The present disclosure relates to a vehicle HVAC system, the system including: a compressor; an internal condenser provided on the downstream side of the compressor; a water-cooled heat exchanger disposed on a downstream side of the internal condenser and configured to transfer heat between the refrigerant and cooling water circulating in the cooling water system; a refrigerant heat exchanger disposed on an upstream side of the compressor and configured to transfer heat between the refrigerant discharged from the water-cooled heat exchanger and the refrigerant discharged from the internal condenser; and a first control valve disposed between the water-cooled heat exchanger and the internal condenser and configured to control a flow of refrigerant among the internal condenser, the water-cooled heat exchanger, and the refrigerant heat exchanger.
本公开涉及一种车辆HVAC系统,该系统包括:压缩机;内部冷凝器,设置在压缩机的下游侧;水冷式热交换器,设置在内部冷凝器的下游侧,并被构造为在制冷剂和在冷却水系统中循环的冷却水之间传递热量;制冷剂热交换器,设置在压缩机的上游侧,并被构造为在从水冷式热交换器排出的制冷剂和从内部冷凝器排出的制冷剂之间传递热量;以及第一控制阀,设置在水冷式热交换器和内部冷凝器之间,并被构造为控制制冷剂在内部冷凝器、水冷式热交换器和制冷剂热交换器之间的流动。
