An indirect reversible air conditioning heat pump system of an electric vehicle and a method of operation are provided. The method comprises: a first refrigerant fluid circuit comprising, in the flow direction of the refrigerant fluid: a compressor 1, a first two-fluid heat exchanger 3, a high-pressure liquid drying tank 11, a first expansion valve 5, and a first heat exchanger 6 for passing through by an external air flow of the vehicle; the system further comprises a first internal heat exchanger 12, a second expansion valve 13 and a second two-fluid heat exchanger 16. And a second heat transfer fluid circuit in which a heat transfer fluid flows. The passenger compartment can be rapidly heated, heat loss is reduced, the heat recycling rate is increased, the pipeline is simple, and the cost is low.

    本发明提供一种电动车辆的间接可逆空调热泵系统和操作方法。该方法包括:第一制冷剂流体回路,其在所述制冷剂流体的流动方向上包括:压缩机1、第一双流体热交换器3、高压液体干燥罐11、第一膨胀阀5以及用于被车辆的外部空气流穿过的第一热交换器6;还包括:第一内部热交换器12、第二膨胀阀13和第二双流体热交换器16;第二传热流体回路,传热流体在其中流动。本发明能够快速为乘员舱升温,降低热量损失、提高热量回收利用率且管路简单成本低。
