The invention provides an indirect reversible multi-steam air conditioner heat management system of an electric vehicle and an operation method. The first refrigerant fluid loop comprises a compressor, a first two-fluid heat exchanger, a high-pressure liquid drying tank, a first expansion valve, a first heat exchanger and a first stop valve in the flowing direction of refrigerant fluid; the first heat exchanger is used for being penetrated by external air flow of the vehicle; the second heat exchanger is used for being penetrated by internal air flow of the vehicle and is arranged in a front cabin of the passenger cabin; the third expansion valve and the second double-fluid heat exchanger are arranged in parallel with the second expansion valve and the second heat exchanger; the fourth expansion valve and the third heat exchanger are arranged in a rear compartment of a passenger compartment of the vehicle; the temperature of the front cabin and the rear cabin of the passenger cabin can be quickly increased, the power consumption is reduced, and the driving mileage of the automobile is increased. The indirect air conditioner heat management system of the vehicle is few in parts, simple in pipeline and low in system cost.

    本发明提供一种电动车辆的间接可逆多蒸空调热管理系统及操作方法,该系统包括:第一制冷剂流体回路在制冷剂流体的流动方向上包括:压缩机、第一双流体热交换器、高压液体干燥罐、第一膨胀阀、用于被车辆的外部空气流穿过的第一热交换器、第一截止阀、第二膨胀阀以及用于被车辆的内部空气流穿过且设置在乘员舱前舱的第二热交换器;与第二膨胀阀和第二热交换器并联设置的第三膨胀阀和第二双流体热交换器、第四膨胀阀和第三热交换器,第三热交换器设置在车辆的乘员舱的后舱;本发明可以实现快速为乘员舱前舱和后舱升温,且降低耗电量,提升汽车行驶里程。车辆的间接空调热管理系统中的零部件少、管路简单、系统成本低。
