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 conditioner is high in energy consumption and a vehicle-mounted battery is short in service life. In order to achieve the purpose, the vehicle-mounted air conditioning unit comprises an in-vehicle unit, an out-vehicle unit and a refrigerant circulation loop arranged between the in-vehicle unit and the out-vehicle unit, the out-vehicle unit comprises a machine shell and an out-vehicle draught fan, a heat exchange channel is formed in the machine shell, and an air outlet, a first air inlet and a second air inlet are further formed in the machine shell; the air outlet is communicated with one end of the heat exchange channel, the second air inlet is located in an airflow path in the vehicle running process, and one of the first air inlet and the second air inlet can be selected to be communicated with the other end of the heat exchange channel. The time for switching the state that the first air inlet communicates with the heat exchange channel to the state that the second air inlet communicates with the heat exchange channel can be determined according to the temperature in the vehicle, energy consumption is effectively reduced through air passing through the machine shell, 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能耗高、车载电池寿命短的问题。为此目的,本发明的车载空调机组包括车内机、车外机以及设置在车内机和车外机之间的冷媒循环回路,车外机包括机壳和车外风机,机壳中形成有换热通道,机壳上还设置有出风口、第一进风口和第二进风口,出风口与换热通道的一端相连通,第二进风口位于车辆行驶过程中的气流路径上,第一进风口和第二进风口能择一与换热通道的另一端相连通,并基于此,本发明能够根据车内温度确定由第一进风口与换热通道连通的状态切换至第二进风口与换热通道连通的状态的时机,利用经过机壳的空气有效降低能耗,保证车载电池的使用寿命。
