit automatic mode, while having sent a push notification or prompt, via the smart phone application 220 or the user device 201, alerting the user of the error based on the closed or error automatic window logic as discussed herein. In some embodiments, if the fresh air controller 300 verifies at least one window is open in step 780, the fresh air controller 300 can send a signal to the whole house fan controller 200 turn on, activate, or operate the WHF and adjust the WHF speed, as shown in step 790.
In some embodiments, the system 100 can be communication with an alarm system of the building structure. The alarm system of the building structure can be designed to monitor the building structure and inform when an intruder has entered the building structure or some other undesirable event has occurred when the alarm system is active or activated (e.g., armed). The fresh air controller 300 can send and receive communication signals to and from the alarm system. In some embodiments, the fresh air controller 300 can be in communication with the alarm system or a controller of the alarm system through smart home connections, including via cloud services.
In some embodiments, when the alarm system is active, the alarm system or alarm system controller can send a communication or status signal to the fresh air controller 300 indicating that alarm system is active and that the one or more automatic windows of the building structure should not be opened. In some embodiments, when the alarm system is active and the user controls the system 100 to operate and open the one or more automatic windows as discussed herein (e.g., in the semi-automatic mode(s)), the fresh air controller 300 can send a push notification to the smart phone application 220, via the internet, alerting the user that the alarm system is active and that the one or more automatic windows should not be open or that opening the one more automatic windows may trigger the alarm system. In some embodiments, when the alarm system is active and the system 100 is automatically operating (e.g., in the automatic mode(s)) where one or more automatic windows are to be automatically opened as discussed herein, the fresh air controller 300 can send a push notification to the smart phone application 220, via the internet, alerting the user that the alarm system is active and that the one or more automatic windows could not be opened or that opening the one more automatic windows may trigger the alarm system.
The system 100 may configured such that the user may override the functionality or setting of automatic windows not being able to be opened when the alarm system is active to have automatic windows be opened by the fresh air controller 300 even if the alarm system is active. The fresh air controller 300 may send a status signal to the alarm system indicating user override for opening automatic windows. In some embodiments, the alarm system may include functionality (e.g., with the fresh air controller 300 sending an override signal) to allow the fresh air controller 300 to open one or more automatic windows without triggering the alarm system while the alarm system is active.
In some embodiments, when the alarm system is active, the fresh air controller 300 can suspend operation of the WHF and not open the one or more windows in one or more modes discussed herein that cause the automatic windows to automatically open (e.g., in the automatic mode(s)) where the fresh air controller 300 monitors certain parameters whether to automatically open one or more automatic windows and turn on the WHF. In some embodiments, when the alarm system is inactive or deactivated (e.g., disarmed), the alarm system or alarm system controller can send a communication or status signal to the fresh air controller 300 indicating that alarm system is inactive and that the one or more automatic windows of the building structures can be opened for, for example, the system 100 to operate as discussed herein. When the alarm system is activated, the alarm system can send an active status signal to the fresh air controller 300; if the WHF is operating with one or more automatic windows open (in any mode), the fresh air controller 300 may in response suspend operation of the WHF and close one or more automatic windows as discussed herein to, for example, secure the building structure 106.
In some embodiments, the fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed based on the inside temperature value, as shown in step 790. The fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed as discussed herein in reference to step 775.
In some embodiments, after turning on the WHF according to the WHF off logic flow path 702 discussed herein, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside temperature value received by the fresh air controller 300 during this iteration of the flow path 702, such as at step 740 as discussed herein or after performing step 790 with the WHF operating. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.

In some embodiments, the predetermined amount of time for operation of the WHF can be 30 minutes. In some embodiments, the predetermined amount of time for operation can be 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, or greater than 60 minutes.
As depicted in
In some embodiments, the when the semi-automatic mode is turned off manually by the user from the smart phone application 220 and/or the user device 201, the fresh air controller 300 can clear the stored outside temperature value, send a signal to close the automatic windows, and verify the windows are closed as discussed herein.
In some embodiments, as depicted in
In some embodiments, a push notification or prompt that does not turn off the WHF or prevent the system from operating can be added, in some embodiments, at any decision point of the fresh air controller 300 whether in the WHF on flow path or the WHF off flow path, or any other logic flow path utilized by the fresh air controller 300. For example, in some embodiments, when the WHF is on or when the WHF is off, the fresh air controller 300 may send a push notification or prompt, via the smart phone application 220 and/or the user device 201, alerting the user that the outside humidity is high and that it is not preferable to operate the WHF, but nonetheless, still allow the user to continue operation of the WHF.
Returning to the WHF off logic flow path 802, in some embodiments, the fresh air controller 300 can allow the user to set whether the user wants the automatic windows to be automatically opened. As depicted in
If the automatic windows are set to open automatically in step 850, as depicted in
In some embodiments, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside temperature value received by the fresh air controller 300 during the current iteration of the logic flow path after completing the WHF on logic flow path 802 and determining that the WHF should be turned on according to step 870. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.
In some embodiments, the fresh air controller 300 can delete or clear the stored outside temperature value if, during the WHF on logic flow path 803, the fresh air controller 300 determines the WHF should be turned off according to step 845.

For the WHF off flow path 902, in some embodiments, as depicted in
After performing step 930 as discussed herein, for example, in reference to step 760, in some embodiments, the fresh air control 300 can determine in step 940 whether the automatic windows are set to automatically open on the WHF off flow path 902. If the windows are not set to automatically open, the fresh air controller 300 can send a prompt or push notification, via the smart phone application 220 and/or the user device 201 as discussed herein, to the user as shown in step 942. The prompt or push notification can query the user whether the user would like to open the automatic windows manually or automatically, as shown in step 942.
If the user indicates or provides a user input that the user would like to open the windows manually, the fresh air controller 300 can send a prompt or push notification, via the smart phone application 220 and/or the user device 201, to the user asking whether one or more windows are open, as shown in step 954. If the user indicates there is a window open, in some embodiments, the fresh air controller 300 can send a command signal to cause the WHF to turn on and adjust the WHF speed based on the temperature inside the house as discussed herein (for example at various speeds based on the inside temperature value as discussed herein for step 790), as shown in step 960. If the user indicates that there is not a window open, the fresh air controller 300 may not send a command signal to turn on the WHF, as shown in step 962.
In some embodiments, if in response to the query of step 942, the user indicates they would like to open the windows automatically, the fresh air controller, as part of step 944, can determine or receive one or more signals indicating the number of automatic windows 228A-C connected to the fresh air controller 300. If the fresh air controller 300 determines or receives a signal indicating that one automatic window 228A-C is connected the system 100 or otherwise operational, the fresh air controller 300 can proceed to step 950 as discussed herein (for example, as discussed herein for performing step 780).
If the fresh air controller 300 receives a signal indicating two or more (more than) one automatic windows 228A-C are connected to the system 100 or otherwise operational, the fresh air controller 300, as part of step 946, can cause a prompt or user notification that iterates through the two or more automatic windows to ask the user for each particular automatic window if the user would like to have that particular automatic window open automatically. For example, the fresh air controller 300 can send a signal to cause a prompt for user to indicate if the user would like to open automatic window 228A, if the user would like to open automatic window 228B, and/or if the user would like to open automatic window 228C. If the user indicates that at least one of the automatic windows is to be opened automatically, the fresh air controller 300 sends a command signal to cause to open the particular (one or more) automatic window selected to be automatically opened and verifies that the particular (one or more) automatic window is open. After verification that the particular (one or more) window is open, the fresh air controller 300 can proceed to step 960 as discussed herein.
If the particular (one or more) window selected to be automatically opened is not verified to be open, the fresh air controller 300 can cause a prompt or user notification, via for example smart phone application, indicating there was a problem opening the particular (one or more) window. If none of the automatic windows are verified to be open, the fresh air controller 300 can proceed to step 952 and cause a prompt or user notification asking the user if the user would like to run the WHF without automatic windows according to step 952 as discussed herein, proceeding to step 954 or step 962 depending the user's input as discussed herein.
If the user indicates that none of the one or more automatic windows 228A-C are to be opened automatically in response to the iterative query of step 946, the fresh air controller 300 can cause a prompt or user notification, via for example the smart phone application, indicating that no windows were selected to be open and asking the user to manually open one or more windows in the building structure. The fresh air controller 300 can proceed to step 954 and cause a prompt or user notification asking the user if there is a window open in the building structure according to step 954 as discussed herein, proceeding to step 960 or step 962 depending the user's input as discussed herein.
Returning to step 940, if at step 940 the fresh air controller 300 determines that the automatic windows are set to operate automatically, the fresh air controller 300 can proceed to the step 950 of the WHF off logic flow path 902. At step 950, the fresh air controller 300 can send a command signal to cause the automatic windows to open and verify at least one automatic window is open as discussed herein. If the fresh air controller 300 determines that at least one automatic window is open in step 950, in some embodiments, as depicted in
If the fresh air controller 300 determines that at least one automatic window is not open in step 950, in some embodiments, as depicted in
If the user's answer or input to the query of step 952 indicates that user would not like to run the WHF without automatic windows, the fresh air controller 300 can cause a push notification or prompt informing the user there is an issue with one or more automatic windows and to diagnose the settings or issues for the one or more automatic windows. If the user's answer the query of step 952 indicates the user would like to run the WHF without automatic windows, the fresh air controller 300 can cause a push notification or prompt asking the user if there is an open window in the building structure, as shown in step 954, via the smart phone application 220 and/or the user device 201. The window that is open according to step 954 can be an automatic window 228A-C as discussed herein or any other manual or traditional window in the building structure. The fresh air controller 300 can receive information indicating the user's answer or input to the question of query in step 954 provided by the user through either the smart phone application and/or user device. If the user indicates at least one window is open in the building structure, the fresh air controller 300 can send a command signal to cause the WHF to turn on and adjust the WHF's speed according to the inside temperature of the building structure as discussed herein, as shown in step 960. If the user indicates there is not at least one window open in the building structure, the fresh air controller 300 will not turn on the WHF, as shown in step 962, and can cause a push notification or prompt through either the smart phone application 220 and/or the user device 201 that the WHF will not turn on because there are no windows open.
In some embodiments, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside ambient temperature value received by the fresh air controller 300 during the current iteration of the logic flow path after completing the WHF off logic flow path 902 and determining that the WHF should be turned on according to step 960 discussed herein. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.
In some embodiments, the fresh air controller 300 can delete or clear the stored outside temperature value if, during the WHF on logic flow path 903, the fresh air controller 300 determines the WHF should be turned off according to step 945 discussed herein.

For step 1024, if the fresh air controller determines the inside temperature is less than a predetermined value and is already cool enough, the fresh air controller 300 may proceed to step 1040 and will not turn on the WHF. If the fresh air controller 300 determines that the inside temperature is greater than the predetermined value, the fresh air controller 300 can proceed to step 1030 and adjust the WHF speed based on the inside temperature.
In some embodiments, the fresh air controller 300 can determine whether to turn the WHF on based on the first predetermined inside temperature as discussed herein. For example, the first predetermined inside temperature to which the fresh air controller 300 can compare the inside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can proceed to step 1040 to not turn on the WHF when the inside temperature value is lower than the lowest predetermined inside temperature value. In some embodiments, the fresh air controller 300 can proceed to step 1030 to turn on the WHF and adjust the speed based on the inside temperature as discussed herein when the inside temperature value is greater than the lowest predetermined inside temperature value. In some embodiments, the first predetermined inside temperature can be the predetermined inside temperature value for WHF operation discussed herein with reference to step 760. In some embodiments, the predetermined inside temperature values to which the inside temperature is compared to can be set by the user utilizing the user device and/or smart phone application, or by the manufacturer or the system of the person installing the system or any combination of the above.

In some embodiments, after turning on the system 100 and adjusting the WHF speed after completing an iteration of the WHF off logic path 1102, the fresh air controller 300 can store the stored outside temperature value corresponding to the outside temperature the fresh air controller received during the iteration of the WHF off logic path 1102.
In some embodiments, when semi-automatic mode is turned off manually either from the user device 201, switch 432, and/or smart phone application 220, the fresh air controller 300 can delete or clear the stored outside temperature value.
Steps 1201, 1210, 1220, 1230, 1240, 1250, and 1260 of
As depicted in
If at any of steps 1210, 1220, 1230, and 1240, the fresh air controller 300 determines that the parameter is not within the operating parameters or if the fresh air controller 300 determines that the inside temperature is not higher than the outside temperature as shown in step 1250 or if the fresh air controller determines the inside temperature is below a predetermined temperature as shown in step 1260, the fresh air controller 300 can cancel the control logic, as shown in step 1202 and a push notification or prompt will not be sent to possibly operate the WHF or system. The fresh air controller 300 will also cancel the control logic if the fresh air controller 300 determines the WHF 102 is already running or operating as shown in step 1201.
The control logic and function of
In some embodiments, steps 1201, 1210, 1220, 1230, 1240, 1250 and 1260 can be reordered or removed. The fresh air controller 300 can operate the push notification or prompt control logic in a variety of different configurations performing only a select number of the steps shown in
As described above, attic ventilation fans 118 can facilitation the expulsion of air 120 from the attic space. While the motorized fan or whole house fan 102 can expel air out of the attic space, the addition of ventilation fans 118 can increase the efficiency with which air is pushed out of the attic space thus allowing air from the living or interior space to be more easily pulled into the attic by the WHF 102. In some embodiments, there can be one ventilation fan or there can be multiple (one or more ventilation fans).
In some embodiments, the user can select whether or not the ventilation fan(s) 118 is utilized by the fresh air system 100 using the switch 432, user device 201, and/or smart phone application 220.
In some embodiments, as depicted in
In some embodiments, as depicted in
As depicted in
The speed at which the ventilation fan operates can correspond to a speed selected by the user or one set by either the manufacturer or the installer of the fresh air cooling and ventilating system 100. Alternatively, the fresh air controller 300 can send a command/operation signal causing the ventilation fan controller 224 to operate the ventilation fan 118 at different speeds. For example, in some embodiments the ventilation fan controller 224 or ventilation fan 118 can operate at different speeds depending on the speed of the WHF 102. Alternatively, in some embodiments, the ventilation fan 118 can operate at different speeds depending on other variable or parameters discussed herein such as outside temperature and/or inside temperature.
In some embodiments, as depicted in
In determining whether or not the parameters are within operating conditions, as depicted in step 1402, the fresh air controller 300 can receive values corresponding conditions inside and outside the building structure and compare them to operating parameters as discussed herein. For example, the fresh air controller 300 can determine whether the attic temperature, Air Quality Index, outside humidity, current outside temperature, and inside temperature are all within operating parameters in the same manner as steps 710, 720, 730, 740, and 760, respectively of

After sending a signal or command to turn on the WHF 102, the fresh air controller can proceed to step 1416 and adjust the WHF speed based on the temperature inside the building structure and/or the temperature outside the building structure. The adjustment of the WHF speed as depicted is step 1416 can correspond to step 775 of
In some embodiments, the adjustment of the WHF speed depicted in step 1416 can be based on the temperature outside the building structure. Where the fresh air controller 300 adjusts the WHF speed based on the temperature outside the building structure, the fresh air controller 300 can compare the inside temperature value to a first, second, and third predetermined outside temperature values. For example, if the outside temperature value is between the first and second predetermined outside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the outside temperature value is between the second and third predetermined outside temperature values, the fresh air controller 300 can send a command signal to operate WHF 102 at a second speed. If the outside temperature value is greater than the third predetermined outside temperature value, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.
In some embodiments, the first, second, and third WHF speeds correspond to a low, a medium, and a high speed, respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the outside temperature of the building structure such that, for example, the number of speeds is equal to the number of predetermined temperature values.
In some embodiments, the first predetermined outside temperature to which the fresh air controller 300 can compare the outside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can send a command signal to turn off the WHF and close the automatic windows when the outside temperature value is lower than the lowest predetermined outside temperature value. In some embodiments, the predetermined outside temperature values to which the outside temperature is compared to can be set by the user utilizing the user device and/or smart phone application, or by the manufacturer or the system of the person installing the system or any combination of the above. This can help to not turn on, activate, or keep running the WHF if the building structure is already cooler than the user would like it to be.

The predetermined minimum inside temperature value can correspond to the first predetermined temperature as discussed herein for inside temperatures. Where the inside temperature is less than the predetermined minimum inside temperature value, the fresh air controller 300 can send a signal or command to turn off the WHF 102. The predetermined minimum inside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, and/or smart phone application 220.
In some embodiments, step 1420 can correspond to steps 745, 755, and 765 of
Where the fresh air controller 300 determines the WHF 102 should not be turned off at step 1420, the fresh air controller can iteratively repeat steps 1416 and 1420 until the fresh air controller 300 determines the WHF 102 should be turned off, as depicted in step 1414, or the user manually turns off the WHF as depicted in step 1422. The user can turn off the WHF utilizing the use the switch 432, user device 201, smart phone application 220.

After or at the same time as sending a signal or command turning off the WHF 102 as depicted in step 1428, the fresh air controller can optionally perform steps 1424 and/or 1432 (as depicted by dashed lines in
In some embodiments, as depicted in
After sending a signal or command to open the automatic windows as depicted in step 1504, the fresh air controller 300 can send a signal or command to cause to turn on the WHF 102 as depicted in step 1508. The system will then wait for further input from either a timer set by the user or from manual input by the user.
In some embodiments, the user can utilize the switch 432, user device 201, and/or smart phone application 220 to set a timer such that the fresh air controller 300 turns off the system after a set amount of time as depicted in step 1510. In some embodiments, as depicted in
After sending a signal or command to turn off the WHF 102, the fresh air controller can send a signal or command to close the one or more automatic window connected to the system 100 as depicted in step 1520. Step 1520 can correspond to step 785 of
In some embodiments, the fresh air controller 300 can adjust the WHF speed based operation or operational time of the WHF 102. The operation time can correspond to how long the WHF 102 has been working whether turned on by a user or automatically activated in any of the modes discussed herein. The fresh air controller 300 can track an operation time of the WHF 102 operating or receive time data associated with the operation time of the WHF 102 operating. For example, the fresh air controller 300 can have a clock or timer module that keeps track of how long the WHF 102 has been operating. The fresh air controller 300 can receive time data associated with time via internet services and determine operation time based on the time data.
With the fresh air controller 300 adjusting the WHF speed based on the operation time, the fresh air controller 300 can compare the operation time or a value corresponding to the operation time of the WHF 102 to a first, second, and third predetermined time values. For example, if the operation time is less than the first predetermined time, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the operation time value is between the first and second predetermined time values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a second speed. If the operation time value is between the second and third predetermined operation time values, the fresh air controller 300 can send a command signal to operate WHF 102 at a third speed.

In some embodiments, the fresh air controller 300 can perform step 1608, step 1612, or both step 1608 and step 1612 in addition to step 1616. The dashed lines linking steps 1608 and 1612 to the rest of the control logic diagram depicted in
After opening the one or more automatic windows 228A-C connected to the system in step 1616 and, in some embodiments, performing steps 1608 and 1612, the fresh air controller can proceed to determine whether to turn off the WHF based the temperature inside the building structure and/or outside the building structure as depicted in step 1620. Step 1620 can correspond to step 1420 of
Where the fresh air controller determines the WHF 102 should not be turned off at step 1620, the fresh air controller can iteratively repeat step 1620 until the fresh air controller 300 determines the WHF 102 should be turned off. Where the control logic of
In some embodiments, the fresh air controller 300 can perform step 1626 in addition to step 1620. The dashed lines linking steps 1626 to the rest of the control logic diagram depicted in
If the fresh air controller 300 determines the WHF 102 should be turned off based on the temperature inside and/or outside the building structure in step 1620 and/or based on the air quality index in step 1626, the fresh air controller 300 can send a signal or command turning off the WHF 102 as depicted in step 1624. After sending a signal or command to turn off the WHF 102, the fresh air controller 300 can send a signal or command to close the one or more automatic windows. In addition to performing step 1628, the fresh air controller 300, after sending a signal or command to turn of the WHF 102 in step 1624, can send signal or command to turn on a thermostat connected to the system 100 as depicted in step 1632 thereby allowing climate of the building structure to be conditioned by an air conditioning system instead of the fresh air system 100 when conditions are not optimal for the WHF operation. The dashed lines linking step 1632 to the rest of the control logic diagram depicted in
The fresh air controller 300 can monitor the AQI values, information, and/or signals that are received from climate condition systems 217, internet, and/or sensors 230 as discussed herein. At step 1701, the fresh air controller 300 can determine whether AQI values inside the building structure are greater than the desired or predetermined threshold or range (e.g., beyond or outside of a desired condition or predetermined range). For example, one or more sensors 230 can monitor whether volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen in the building structure 106 (including attic space 104 and/or interior space 108) exceed or are greater than the desired levels or predetermined thresholds. Upon determining that the one or more AQI values exceed the predetermined levels, the fresh air controller 300 can send a push notification 216 at step 1702 to the user as discussed herein to alert the user that of the AQI value and associated information about the AQI level being greater than the predetermined levels, and/or the fresh air controller 300 can turn on the WHF as discussed herein to remove the undesired air pollutants inside the building structure (e.g., when AQI levels are high or above predetermined thresholds) by bringing in fresh air. The predetermined thresholds for AQI can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.
In some embodiments, the fresh controller 300 can be programmed to not monitor or send command signals in response to carbon dioxide levels. High or undesirable carbon dioxide levels may indicate a fire inside the building structure. Turning on the WHF may further fuel and expand the fire. Accordingly, it may be undesirable to have the fresh air controller turn on WHF. In some embodiments, however, the fresh air controller 300 can monitor carbon dioxide levels inside the building structure. When carbon dioxide levels are above a predetermined range or threshold, the fresh air controller 300 can turn off the WHF for safety in case a fire is present inside the building structure and/or send a push notification 216 to the user alerting the user of the carbon dioxide levels exceeding a predetermined threshold.
In some embodiments, as part of step 1701, the fresh air controller 300 can compare inside AQI values to outside AQI values to determine whether to turn on the WHF. For example, even when inside AQI values our greater than the predetermined levels, if outside AQI values are greater by a larger amount or value of the predetermined levels, the fresh air controller 300 can determine to not turn on the WHF and/or not send a push notification 216 to the user regarding the AQI levels. The fresh air controller can determine and compare inside to outside AQI values using signal and value inputs from the climate condition system 217, air conditioning system 215, and/or one or more sensors 230 as discussed herein.

As part of proceeding to step 1704, the fresh air controller can optionally perform step 1708 to open and/or verify one or more windows are open, for example, prior to proceeding to step 1704. The dashed lines linking steps 1708 to the rest of the control logic diagram depicted in
After sending a signal or command to turn on the WHF 102, the fresh air controller can optionally perform step 1712, for example, prior to proceeding to step 1720. The dashed lines linking step 1712 to the rest of the control logic diagram depicted in
After sending a signal or command to turn on the WHF 102, the fresh air controller can optionally proceed to step 1716 (as depicted by dashed lines
In some embodiments, the adjustment of the WHF speed depicted in step 1716 can be based on the AQI values inside and/or outside the building structure. Where the fresh air controller 300 adjusts the WHF speed based on the AQI values inside the building structure, the fresh air controller 300 can compare the AQI values to a first, second, and third predetermined AQI values. For example, if the AQI values is between a first and second predetermined AQI values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the AQI value is between a second and third predetermined AQI values, the fresh air controller 300 can send a command signal to operate WHF 102 at a second speed. If the AQI value is greater than the third predetermined AQI values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.
In some embodiments, the first, second, and third WHF speeds correspond to a low, a medium, and a high speed, respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the AQI values inside the building structure such that, for example, the number of speeds is equal to the number of predetermined AQI values.
In some embodiments, the fresh air controller 300 can proceed to step 1720 directly after step 1704. In some embodiments, the fresh air controller can optionally perform steps 1712 and/or 1716 as discussed herein. In step 1720, the fresh air controller can determine whether to turn off the WHF 102 based on the inside AQI values of the building structure and/or the outside AQI of the building structure. In order to determine whether to turn off the WHF 102 the fresh air controller can receive a value corresponding to the present air AQI. The fresh air controller can also store a value corresponding to the air AQI at a previous time. For example, the previous time could be the time at which a previous iteration of the control logic was run or the outside AQI at the time the WHF 102 was turned on.
The fresh air controller 300 can monitor the AQI values, information, and/or signals that are received from the internet, climate condition systems 217, and/or sensors 230 as discussed herein. At step 1720, the fresh air controller 300 can determine whether inside and/or outside AQI values are less than the desired or predetermined threshold or range (e.g., beyond a desired condition or predetermined range) as discussed herein for step 1701, but upon determining that the inside and/or outside AQI values are within desired ranges, the fresh air controller 300 can send a push notification to the user and/or turn off the WHF.
For example, the fresh air controller 300 can determine whether AQI values inside the building structure are less than the desired or predetermined threshold or range (e.g., within a desired condition or predetermined range). One or more sensors 230 can monitor whether volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen in the building structure 106 (including attic space 104 and/or interior space 108) are within or less than the desired levels or predetermined thresholds. Upon determining that the AQI values within the predetermined levels, the fresh air controller 300 can send a push notification 216 at step 1721 to the user as discussed herein regarding the AQI value and associated information alerting the user that the AQI levels are within the predetermined levels and/or the fresh air controller 300 can turn off the WHF as discussed herein.
In some embodiments, as depicted in
In the automatic or semi-automatic mode, where the fresh air controller 300 determines the WHF 102 should not be turned off at step 1720, the fresh air controller can iteratively repeat steps 1720 until the fresh air controller 300 determines the WHF 102 should be turned off, as depicted in step 1714, or the user manually turns off the WHF as depicted in step 1722. The user can manually turn off the WHF utilizing the use the switch 432, user device 201, and/or smart phone application 220.
Where the fresh air controller 300 determines the WHF 102 should be turned off (and in some embodiments, where the user manually turns off the WHF), the fresh air controller 300 can send a signal or command turning off the WHF 102. After or at the same time as sending a signal or command turning off the WHF 102 as depicted in step 1728, the fresh air controller can optionally perform steps 1724 and/or 1732 (as depicted by dashed lines
