ABSTRACT:
For use with a refrigeration system to increase cooling efficiency, between an outdoor condenser and an indoor evaporator, a refrigerant receiver-sub-cooler is provided including, immediately before the receiver-sub-cooler, but still within the high pressure liquid refrigerant portion of the system, a high flow, low pressure release check valve, having a generally flat backside refrigerant flow control element, that serves as an incremental expansion device to cool partially the high pressure liquid refrigerant before the refrigerant enters the traditional expansion device immediately prior to the indoor evaporator.
