The present disclosure relates to cooling and ventilation 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 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 fresh air cooling and ventilating, fresh air cooling, fresh air ventilating, or fresh air 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. The fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 fresh air cooling and ventilating system can determine the temperature of the interior and/or exterior of the building structure and other parameters such as humidity. The fresh air cooling and ventilating system can use these input parameters to control activation of a whole house fan system and/or air conditioning system. The fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 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 via cloud services. The controller(s) can determine when conditions permit for operation of the whole house fan system or the air conditioning system. For example, the fresh air cooling and ventilating 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 fresh air cooling and ventilating system can allow the air conditioning system to operate. The fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 fresh air cooling and ventilating system can be operated in a semi-automatic mode, which may prompt the user for certain input before, during, and/or after operation. The fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 or a web application connected to the fresh air cooing 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 or web application can display information about the fresh air cooling and ventilating system to the user.

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 fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 fresh air cooling and ventilating 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 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, 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 (

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 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.
In some embodiments, the fresh air controller 300 can be in two-way communication with a whole house fan controller 200. The connection between the fresh air controller 300 and the whole house fan controller 200 can be a wired or a wireless connection. In some embodiments, the fresh air controller 300 can be connected to the whole house fan controller 200 by an Ethernet cable connection or any other suitable wired connection. In some embodiments, the fresh air controller 300 can be connected to the whole house fan controller 200 by a Bluetooth connection, a Wi-Fi connection, and/or any other suitable wireless connection to send and receive communication signals.
The whole house fan controller 200 can receive a signal from the fresh air controller 300 as well as send a signal to the fresh air controller 300. The fresh air controller 300 can send an operate command signal or cease operation command signal to the whole house fan controller 200.

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, web application 236, smart home connection 208, 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 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, smart phone application, smart home connection, and/or web 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 216 or prompt sent via the smart phone application 220, the web application 236, smart home connection 208, 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, smart phone application 220, smart home connection 208, and/or web application 236, 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, 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, the web application 236, smart home connection 208, 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, the web application 236, smart home connection 208, 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 the smart home connections 208, including via the cloud services 204, as discussed herein.
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 216 to the smart phone application 220, via cloud service 204 and/or API connections 212, 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 216 to the smart phone application 220, via cloud service 204 and/or API connections 212, 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 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, the web application 236, smart home connection 208, 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, the web application 236, smart home connection 208, 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, the web application 236, smart home connections 208, 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, the web application 236, smart home connections 208, 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, the web application 236, smart home connection 208, 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, web application, smart home connection, 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.

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, smart phone application 220, smart home connection 208, and/or the web application 236.

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.

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, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above.

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 smart home connections 208, API connections 212, 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.

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 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 smart home connections 208, API connections 212, 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, smart phone application 220, smart home connection 208, and/or the web application 236.
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
