The invention relates to the field of automobile air conditioners, in particular to an automobile air conditioner based on a heat pump system, which comprises the heat pump system, a high-temperature loop, a low-temperature loop, a high-temperature load, a low-temperature load, a heat recovery unit and a radiator. The heat pump system is sequentially connected to the heat recovery unit, one or more high-temperature loads and the radiator through a high-temperature loop. The heat pump system is connected to one or more low-temperature loads and a heat sink through a low-temperature loop. The invention further provides a method for controlling the temperature of the automobile through the heat pump system. The method comprises a heating mode and a refrigerating mode. By means of the heat recovery unit, the use range of the heat pump at the low temperature of-30 DEG C is widened. The heat pump system greatly increases the driving mileage of the electric vehicle, and is of great significance to the development of the electric vehicle. And meanwhile, the control valve is introduced, so that the vehicle-mounted management system utilizes the same heat pump system to heat or refrigerate the vehicle parts, and the temperature of the vehicle parts can be more accurately controlled.

    本发明涉及汽车空调领域,特别是一种基于热泵系统的汽车空调,包含热泵系统、高温回路、低温回路、高温负载、低温负载、热回收单元和散热器。热泵系统通过高温回路依次连接到热回收单元以及一个或者多个高温负载,以及散热器。热泵系统通过低温回路连接到一个或者多个低温负载,以及散热器。本发明还包含利用热泵系统进行汽车控温的方法,包含制热和制冷两种模式。本发明利用热回收单元,扩大热泵低温‑30℃使用范围。热泵系统大幅提高电动车的行驶里程,对电动汽车的发展有重要意义。同时,本发明引入控制阀,使得车载管理系统利用同一套热泵系统,对车辆部件进行加热或者制冷,从而更能精准的控制车辆部件的温度。
