The invention relates to a heat pump air conditioning system and a vehicle. The heat pump air-conditioning system comprises a refrigerant subsystem, the refrigerant subsystem comprises a compressor, a reversing valve set, a front air-conditioning box body, a first throttling component and an outside-vehicle heat exchanger which are connected through a refrigerant pipeline, and the first heat exchanger is arranged in the front air-conditioning box body; the reversing valve group is provided with four connecting ports, the first connecting port is connected with an air outlet of the compressor, the second connecting port is connected with the first heat exchanger, the third connecting port is connected with the external heat exchanger, and the fourth connecting port is connected with an air return port of the compressor; the reversing valve group is arranged in the refrigerant subsystem, and the flow direction of the refrigerant in the refrigerant subsystem can be switched by utilizing the reversing valve group, so that not only can the refrigerant subsystem be utilized to refrigerate the passenger compartment, but also the refrigerant subsystem can be utilized to heat the passenger compartment; the requirements of different modes of heating and refrigerating are met at the same time through the refrigerant circulation loop, the system is simplified, and the cost is greatly reduced.
本公开涉及一种热泵空调系统及车辆。该热泵空调系统包括制冷剂子系统,制冷剂子系统包括通过制冷剂管路连接的压缩机、换向阀组、前空调箱体、第一节流部件和车外换热器,前空调箱体内设置第一换热器;换向阀组具有四个连接口,其中第一连接口连接压缩机的出气口,第二连接口连接第一换热器,第三连接口连接车外换热器,第四连接口连接压缩机的回气口;通过在制冷剂子系统中设置换向阀组,可以利用换向阀组切换制冷剂在制冷剂子系统中的流向,如此不仅可以利用制冷剂子系统对乘员舱进行制冷,还可以实现利用制冷剂子系统对乘员舱进行制热;通过制冷剂循环回路同时实现制热和制冷不同模式的需求,简化系统,也大大降低了成本。
