The embodiment of the invention discloses an automobile air-conditioning system and a control method thereof. The automobile air-conditioning system comprises an air conditioning controller and a vehicle-mounted air conditioner. At least one air inlet of the vehicle-mounted air conditioner is communicated with at least one air inlet formed in a passenger cabin door through a vehicle body air duct.The air conditioner controller is used for detecting an air conditioner control signal and adjusting an output mode switching signal according to the air conditioner control signal; and the vehicle-mounted air conditioner is electrically connected with the air conditioner controller and is used for receiving a mode switching signal and controlling the vehicle-mounted air conditioner to switch between an inner circulation mode and an outer circulation mode according to the mode switching signal. According to the technical scheme of the embodiment of the invention, a mode of carrying out air circulation exchange inside and outside the vehicle through the air inlet of the passenger cabin door replaces an existing mode of carrying out air circulation exchange inside and outside the vehicle through the driving cabin rain baffle air inlet channel, so that the influence on the refrigeration performance due to secondary heating of air entering the driving cabin by heat radiation of the transmitter is avoided; meanwhile, due to the fact that the passenger cabin can directly obtain fresh air, the air renewal efficiency in the passenger cabin is improved.

    本发明实施例公开了一种汽车空调系统及其控制方法。该汽车空调系统包括空调控制器和车载空调;车载空调的至少一进风口与设置于客舱车门的至少一进风口,通过车身本体风道连通;空调控制器,侦测空调控制信号,根据空调控制信号调节输出模式切换信号;车载空调,与空调控制器电连接,接收模式切换信号,根据模式切换信号控制车载空调进行内循环模式与外循环模式的切换。本发明实施例的技术方案通过客舱车门的进风口进行车内外空气循环交换的方式,替换现有的通过驾舱挡雨板进气通道进行车内外空气循环交换的方式,避免了发送机热辐射对驾舱进入的空气进行二次加热而影响制冷性能,同时由于客舱可以直接获得新风,提高了客舱内的空气更新效率。
