Abstract: An apparatus comprises a subcooler, such as a vented tube/plate or tube on tube heat exchanger, and a pre-cooler and/or post-heater, which may be a vented tube/plate or tube on tube heat exchanger. The subcooler and pre-cooler and/or post-heater are connected in fluid communication with each other (in series) and with a refrigerant output and input of a condenser. For example, the refrigerant output goes into the subcooler, and the refrigerant input comes out of the precooler and/or post-heater. A working fluid (e.g. coolant), such as water or glycol or other working fluid, is forced, such as by pumping, first through the subcooler and then through the precooler and/or post-heater. Flow rate of the working fluid through the apparatus may be regulated such that the refrigerant is first subcooled to an incoming fluid's temperature and then to pre-cool the refrigerant to approximately its saturated-vapor state, when the system is operating to provide a refrigeration effect.

Said system having an optimized heat exchanger tube-on tube spirally wound, with wind direction to take advantage of the Coriolus force effect, for optimized refrigerant and other fluid turbulence and therefore optimized heat transfer, and optimum location of said heat exchanger and sizes of connecting tubes to minimize refrigerant friction related pressure loss, and to optimize heat transfer, refrigerant flow and thermosyphonic second fluid flow through said heat exchanger.

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 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 low pressure suction side refrigerant to liquid refrigerant heat exchanger, located in the refrigeration circuit in such a way that the sensor (and external equalizer tube, if applicable) is located downstream of the low pressure refrigerant outlet of the heat exchanger, provides for effectively eliminating both the superheat and flash gas loss regions of the evaporator which in turn increases the mass flow through the evaporator and increases the refrigerating capacity of the evaporator at very little increase in compressor power thereby providing for increased system efficiency for refrigerating or cooling purposes. On the heating side, heat rejection capacity of a heat pump is increased even more dramatically because of the heat reclaim of the flash gas loss heat, which provides for even greater efficiency increases for heating applications.
