The invention discloses an energy storage type automobile heat pump air conditioning system and a working method thereof. The energy storage type automobile heat pump air conditioning system comprisesa compressor and a power supply which supplies power to the compressor; an intermediate heat exchanger, a first expansion valve, an outdoor heat exchanger, a second expansion valve and an evaporatorare sequentially connected between an outlet and an inlet of the compressor. A stop valve is further connected between the inlet of the second expansion valve and the outlet of the evaporator througha pipeline; the intermediate heat exchanger is further connected with a water pump connected to an inlet of a three-way valve, a main outlet of the three-way valve is connected to a heater connected to an inlet of the intermediate heat exchanger, and an internal combustion engine is connected between a secondary outlet of the three-way valve and an inlet of the heater. The storage battery pack isadditionally arranged in the oil-fired automobile, and the functions of refrigerating, heating and engine preheating can still be achieved in the flameout state of an automobile engine. Refrigeratingand heat pump heating functions can be achieved only through two expansion valves and one stop valve in the refrigerant circulating system, and a system loop is simple.

    本发明技术方案公开了一种蓄能式汽车热泵空调系统及其工作方法,包括压缩机;向压缩机供电的电源;压缩机的出口至进口之间分别依次连接中间换热器、第一膨胀阀、室外换热器、第二膨胀阀和蒸发器;第二膨胀阀的进口与蒸发器的出口之间通过管路还连接有截止阀;中间换热器还连接有水泵,水泵连接至一三通阀的进口,三通阀的主出口连接至加热器,加热器连接至中间换热器的进口,三通阀的次出口与加热器的进口之间连接内燃机引擎。本发明通过在燃油汽车中加入蓄电池组,可在汽车发动机熄火状态下仍能实现制冷、制热和发动机预热的功能。制冷剂循环系统中仅通过两个膨胀阀和一个截止阀即可实现制冷和热泵制热功能,系统回路简单。
