Refrigeration system has an intermediate heat exchanger between the condenser and refrigerant expansion unit to heat the refrigerant vapour

摘要

A compressor (12) passes refrigerant gas through a cooling heat exchanger (14) and one side (22) of an intermediate heat exchanger (16) to an expansion system (18) cooling an evaporator (20) entirely filled with vapor. Gas returning to the compressor is heated in the intermediate heat exchanger (24).
