The invention relates to a solar auxiliary heating type electric automobile heat pump air conditioning system, a working method and an automobile. The system comprises a compressor, a four-way valve, an indoor heat exchanger, a power battery, a plate heat exchanger, a water pump, a power motor, an outdoor radiator, a roof photovoltaic panel, a gas-liquid separator, a stop valve, an electronic expansion valve A, an electronic expansion valve B and an electronic expansion valve C; the radiating surface of the roof photovoltaic panel is exposed or hidden, when the radiating surface is in an exposed state, cooling liquid is heated through solar radiation, and when the radiating surface is in a hidden state, convection heat exchange is formed between the radiating surface and air; the photovoltaic panel located at the roof position of the electric automobile is used for heating cooling liquid, the heat absorption temperature of a low-temperature refrigerant is increased, the auxiliary heating effect on the heat pump air conditioning system is achieved, a heat management system is optimized, low-temperature heating energy consumption is reduced, and the endurance mileage is increased; therefore, the problems that an electric automobile heat pump air conditioning system is low in heating energy efficiency and low in heating speed are solved.

    本发明涉及一种太阳能辅热式电动汽车热泵空调系统、工作方法及汽车;系统包括压缩机、四通阀、室内换热器、动力电池、板式换热器、水泵、动力电机、室外散热器、车顶光伏板、气液分离器、截止阀、电子膨胀阀A、电子膨胀阀B、电子膨胀阀C;车顶光伏板的辐射面外显或者隐藏,辐射面处于外显状态时,通过太阳辐射给冷却液加热,辐射面处于隐藏状态时,与空气形成对流换热;本发明利用位于电动汽车车顶位置的光伏板对冷却液进行加热,提高低温冷媒的吸热温度,对热泵空调系统起到辅助加热的作用,优化热管理系统,降低低温采暖能耗,增加续航里程,从而解决电动汽车热泵空调系统制热能效比较低和制热速度慢的问题。
