The invention discloses an air conditioner heat pump system for an electric vehicle which is characterized in that the system has two working modes of a heating mode and a refrigerating mode, and the system comprises a heating loop, a refrigerating loop and a switching valve group. The switching valve group is used for controlling the working mode of the air conditioner heat pump system and switching the current working loop to be any one of the refrigerating loop and the heating loop. The invention further discloses a temperature control method using the air conditioner heat pump system for the electric vehicle. Compared with the prior art, the air conditioner heat pump system for the electric vehicle has the advantages that when the same heating capacity is achieved, the energy consumed by the heat pump system is only about half of that consumed by a PTC heater, the endurance mileage of the electric vehicle in winter can be increased, and the air conditioner heat pump system has important significance on development of the electric vehicle.

    本发明公开了一种电动汽车空调热泵系统,其特征在于,具备制热模式和制冷模式两种工作模式,系统包含制热回路,制冷回路和切换阀组。切换阀组用于控制空调热泵系统的工作模式,切换当前工作回路为制冷回路或者制热回路中的任意一个。本发明还包含一种利用电动汽车空调热泵系统的温度控制方法。本发明涉及的电动汽车空调热泵系统,与现有技术相比具有的优势效果是:在达到同样的制热量时,热泵系统消耗的能源仅为PTC加热器电加热器的一半左右,可以提高电动车冬季的续航里程,对电动汽车的发展有着重要的意义。
