The invention provides a vehicle low-energy-consumption heat management system which comprises an air conditioner cooling loop, a heating loop, an electric drive cooling loop and a battery heat management loop. A three-way valve A is arranged among a water-cooled condenser of the air conditioner cooling loop, the heating loop and the electric drive cooling loop, and the water-cooled condenser is connected into the heating loop in a first mode or connected into the electric drive cooling loop in a second mode by controlling the three-way valve A to be switched between the first mode and the second mode. The water-cooled condenser can be used through multiple loops, the power consumption of a compressor is reduced in a high-temperature environment, and rapid cooling is achieved; and a passenger compartment is heated by utilizing the heat of the compressor in a low-temperature environment; cooling and heating of the whole electric vehicle, cooling of a driving battery and heating of the driving battery are considered, the comfort of a user and the power performance of the whole vehicle are ensured, and power consumption of the heat management system is reduced.

    一种车辆低能耗热管理系统,包括空调降温回路、采暖回路、电驱冷却回路和电池热管理回路。在空调降温回路的水冷冷凝器与采暖回路和电驱冷却回路之间设置一个三通阀A,通过控制三通阀A在第一模式和第二模式之间切换,使水冷冷凝器在所述第一模式下接入采暖回路,或在所述第二模式下接入电驱冷却回路。本发明可以通过多回路使用水冷冷凝器,在高温环境下降低压缩机功耗,实现快速降温;在低温环境下利用压缩机热量给乘员舱加热。既兼顾电动车整车降温、采暖、驱动电池的冷却、驱动电池的加热,确保用户的舒适性、整车动力性,又降低了热管理系统耗电。
