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.

[ Now that the invention has been described, what is claimed is:] [3.] A combination subcool and precool heat exchanger system that utilizes stored condensate water from an air conditioner or heat pump and any needed make-up water that is first pumped across a first heat exchanger while the cold, dry building exhaust air is also passed over said first heat exchanger for first evaporatively subcooling the liquid refrigerant that has passed through the condenser of said air conditioner or heat pump and then the air exhausting from the first heat exchanger subsequently passed through a second water wetted heat exchanger (a precooler) for subsequently precooling the hot gas discharge refrigerant from a compressor before said refrigerant passes into the condenser of said air conditioner or heat pump, comprising in combination:a) the first heat exchanger, a subcooler connected in fluid communication with the output of the condenser, enabling the refrigerant to flow through said subcooler after first flowing through the condenser;b) the second heat exchanger, a precooler connected in fluid communication with the output of a compressor, enabling the hot gas refrigerant to flow through said precooler before passing into the condenser;c) a reservoir system the subcooler and precooler sits in that receives the condensate and make-up water supplies;d) said subcooler and precooler connected in fluid communication with the output of a pump that pumps the stored condensate and make-up water through a control system that enables the correct amount of condensate and makeup water to flow across and wet the surfaces of said subcooler and said precooler for evaporative cooling thereof;e) said subcooler further connected in fluid communication with cold, dry building exhaust air that subsequently cools by evaporation the water flowing over the subcooler which in turn cools the liquid refrigerant flowing through the subcooler; andf) said precooler connected in fluid communication with the airflow output of the subcooler of the previously used building exhaust air, said previously used building exhaust air passing through said condensate and make-up water supply wetted precooler heat exchanger, where said exhaust air cools by evaporation the water flowing over the precooler which in turn precools the hot gas refrigerant flowing through the precooler; andg) means for said condensate and make-up water to overflow to discharge, whereby said subcool and precool system utilizes said evaporative cooling for providing maximum available subcooling to the liquid refrigerant and maximum available precooling to the hot gas discharge refrigerant of said air conditioner or heat pump.
