The invention discloses an electric vehicle air conditioning heat pump system adopting double bypass valves and an electronic expansion valve. The system comprises a compressor, a first indoor heat exchanger, a second indoor heat exchanger, a gas-liquid separator and an outdoor heat exchanger, wherein the compressor is connected to the outdoor heat exchanger through a first electromagnetic valve,the outdoor heat exchanger is connected to the first indoor heat exchanger through a thermostatic expansion valve with a cut-off function, the first indoor heat exchanger is connected to the compressor through the gas-liquid separator so as to form a refrigerating loop, the compressor is further connected to the second indoor heat exchanger, the second indoor heat exchanger is connected to the outdoor heat exchanger through the electronic expansion valve, and the outdoor heat exchanger is connected to the compressor through a second electromagnetic valve and the gas-liquid separator so as to form a heating loop. According to the electric vehicle air conditioning heat pump system adopting the double bypass valves and the electronic expansion valve, the energy consumption of an air conditioning system of an electric vehicle can be effectively reduced, and the endurance mileage of the vehicle can be guaranteed.

    本发明公开了一种电动汽车及采用双旁通阀及电子膨胀阀的电动汽车空调热泵系统,该系统包括压缩机、第一及第二室内换热器、气液分离器和室外换热器,压缩机经第一电磁阀连接至室外换热器,室外换热器经具有截止功能的热力膨胀阀连接至第一室内换热器,第一室内换热器经气液分离器连接至压缩机,从而形成制冷回路,压缩机还连接至第二室内换热器,第二室内换热器经电子膨胀阀连接至室外换热器,室外换热器经第二电磁阀及气液分离器连接至压缩机,从而形成制热回路。根据本发明的电动汽车及采用双旁通阀及电子膨胀阀的电动汽车空调热泵系统,能够有效降低电动汽车的空调系统的能耗并确保车辆的续航里程。
