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.

Refrigeration system

A heat pump system includes a compressor ( ), first and second heat exchangers ( ) and a module ( ) hydraulically interposed between the compressor ( ) and the first and second heat exchangers ( ). The module includes a heat exchanger component ( ) together with an accumulator ( ), an expansion device ( ) and a four-way valve ( ) for controlling operation of the system.
