ABSTRACT:
First, a system for providing liquid refrigerant subcooling, subsequent to that subcooling accomplished by the primary condenser of an air conditioner or heat pump, by means of evaporative cooling utilizing the condensate water of said air conditioner or heat pump system and/or some other water supply to wet the surface of the subcool heat exchanger and then passing the cold, dry building exhaust air required for good indoor air quality across the wetted surface of the subcool heat exchanger. Said exhaust air could be used after first undergoing a sensible heat exchange with the incoming make up air. Said subcooling providing for an increased refrigeration capacity, and efficiency of the system.
Secondly, a system for providing hot gas discharge refrigerant precooling before said hot gas passes into the primary condenser of an air conditioner or heat pump, by means of evaporative cooling utilizing the condensate water of said air conditioner or heat pump system and/or some other water supply to wet the surface of the precool heat exchanger and then passing the cold, dry building exhaust air required for good indoor air quality across the wetted surface of the precool heat exchanger. Said precooler providing lower power consumption of the compressor, lower head pressure, increased mass flow of the refrigerant and improved efficiency of the primary condenser of the air conditioning or heat pump system.
Said exhaust air could be used after first undergoing a sensible heat exchange with the incoming make up air on either the subcooler or precooler.
Finally, a combination subcooler and precooler system where the cold dry exhaust air is first used to evaporatively subcool the liquid refrigerant in the water wetted subcooler and then subsequently used to conductively cool the hot gas refrigerant passing through a dry surface precooler or alternately used to evaporatively cool the wetted surface of the precooler thereby evaporatively precooling the hot gas refrigerant passing through the precooler.
