Cooling circuit for motor vehicle air conditioning system has coolant compressor, liquefier for gaseous coolant from compressor, decompression unit, evaporator and bypass line

摘要

The cooling circuit has a compressor (10) that compresses coolant and outputs gaseous coolant, a liquefier (14) that compresses the gaseous coolant from the compressor, a decompression unit (16) for the liquefied coolant, an evaporator (18) and a bypass line (20) that feeds the gaseous coolant from the compressor directly into the evaporator in a heating mode.
