The present invention relates to the field of air conditioning and, more specifically, to the field of using a naturally-occurring water temperature difference to condition air, and associated systems and methods.
Air conditioning systems are pervasive throughout industrialized nations for providing cooling to enclosed interior areas. Traditional cooling systems utilize refrigeration cycles requiring significant expenditure of electrical power, driving down the efficiency of such systems. Moreover, systems relying on such refrigeration cycles are expensive to produce and maintain, and often include the use of materials that are environmentally unfriendly and must be carefully isolated from the environment.
The use of natural sources of cool water in cooling systems has been demonstrated in U.S. Pat. No. 2,299,335 to McGrath, using well water in a cooling system. However, the disclosure of McGrath requires the use of a compressor in conjunction with the well water, which then runs through a coding coil. The use of the compressor reduces the energy efficiency of the coding system. Moreover, McGrath is directed to controlling the temperature of a cooling fluid used for coding purposes, which serves to substantially increase the number of components necessary as well as increasing the cost of the system. Other systems known in the art have similar shortcomings.
Accordingly, there exists a need for a cooling system that does not require the use of expensive or energy-inefficient components while still achieving sufficient cooling capability.
This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention.
The cooling system may include a control unit that includes a thermostat, a sensor and a controller. The control unit may receive a set point temperature from the thermostat as set by a user. The control unit may also receive an air chamber temperature from the sensor. When the sensor detects the air chamber temperature is higher than the set point temperature, the controller may signal the well pump to initiate delivery of water from a cool water source through the piping subsystem to an air conditioning apparatus, defined as a liquid-to-air heat exchanger. Air chamber fluid, in this case air, may be moved along the liquid-to-air heat exchanger to transfer heat from the air chamber to the cool water, which has now been warmed by the liquid-to-air heat exchanger. In some embodiments, the air chamber air may be moved by a fan. As a result, the air chamber temperature may lower. Simultaneously, the water temperature rises becoming warmed water. In some embodiments, the warmed water may be piped through a solar heating system to transfer additional heat to the warmed water and creating heated water. At this point, the heated water may be piped to a distribution module that is structured for heated water distribution.
In some embodiments, the distribution module may be a warm water tank and in other embodiments the distribution module may be a hot water heater or hot water heater tank. Structuring the distribution module as a traditional hot water heater or hot water heater tank may reduce electricity consumption since the water being piped into the tank is already warmed or heated. However, in this embodiment, the hot water heater or hot water heater tank may include a distribution control unit with a distribution controller, a distribution thermostat, and a distribution sensor whereby the distribution controller signals the well pump to initiate the delivery of water from a cool water source when the distribution sensor detects water within the hot water heater falls below a set point temperature. In any embodiment, the distribution module may retain a portion of the warmed and/or heated water for later use. However, in some embodiments the distribution module may not retain any water.
The distribution module may be structured to distribute warmed and heated water to a location different than the original cool water source. In some embodiments, this may be external to the structure containing the cooling system via external componentry. In other embodiments, this may be internal to the structure containing the cooling system via internal componentry. Yet other embodiments may have the warmed and/or heated water distributable both inside and outside of the containing structure with both external componentry and internal componentry stemming from the distribution module.
The cooling system may utilize the control unit and controller to initiate and cease the flow of water from the cool water source to the distribution module. For example, this may occur when the air chamber reaches a temperature equal to the set point temperature. However, some embodiments may have the cooling system continuously running through the plumbing subsystem and expelled through the external componentry without the use of a control unit. Likewise, certain embodiments may not use the distribution control unit to control the flow of cool water through the plumbing subsystem.
The cooling system may include the liquid-to-air heat exchanger located within one level of a structure or building and the plumbing subsystem may be structured to route warmed water from the liquid-to-air heat exchanger through another level of the structure or building before moving the warmed water to the distribution module located on the original level. In other embodiments, the cool air system may include the distribution module located on a level different from the original level. Yet other embodiments may include a plurality of distribution modules located on a plurality of levels.

The first air flow blocking member 330 may be positioned so as to generally prevent the backflow of air through the air intake grille 210 into the air chamber 122. More specifically, the first air flow blocking member may be positioned so as to generally circumscribe the fan 312, preventing air from flowing around the fan 312 when the fan 312 is operating. By preventing such a backflow, all air that is moved by the fan 312 must exit the air conditioning assembly 124 through the air output section 212.
In some embodiments, the air conditioning apparatus 124 may further comprise a second air flow blocking member 340. The second air flow blocking member 340 may be positioned so as to facilitate the flow of air that has flowed across the heat exchanger 302 to exit the air conditioning apparatus 124 through the air output section 212. More specifically, the second air flow blocking member 340 may prevent air that has flowed across the heat exchanged 302 and exchanged thermal energy therewith from flowing down into the redirection chamber 350. This may reduce the turbulence of the flow of air through the air conditioning apparatus 124.

Additionally, the housing 214 may be formed of light gauge steel. However, such a material is exemplary only, and the housing 214 may be formed of any material which is suitable for carrying the various components of the air conditioning apparatus 124. Furthermore, the housing 214 may be configured so as to be positioned within the air chamber 122 at a desired location. For example, the housing 214 may be configured so as to be attachable to a wall, ceiling, or any other structure associated with the air chamber 122.

Furthermore, the control circuit may determine if the set point temperature is less than the second temperature. If the set point temperature is not less than the second temperature, then the method may terminate at Block 899. If, however, the set point temperature is less than the second temperature, the method may continue at Block 816 where a first volume of water may be delivered to a heat exchanger. The first volume of water may be drawn from a cool water source and may have a first temperature. Moreover, the water may be delivered using an inlet piping component as described hereinabove. Additionally, at Block 816, the first volume of water may be passed through an inlet orifice of the heat exchanger and along an interior surface of a tube thereof.
At Block 818, a first volume of air may be moved from an air chamber along the heat exchanger. The air may be moved by a fan, as described hereinabove, which may be controlled by the control circuit. Moreover, the air may be moved across a heat sink of the heat exchanger, increasing the thermal transmission rate thereof.
At Block 820, heat may be transferred from the first volume of air to the first volume of water through the heat exchanger. Such a transfer of heat may alter the first volume of air to exhibit a first-cycle conditioned temperature that is less than the second temperature. Moreover, the first volume of water may be altered to exhibit a first-cycle altered temperature that is greater than the first temperature and approximately equals the first-cycle conditioned temperature. In some embodiments, the first-cycle altered temperature may be less than the first-cycle conditioned temperature.
At Block 822, the first volume of air, which now has a first-cycle conditioned temperature, may be moved to the air chamber. Such movement may be accomplished by operation of the fan. More specifically, such movement may be accomplished by the fan establishing a flow of air that results in the displacement of the first volume of air away from the heat exchanger and through an air output section. The method may then end at Block 899.

At Block 914, the set point temperature may be compared to the second temperature. The comparison may be performed by a control circuit as described hereinabove. Furthermore, the control circuit may determine if the set point temperature is less than the second temperature. If the set point temperature is not less than the second temperature, then the method may terminate at Block 999. If, however, the set point temperature is less than the second temperature, the method may continue at Block 916 where a solenoid valve of the inlet piping component is opened so as to allow fluid to flow past. Opening the valve may enable Block 918, where a first volume of water may be delivered to a heat exchanger. The first volume of water may be drawn from a cool water source and may have a first temperature. Moreover, the water may be delivered using an inlet piping component as described hereinabove. Additionally, at Block 816, the first volume of water may be passed through an inlet orifice of the heat exchanger and along an interior surface of a tube thereof.
In some embodiments, the first volume of water may be prevented from being delivered by using a shutoff valve to prevent water from flowing through the solenoid valve. Accordingly, the shut off valve may be operated to selectively stop the first volume of water from passing to the solenoid valve.
At Block 920 a first volume of air may be moved from an air chamber along the heat exchanger. The air may be moved by operating a fan, as described hereinabove, which may be controlled by the control circuit. Moreover, the air may be moved across a heat sink of the heat exchanger, increasing the thermal transmission rate thereof.
At Block 922, heat may be transferred from the first volume of air to the first volume of water through the heat exchanger. Such a transfer of heat may alter the first volume of air to exhibit a first-cycle conditioned temperature that is less than the second temperature. Moreover, the first volume of water may be altered to exhibit a first-cycle altered temperature that is greater than the first temperature and approximately equals the first-cycle conditioned temperature. In some embodiments, the first cycle altered temperature may be less than the first-cycle conditioned temperature.
At Block 924, the first volume of air, which now has a first-cycle conditioned temperature, may be moved to the air chamber. Such movement may be accomplished by operation of the fan. More specifically, such movement may be accomplished by the fan establishing a flow of air that results in the displacement of the first volume of air away from the heat exchanger and through an air output section.
At Block 926, a third temperature of air contained within an air chamber may be measured. The measurement of the third temperature may be contemporaneous with the movement of the first volume of air into the air chamber, or at a period shortly thereafter. At Block 928, the set point temperature may be compared to the third temperature. The comparison may be performed by a control circuit as described hereinabove. Furthermore, the control circuit may determine if the set point temperature is less than the third temperature. If the set point temperature is not less than the third temperature, then the method may continue at Block 930 where the control circuit may close the solenoid valve and stop the operation of the fan. The solenoid valve may be closed responsive to a signal from the control circuit, and the operation of the fan may be stopped responsive to a signal received from the control circuit. The method may then end at Block 999.
If, however, the set point temperature is less than the second temperature, the method may continue at Block 932 where the first volume of water may be passed out of the heat exchanger and discharged. More specifically, the first volume of water may be passed along an interior surface of a tube of the heat exchanger and through an outlet orifice. Furthermore, the first volume of water may be discharged using an outlet piping component in fluidic communication with the outlet orifice.
The method may continue at Block 934 where a second volume of water may be delivered from the cool water source to the heat exchanger using the inlet piping component and passing the second volume of water through the inlet orifice and along the interior surface of the tube of the heat exchanger. At Block 936, a second volume of air may be moved from the air chamber along the heat exchanger using the fan. More specifically, the second volume of air may be moved across the heat sink of the heat exchanger.
At Block 938, heat may be transferred from the second volume of air to the second volume of water through the heat exchanger. Such a transfer of heat may alter the second volume of air to exhibit a second-cycle conditioned temperature that is less than the third temperature. Moreover, the second volume of water may be altered to exhibit a second-cycle altered temperature that is greater than the first temperature and approximately equals the second-cycle conditioned temperature. In some embodiments, the second-cycle altered temperature may be less than the second-cycle conditioned temperature
At Block 940, the second volume of air, which now has a second-cycle conditioned temperature, may be moved to the air chamber. Such movement may be accomplished by operation of the fan. More specifically, such movement may be accomplished by the fan establishing a flow of air that results in the displacement of the first volume of air away from the heat exchanger and through an air output section. Additionally, at Block 942, second volume of water may be passed out of the heat exchanger and discharged through the outlet orifice and using an outlet piping component in fluidic communication with the outlet orifice as described hereinabove. The method may then end at Block 999.
In some embodiments, the distribution module 944 may be a warm water tank 644 and in other embodiments the distribution module 944 may be a hot water heater or hot water heater tank. Structuring the distribution module 944 as a traditional hot water heater or hot water heater tank may reduce electricity consumption since the water being piped into the tank is already warmed or heated. However, in this embodiment, the hot water heater or hot water heater tank may include a distribution control unit 904 with a distribution controller 911, a distribution thermostat 906, and a distribution sensor 905 whereby the distribution controller 911 signals the well pump 175 to initiate the delivery of water from a cool water source 114 when the distribution sensor 905 detects water within the hot water heater falls below a set point temperature. In any embodiment, the distribution module 944 may retain a portion of the warmed and/or heated water for later use. However, in some embodiments the distribution module 944 may not retain any water.
The distribution module 944 may be structured to distribute warmed and heated water to a location different than the original cool water source 114. In some embodiments, this may be external to the structure containing the cooling system 1000 via external componentry 908. In other embodiments, this may be internal to the structure containing the cooling system 1000 via internal componentry 907. Yet other embodiments may have the warmed and/or heated water distributable both inside and outside of the containing structure with both external componentry 908 and internal componentry 907 stemming from the distribution module 944.
The cooling system 1000 may utilize the control unit 901 and controller 910 to initiate and cease the flow of water from the cool water source 114 to the distribution module 944. For example, this may occur when the air chamber 122 reaches a temperature equal to the set point temperature. However, some embodiments may have the cooling system 1000 continuously running through the plumbing subsystem 150 and expelled through the external componentry 908 without the use of a control unit 904. Likewise, certain embodiments may not use the distribution control unit 904 to control the flow of cool water 114 through the plumbing subsystem 150.
The cooling system 1000 may include the liquid-to-air heat exchanger 124 located within one level of a structure or building and the plumbing subsystem may be structured to route warmed water from the liquid-to-air heat exchanger 124 through another level of the structure or building before moving the warmed water to the distribution module 944 located on the original level. In other embodiments, the cool air system 100 may include the distribution module 944 located on a level different from the original level. Yet other embodiments may include a plurality of distribution modules 944 located on a plurality of levels.
