Circuit arrangement for refrigeration and/or heating of motor car, has outer heat exchanger that is connected over valve and divided into two separate flow-through portions

摘要

The circuit arrangement (301) comprises a compressor (200), an evaporator (iv), a sub-cooler (SC) and a capacitor (IC) in a refrigerant circuit. The first circuit is connected with evaporator and the sub-cooler. The outer heat exchanger (302) is connected over valve (25). The outer heat exchanger is divided into two separate flow-through portions (A1,A2). A branch line is connected between evaporator and sub-cooler.
