The invention relates to a heat pump air conditioning system and a vehicle, the heat pump air conditioning system comprises a compressor, an outdoor heat exchanger, a first heat exchanger, a first expansion valve and an indoor evaporator, an outlet of the compressor is connected with an inlet of the outdoor heat exchanger, and an outlet of the outdoor heat exchanger 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, an outlet of the indoor evaporator is connected with a second refrigerant inlet of the first heat exchanger, and a second refrigerant outlet of the first heat exchanger is connected with an inlet of the compressor. The first heat exchanger is arranged, the refrigerant can release heat twice in the outdoor heat exchanger and the first heat exchanger in the refrigeration mode, the supercooling degree of the refrigerant entering the indoor evaporator is improved, and therefore the problem that the heat release amount of the refrigerant in the outdoor heat exchanger is limited in the high-temperature environment is solved.
本公开涉及一种热泵空调系统和车辆,该热泵空调系统包括压缩机、室外换热器、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入口连接,室外换热器的出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。通过设置第一换热器,并在制冷模式下使冷媒能够在室外换热器和第一换热器中进行两次放热,提高进入室内蒸发器的冷媒的过冷度,从而解决在高温环境下冷媒在室外换热器中放热量有限的问题。
