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.
