ABSTRACT:
The efficiency of refrigeration systems operating on the vapor compression cycle and employing suction line heat exchangers is increased by introducing refrigerant into the lower pressure side of the suction line heat exchanger at a quality less than 1 and introducing refrigerant that has passed through the low pressure side of the suction line heat exchanger into the compressor inlet at a quality that is equal to 1.
