air conditioning system, in particular for motor vehicles, heating and / or cooling a passenger compartment.

摘要

The air-conditioning unit has a compressor which can be used simultaneously for at least 2 parallel air-conditioning circuits, one of which is used for cooling the air supplied to the automobile passenger compartment and another of which is used for heating the air supplied to the passenger compartment. The high pressure coolant flow is divided into 2 partial streams (7,9) on the high pressure side (3) of the compressor via a valve (5), one partial stream fed through a gas cooler (11) the other fed through a heat exchanger (39).
