The HVAC system of the present invention includes a compressor; an internal condenser provided on the downstream side of the compressor; a refrigerant heat exchanger between the internal condenser and the compressor, the refrigerant heat exchanger configured to transfer heat between an expanded refrigerant and an unexpanded refrigerant among the refrigerants discharged from the internal condenser; a water-cooled heat exchanger disposed on a downstream side of the internal condenser and configured to transfer heat between the refrigerant and the coolant circulating in the coolant system; an external heat exchanger disposed on a downstream side of the internal condenser and configured to transfer heat between the refrigerant and ambient air; and a control valve unit configured to control flow of the refrigerant and expansion and/or non-expansion of the refrigerant among the internal condenser, the water-cooled heat exchanger, the external heat exchanger, and the refrigerant heat exchanger.

    本发明的HVAC系统包括压缩机;内部冷凝器,其设置在压缩机的下游侧;制冷剂热交换器,其位于内部冷凝器与压缩机之间,制冷剂热交换器被配置成在从内部冷凝器排出的制冷剂中的膨胀制冷剂与未膨胀制冷剂之间传递热量;水冷式热交换器,其设置在内部冷凝器的下游侧,并且被配置成在制冷剂与在冷却剂系统中循环的冷却剂之间传递热量;外部热交换器,其设置在内部冷凝器的下游侧,并且被配置成在制冷剂与环境空气之间传递热量;和控制阀单元,其被配置成控制在内部冷凝器、水冷式热交换器、外部热交换器和制冷剂热交换器之间的制冷剂的流动以及制冷剂的膨胀和/或非膨胀。
