The invention relates to a heat pump air conditioning system and a vehicle, the system comprises a compressor, an outdoor heat exchanger, a first gas-liquid separation device, a first heat exchanger, a first expansion valve and an indoor evaporator, an outlet of the compressor is connected with a first opening of the outdoor heat exchanger, and a second opening of the outdoor heat exchanger is connected with an inlet of the first gas-liquid separation device; a liquid outlet of the first gas-liquid separation device is connected with a first refrigerant inlet of the first heat exchanger, a first refrigerant outlet of the first heat exchanger is connected with an inlet of the indoor evaporator through the first expansion valve, and an outlet of the indoor evaporator is connected with a second refrigerant inlet of the first heat exchanger. A second refrigerant outlet of the first heat exchanger is connected with an inlet of the compressor. A liquid refrigerant flows out of a liquid outlet of the first gas-liquid separation device, so that the supercooling degree of the refrigerant flowing out of the outdoor heat exchanger in a refrigeration mode can be improved; in addition, the refrigerant can release heat twice in the outdoor heat exchanger and the first heat exchanger, and the supercooling degree of the refrigerant entering the indoor evaporator is further improved.
本公开涉及一种热泵空调系统和车辆,该系统包括压缩机、室外换热器、第一气液分离装置、第一换热器、第一膨胀阀以及室内蒸发器,压缩机的出口与室外换热器的第一口连接,室外换热器的第二口与第一气液分离装置的入口连接,第一气液分离装置的出液口与第一换热器的第一冷媒入口连接,第一换热器的第一冷媒出口经由第一膨胀阀与室内蒸发器的入口连接,室内蒸发器的出口与第一换热器的第二冷媒入口连接,第一换热器的第二冷媒出口与压缩机的入口连接。第一气液分离装置的出液口流出液态冷媒,能提高制冷模式下从室外换热器流出的冷媒的过冷度;此外冷媒能够在室外换热器和第一换热器中进行两次放热,进一步提高进入室内蒸发器的冷媒的过冷度。
