The invention relates to the technical field of vehicle-mounted air conditioners, particularly provides a vehicle-mounted air conditioning unit and a control method thereof, and aims to solve the problems that an existing vehicle-mounted air conditioning unit is high in energy consumption and short in service life of a vehicle-mounted battery. Therefore, a condenser, a throttling component, an evaporator and a compressor are arranged on a refrigerant circulation loop of the vehicle-mounted air conditioning unit, the vehicle external unit comprises a machine shell and a vehicle external fan, an air outlet, a first air inlet and a second air inlet are formed in the machine shell, and the second air inlet is located in an airflow path in the vehicle running process. The air outlet is communicated with one end of the heat exchange channel in the machine shell, one of the first air inlet and the second air inlet is arranged to be communicated with the other end of the heat exchange channel, and on the basis, the communication state of the first air inlet and the heat exchange channel and the communication state of the second air inlet and the heat exchange channel are controlled according to the displacement speed of the vehicle. Air passing through the machine shell in the running process of a vehicle is fully utilized to conduct heat exchange on the condenser, energy consumption is reduced, and the service life of a vehicle-mounted battery is guaranteed.

    本发明涉及车载空调技术领域,具体提供一种车载空调机组及其控制方法,旨在解决现有车载空调机组能耗高、车载电池寿命短的问题。为此,本发明的车载空调机组的冷媒循环回路上设置有冷凝器、节流构件、蒸发器和压缩机,车外机包括机壳和车外风机,机壳上设置有出风口、第一进风口和第二进风口,第二进风口位于车辆行驶过程中的气流路径上,出风口与机壳中的换热通道的一端相连通,第一进风口和第二进风口设置成能够择一与换热通道的另一端相连通,并基于此,本发明根据车辆的位移速度控制第一进风口和第二进风口与换热通道的连通状态,以充分利用车辆行驶过程中经过机壳的空气对冷凝器进行换热,降低能耗,保证车载电池的使用寿命。
