Air conditioning system for e.g. cooling supply air for vehicle`s internal space, has heat exchanger with outlet, where outlet and inlet of low pressure strands of internal heat exchanger are connected with connecting line having valve

摘要

The system (10) has a heat exchanger (20) with a strand (28) connected with a high pressure strand (24) of an internal heat exchanger (14) by a connecting line (78), and a valve (44) i.e. solenoid valve, in a connecting line (22). A valve (60) i.e. check valve provided in a connecting line (58) is connected to a connecting line (38) between an expansion organ (18) and a strand (30) of the exchanger (20). An outlet of the exchanger (14) and an inlet of low pressure strands (26) of an internal heat exchanger (16) are connected with a connecting line (66) having a valve (64) i.e. three-way valve.
