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.

1. For straight cool and refrigeration systems, a low pressure suction side refrigerant to liquid refrigerant heat exchanger located in a refrigeration circuit, comprising in combination: a low pressure suction side refrigerant portion of the heat exchanger in fluid communication in the refrigeration circuit between an outlet of an evaporator and an inlet of the compressor and a liquid refrigerant portion of the heat exchanger in fluid communication in the refrigeration circuit between an outlet of the condenser and an inlet to a thermostatic expansion device for the evaporator; a sensor and an external equalizer tube being located downstream of the suction, low pressure, side of the heat exchanger on a line connecting the heat exchanger outlet to the compressor inlet; the refrigerant flowing through each portion of the heat exchangers so that a superheat and flash gas loss regions of the evaporator are effectively eliminated, allowing for a greater refrigerant mass flow, and greater refrigeration capacity in the evaporator, as well as allowing for a greater system efficiency.
