Abstract: A system for providing liquid refrigerant subcooling by means of evaporative cooling utilizing the condensate water of said air conditioner, refrigeration/heat pump system and/or other water supply to wet the surface of the subcool heat exchanger and pass the dry exhaust air across the wetted surface of the subcool heat exchanger. A system for providing hot gas discharge refrigerant precooling into the primary condenser of an air conditioner, refrigeration or heat pump system by evaporative cooling utilizing the condensate water of said system and/or other water supply to wet the surface of the precool heat exchanger and then passing the cold, dry exhaust air across the wetted surface of the precool heat exchanger. A combination subcooler/precooler system where the cold dry building exhaust air is used to evaporatively subcool the liquid refrigerant in the water wetted (or dry) subcooler and then used to conductively cool the hot gas refrigerant.

Abstract: A hot water heater with a built in refrigerant heat recovery system is provided. A thermosyphon and Coriolis force powered refrigeration heat recovery unit is integrated into the tank of a conventional gas or electric hot water heater. The heat recovery unit is placed beneath the outer skin of the hot water heater to decrease the number of exterior connections and increase the ease of installation. The use of the Coriolis effect increases the flow rate and thus the efficiency of the heat transfer system.

Abstract: An evaporator system comprised of two individual refrigerant circuits, integrated in such a way that if one circuit is not in operation, no portion of the airflow through the evaporator fails to come into contact with the refrigerant in the active circuit. This eliminates the possibility of so-called bypass air (air passing through inactive region of evaporator). An extreme example of bypass air is illustrated in the use of a split face evaporator where on half of the evaporator is active and the other half is inactive. The purpose of such an integrated dual circuit evaporator being to improve part load performance of a refrigerating or air conditioning system when one circuit of the system is inactive.

Abstract: A multiple hermetic compressor assembly comprising a first compressor and an adjacent, second compressor interconnected by a hot gas pressure discharge manifold, a suction gas pressure equalization manifold, a suction manifold and an oil equalization manifold, the manifolds including a plurality of the turns extending at right angles that minimizes vibrational-associated manifold stress failures by providing for adequate vibrational absorption in the manifolds and reduces hot gas discharge interference between the compressors.

Abstract: A system for providing liquid refrigerant subcooling. Subcooling heat exchange is accomplished by directing and controlling the flow of said harvest and/or melt water through a refrigerant to fluid heat exchanger, or by a passive heat sink method whereby the liquid refrigerant subcooler sits in a non-pumped open reservoir that overflows at each harvest cycle. A system for providing hot gas discharge refrigerant precooling. Precooling heat exchange is accomplished by directing and controlling the flow of said harvest and/or melt water through a refrigerant to fluid heat exchanger, or by a passive heat sink method whereby the hot gas discharge refrigerant precooler sits in a non-pumped open reservoir that overflows at each harvest cycle. A system that combines the first two systems described above for providing both the benefits of subcooling and precooling with the same harvest and/or melt water supply being used twice.

Abstract: A system for providing liquid refrigerant subcooling, by means of evaporative cooling utilizing the condensate water of said air conditioner, refrigeration/heat pump system and/or some other water supply to wet the surface of the subcool heat exchanger and pass the dry exhaust air across the wetted surface of the subcool heat exchanger. A system for providing hot gas discharge refrigerant precooling into the primary condenser of an air conditioner, refrigation or heat pump system by evaporative cooling utilizing the condensate water of said system and/or other water supply to wet the surface of the precool heat exchanger and then passing the cold, dry exhaust air across the wetted surface of the precool heat exchanger. A combination subcooler/precooler system where the cold dry building exhaust air is used to evaporatively subcool the liquid refrigerant in the water wetted (or dry) subcooler and then used to conductively cool the hot gas refrigerant.

Abstract: A solar-based power generating system including an electrical alternator or generator for generating electrical power in which the alternator or generator is driven by a refrigerant circulating through a closed-loop heat transfer system including an evaporator exposed to solar energy and a condenser disposed within a large heat sink such as a body of water.
