摘要

The compressor (3) is part of a circuit with a cooler (4) for carrying heat away from the coolant, an expansion valve (5) and an evaporator (6a,b) for transferring heat to the coolant. The coolant circuit can be operated as a cooling machine and as a heat pump. The coolant compressor has an associated switching valve (2) with at least one connection that is made in one piece with the coolant compressor and/or integrated into its housing (15).
