DETAILED DESCRIPTION

(6) While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

(7) The present invention provides a novel and efficient air conditioning system operably configured to provide heating and cooling to a building without the need to circulate long lines of pressurized, which is prone to leaking, throughout the building, as is required in currently-available air conditioning systems. Instead, embodiments of the invention provide a closed-loop air-to-water system that climatizes, stores, and circulates fluid, such as water or other types of liquid refrigerant, between storage tanks and an air handler located within a building. Subsequently, air within the building is climatized in the air handler by removing thermal energy with the climatized water. The cold climatized air is then distributed throughout the building. As used herein, climatized means cooled to a temperature that is below an ambient temperature, or heated to a temperature that is above an ambient temperature. For example, if the ambient temperature of water in the closed-loop air-to-water system is 75, and the water is cooled to a temperature of 55, the 55 water may be referred to as climatized water. Similarly, if the ambient temperature of water in the closed-loop air-to-water system is 60, and the water is heated to a temperature of 70, the 70 water may be referred to as climatized water. The same principles and definitions apply to climatized air, meaning air that has been cooled or heated to a temperature that is different from that of the ambient temperature, such that the climatized air may be distributed to a building to either heat or cool the building.

(8) Referring now to FIG. 1, one embodiment of the present invention is shown in a perspective view. FIG. 1 shows several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a closed-loop air-to-water system 100, as shown in FIG. 1, includes a condenser assembly 102, a water climatization assembly 103, and an air handler assembly 106 within a building 116. FIG. 1 provides dashed lines generally indicating where each of the three assemblies could be thought to be separated from the other. The lines are imaginary and for reference only. In practice, because the three assemblies are connected and interoperate, some components, such as lines and pumps, among others, are shared between and could be considered to be a part of more than one of the three main assemblies shown and described herein.

(9) Referring still to FIG. 1, in one embodiment, the closed-loop air-to-water system 100 includes a condenser assembly 102 located outside or at least able to exhaust air outside of a building. As used herein, building means a stationary structure, such as a home, office, school, cabin, or other structure that provides an interior shelter from an exterior environment. FIG. 1 shows one such building, labeled as 116. The condenser assembly 102 may include a compressor 104 (the details of which are known in the art and not shown here in detail), which may be located within a condenser fan tower 126, or which may form a separate structure from the condenser fan tower 126. Similar to prior-art air conditioning systems, the compressor 104 may be operably configured to compress or pressurize fluid, such as refrigerant, thereby creating a high-pressure and high-temperature refrigerant (e.g. pressurized refrigerant) within a refrigerant line 105.

(10) Referring now to FIG. 2, the pressurized refrigerant may then be transferred from the compressor 104 to at least one condenser coil, which may be located within the condenser fan tower 126, or which may be separate from the condenser fan tower 126. When the pressurized refrigerant passes through the at least one condenser coil, ambient air 208 may simultaneously enter the condenser fan tower 126 and absorb heat from the pressurized refrigerant by passing over the at least one condenser coil, thereby removing heat from the pressurized refrigerant and producing cooled pressurized refrigerant. The condenser fan tower 126 may then exhaust the warmer air 210 into the ambient environment surrounding the condenser fan tower 126, similar to traditional land-based air conditioning systems, but different from traditional marine-based air conditioning systems, which require water to absorb the heat generated by pressurizing refrigerant. In the process, the refrigerant within the at least one condenser coil may then be compressed, turned into a liquid, and then cooled. In accordance with the invention, this cooled pressurized refrigerant is pumped through condenser refrigerant line 105 to a thermal mixing block 202, where it is utilized to cool a cooling medium, as will be explained below, but generally the pressurized refrigerant is depressurized with a thermal expansion valve 201, thereby lower its temperature significantly. Once the depressurized refrigerant leaves the thermal mixing block 202, it returns to the condenser fan tower 126 to start the compressing/cooling process over again.

(11) Referring again to FIG. 1, the water climatization assembly 103 includes at least one thermally insulated climatized-fluid storage tank 110 coupled to a fluid pipe 107 that runs next to and is thermally coupled to the thermal mixing block 202. In one embodiment, water within the water climatization assembly 103 circulates in physical/thermal contact with the refrigerant within the condenser refrigerant line 105 within the thermal mixing block 202, thereby acclimatizing the water. That is, the water going to the thermal mixing block can be considered to be non-climatized water or fluid. For example, the water of the water climatization assembly 103 may become cooler as it transfers heat to the cooled depressurized refrigerant within the condenser refrigerant line 105 in thermal mixing block 202. In one embodiment, the thermal mixing block 202 may be a structure that includes an expansion valve to allow the pressurized refrigerant to depressurize, providing chilled depressurized refrigerant in thermal mixing block 202. The thermal mixing block 202 places the condenser refrigerant line 105, with the depressurized chilled refrigerant, and the fluid pipe 107 in a coaxial arrangement so that the fluid within the fluid pipe 107 passes or flows around all sides of the condenser refrigerant line 105 for a distance, thereby maximizing the exterior surface area of the condenser refrigerant line 105 for thermal contact with the fluid within the fluid pipe 107. In another embodiment, chilled refrigerant within condenser refrigerant line 105 passes or flows around all sides of the fluid pipe 107 for a distance, thereby maximizing the exterior surface area of the fluid pipe for thermal contact with the refrigerant within the condenser refrigerant line 105. Thus chilled depressurized refrigerant becomes heated depressurized refrigerant upon heat transferring from the water line 107 to the refrigerant line 105, The heated depressurized refrigerant is returned to the compressor 104 in the condenser fan tower 126 in an ongoing process, as needed. Generally, in summary, the condenser coil, having received the pressurized refrigerant from the compressor 104, may transfer thermal energy (i.e. heat) with water (or other fluid) within the fluid pipe 107 to create climatized water for distribution through the air handler assembly 106.

(12) The cold or chilled water exits the thermal block 202 and travels through fluid pipe 107 to a pump 120. The pump 120 pushes the cold water onwards through the fluid pipe 107 and into a climatized-fluid storage tank 110. Ideally, the climatized-fluid storage tank 110 is thermally insulated and will maintain the cold temperature of the water for a long amount of time, preferably hours, if not days. Therefore, chilled water can remain at its chilled temperature within the climatized-fluid storage tank 110 when the system is not in use. The climatized-fluid storage tank 110 may be disposed beneath a ground surface 122, as shown in FIG. 1, which may provide insulation for the climatized-fluid tank 110. Of course, the climatized-fluid storage tank 110 may also be disposed above the ground surface 122. In some embodiments climatized-fluid storage tank 110 may be constructed like a DEWAR tank, with inner and outer walls and a vacuum separation between the walls, where the inner wall forms a tank in which the chilled water is stored.

(13) The climatized-fluid storage tank 110 has two exit portsa water pipe 111 and crossover tube 119. Under ideal operation, the cold water inside of the climatized-fluid storage tank 110 is removed from the climatized-fluid storage tank 110 by a water pump 112 disposed downstream from the climatized-fluid storage tank 110 that places a vacuum on the water pipe 111. Water pump 112, when operating, pulls water from the climatized-fluid storage tank 110 and sends the cold water downstream through pipe 111 and into the air handler assembly 106. In one embodiment, the air handler assembly 106 is within the building 116.

(14) Referring now to FIG. 3, an interior portion of the air handler assembly 106 is shown in detail. In one embodiment, the air handler 114 may include a climatized fluid coil 302. In one embodiment, the climatized fluid coil 302 is formed in a serpentine pattern that allows air to pass through said coil. Serpentine coils are known in the art and not shown here in detail. The climatized fluid coil 302 is be fluidly coupled to the climatized-fluid storage tank 110 through the pipe 111. In one embodiment, the climatized fluid coil 302 may be operably configured to receive climatized water stored within the climatized-fluid storage tank 110 and pumped by the pump 112, and may be operably configured to circulate the climatized water throughout the air handler assembly 106.

(15) Still referring to FIG. 3, in one embodiment, the air handler 114 may be disposed to receive ambient air 308 from inside of the building 116. The ambient air 308 may have a temperature which may be referred to as room temperature. As used herein, room temperature means the ambient temperature of at least a portion of the building 116. In one embodiment, when the air handler 114 receives ambient air 308 from inside of the building 116, the ambient air 308 may pass over the climatized fluid coil 302. As such, the climatized fluid coil 302 may be operably configured to transform the ambient air 308 to climatized air 310 by transferring thermal energy from the climatized water flowing through the climatized fluid coil 302 to the ambient air 308. In one embodiment, the climatized air 310 may then be distributed to at least a portion of the building 116 through at least one air duct 124, thereby either cooling or heating the at least a portion of the building 116, depending on the goal of the closed-loop air-to-water system 100. In one embodiment, the programming of the closed-loop air-to-water system 100 may be accomplished through a thermostat 118, which may control the desired temperature of the climatized air 310.

(16) Referring again to FIG. 1, the air handler 114 may be fluidly coupled to a to-be-recycled-climatized-fluid storage tank 108 through return water line 113. In one embodiment, the to-be-recycled-climatized-fluid storage tank 108 may be disposed beneath the ground surface 122, as shown in FIG. 1, which may provide insulation for the recycled-climatized-fluid storage tank 108. In another embodiment, the recycled-climatized-fluid storage tank 108 may be disposed above the ground surface 122. In one embodiment, the recycled-climatized-fluid storage tank 108 may be disposed to receive climatized water from the climatized fluid coil 302 disposed within the air handler 114. Depending on the temperature of the climatized water that is received by the to-be-recycled-climatized-fluid storage tank 108, the to-be-recycled-climatized-fluid storage tank 108 may redistribute the water back into the air handler assembly 106, thereby continuing to climatize the building 116. For example, if the closed-loop air-to-water system 100 is set to cool, and the climatized water output by the air handler 114 via pipe 113 received by the to-be-recycled-climatized-fluid storage tank 108 is sufficiently cool to effectively cool at least a portion of the building 116, the to-be-recycled-climatized-fluid storage tank 108 may redistribute the climatized water back to the climatized-fluid storage tank 110 through the crossover tube 119, which may flow in either direction between the two tanks 108, 110, depending on the conditions therein. The climatized-fluid storage tank 110 and the to-be-recycled-climatized-fluid storage tank 108 do not necessarily have to be separate structures as shown in FIGS. 1 & 2. In an embodiment of the present invention, the climatized-fluid storage tank 110 and the to-be-recycled-climatized-fluid storage tank 108 can be a single structure with multiple chambers within. Preferably, the chambers would be thermally separated from each other.

(17) Alternatively, if the climatized water received by the to-be-recycled-climatized-fluid storage tank 108 is not sufficiently cool to effectively cool at least a portion of the building 116, the to-be-recycled-climatized-fluid storage tank 108 may distribute that water to the block 202 to become re-climatized, i.e., cooled again. Since the climatized water continues to flow throughout the closed-loop air-to-water system 100, the water portion of the closed-loop air-to-water system 100 may be referred to as a closed-loop system, with minimal water loss throughout the closed-loop air-to-water system 100.

(18) In one embodiment, the to-be-recycled-climatized-fluid storage tank 108 may be in direct fluid communication with the climatized-fluid storage tank 110 at crossover tube 119. In one embodiment, climatized water may flow from the to-be-recycled-climatized-fluid storage tank 108 to the climatized-fluid storage tank 110 through crossover tube 119, in order to redistribute climatized water through the air handler assembly 106 to the air handler 114. In one embodiment, climatized water may flow from the climatized-fluid storage tank 110 to the to-be-recycled-climatized-fluid storage tank 108 through crossover tube 119, in order to store climatized water in the to-be-recycled-climatized-fluid storage tank 108. In some embodiments the crossover tube 119 can be connected to the climatized-fluid storage tank 110 at an upper portion (i.e. above halfway), or at a top, of the climatized-fluid storage tank 110, and can likewise connect to a top portion or top of the to-be-recycled-climatized-fluid storage tank 108.

(19) Pump 112 is coupled to the air handler assembly 106 and may be temperature controlled. In one embodiment, the temperature controlled pump 112 is disposed downstream from the climatized-fluid storage tank 110 and upstream from the air handler 114. When thermostat 118 detects the need to heat or cool the building 116, the pump 112 is engaged, which then pulls climatized water from the climatized-fluid storage tank 110 to the air handler 114. Advantageously, this process can take place without running any component of the condenser assembly 102, thereby saving a great deal of energy in comparison to prior-art cooling systems.

(20) The water inside the climatized-fluid storage tank 110 needs to be at the proper temperature when the temperature controlled pump 112 moves it to the air handler 114. Therefore, the storage tanks 108, 110 may be coupled to a temperature detector 121 that detects the temperature of the climatized water housed within the climatized-fluid storage tank 110. The temperature detector 121 controls the pump 120. In one embodiment, upon reaching a threshold temperature (i.e., above 70 for a cooling system, or below 60 for a warming system), the temperature controlled pump 120 may remove the climatized water from the recycled-climatized-fluid storage tank 108 to be circulated to the thermal block 202 in order to re-climatize the water, and subsequently be re-distributed to the climatized-fluid storage tank 110. In one embodiment, the air handler 114 may include a temperature controlled pump that is operably configured to pump climatized water to the to-be-recycled-climatized-fluid storage tank 108 to be distributed to the thermal block 202 to be re-climatized.

(21) FIGS. 1-3 will be described in conjunction with the process flow chart diagrams of FIGS. 4-5. Although FIGS. 4-5 show a specific order of executing the process steps, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more blocks shown in succession may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted in FIGS. 4-5 for the sake of brevity. In some embodiments, some or all of the process steps included in FIGS. 4-5 can be combined into a single process.

(22) Referring now to FIG. 4 in particular, with reference to FIGS. 1-3, a method of providing heating or cooling to a building 116 is described in greater detail. The method may begin at step 400 and proceed directly to step 402, in which the closed-loop air-to-water system 100 is provided with the features and configurations described herein above. The method may then proceed to step 404, which includes pumping refrigerant through the condenser coil 104 and thermal block 202 to climatize the non-climatized water by either cooling the water to a temperature that is below an ambient temperature, or heating the water to a temperature that is above an ambient temperature, depending on the goal of the closed-loop air-to-water system 100. For example, if the closed-loop air-to-water system 100 is programmed to provide cooling to the building 116, the water will be climatized (climatized water/fluid) by the thermal block 202 to a temperature that is below an ambient temperature. Alternatively, if the closed-loop air-to-water system 100 is programmed to provide heating to the building 116, the water will be climatized by the thermal block 202 to a temperature that is above an ambient temperature. The method may then proceed to step 406, in which the climatized water is pumped from the at least one thermal mixing block 202 to the climatized-fluid storage tank 110, where the climatized water may be stored before being distributed through the remainder of the air handler assembly 106.

(23) The method of providing heating or cooling to the building 116 may proceed to step 408, in which the climatized water is pumped from the climatized-fluid storage tank 110 to the air handler 114 disposed in an interior portion of the building 116. During step 408, the climatized water may flow through the climatized fluid coil 302, thereby making the climatized fluid coil 302 either cool in order to cool at least a portion of the building 116, or warm in order to warm at least a portion of the building 116.

(24) The method of providing heating or cooling to the building 116 may then proceed to step 410, in which the air handler 114 may draw ambient air 308 into the air handler 114, passing the ambient air 308 over the climatized fluid coil 302. As such, the ambient air 308 may receive thermal energy from the climatized water flowing through the climatized fluid coil 302 to either cool or heat at least a portion of the building 116. For example, if the closed-loop air-to-water system 100 is programmed to provide cooling to at least a portion of the building 116, the ambient air 308 will become cooler by passing over the cool climatized fluid coil 302. Similarly, if the closed-loop air-to-water system 100 is programmed to provide heating to at least a portion of the building 116, the ambient air 308 will become warmer by passing over the warm climatized fluid coil 302. The climatized air 310 created by passing ambient air 308 over the climatized fluid coil 302 may then be distributed to at least a portion of the building 116 through the at least one air duct 124.

(25) Referring now to FIG. 5, after the climatized water within the climatized fluid coil 302 transfers thermal energy to the ambient air 308 drawn into the air handler 114, the climatized water may no longer be of an optimal temperature to provide at least one of heating and cooling to the building 116. As such, in step 500, the climatized water is pumped from the climatized fluid coil 302 to the to-be-recycled-climatized-fluid storage tank 108, which may be disposed exterior to the building 116. The climatized water may be stored within the recycled-climatized-fluid storage tank 108 for redistribution within the closed-loop air-to-water system 100.

(26) During step 502, a decision is made regarding the use of the climatized water within the recycled-climatized-fluid storage tank 108. In one embodiment, a temperature detector 121 coupled to the recycled-climatized-fluid storage tank 108 may measure the temperature of the climatized water stored within the recycled-climatized-fluid storage tank 108 to determine whether the climatized water may be reused within the closed-loop air-to-water system 100. For example, if the climatized water held within the recycled-climatized-fluid storage tank 108 is sufficiently cool to effectively cool at least a portion of the building 116, the recycled-climatized-fluid storage tank 108 may redistribute the climatized water through the crossover tube 119. Such distribution to the climatized-fluid storage tank 110 occurs during step 504. Upon being received by the climatized-fluid storage tank 110, the climatized water may be redistributed through the closed-loop air-to-water system by repeating steps 408-412 and 500-502.

(27) Alternatively, if the climatized water received by the recycled-climatized-fluid storage tank 110 is not sufficiently cool (or hot, depending on the desired settings) to effectively cool at least a portion of the building 116, the recycled-climatized-fluid storage tank 108 may distribute the climatized water to the thermal block 202 disposed within the condenser assembly 102. Such distribution to the thermal block 202 occurs during step 404 and the re-climatized water may be distributed throughout the air handler assembly 106 by repeating steps 406-412 and 500-502.

(28) An air conditioning system for providing heating and cooling to a building has been disclosed that includes a condenser system which utilizes air to remove heat from pressurized refrigerant, and a closed-loop air-to-water system which stores and circulates climatized water to a building, thereby allowing for the selective heating and/or cooling of the building by transferring thermal energy from the climatized water to ambient air within the building.
