The invention discloses an automobile air conditioner control circuit, and is characterized in that the automobile air conditioner control circuit comprises an air conditioner ECU, a single chip microcomputer, a control module, a low-pressure maintenance pipeline, a high-pressure maintenance pipeline and a solar cell panel; the output end of the control module is connected with a semiconductor refrigeration and heating module; a negative electrode of the solar cell panel, a negative electrode of a super capacitor, a negative electrode of a storage battery and a solar panel are mounted outsidean automobile roof, and an electric reactor is mounted on the positive electrode of the battery. The electric reactor is mounted at the positive electrode of the battery to eliminate large-current impact on an automobile battery pack caused by abnormality of rear-end equipment, so that the battery pack is protected; meanwhile, a pre-charging circuit is designed, and the situation that high voltageis applied to the variable frequency input end at the moment when an air conditioner is started or suddenly powered on is eliminated through the pre-charging circuit. In addition, a first relay and atravel switch mounted on a bottom plate of the air conditioner provide a guarantee for guaranteeing the life safety of workers when the air conditioner is maintained.

    本发明公开了本发明提供一种汽车空调控制电路,其特征在于:包括空调ECU、单片机、控制模块、低压维修管路、高压维修管路、太阳能电池板,所述控制模块的输出端与半导体制冷和制热模块连接,所述太阳能电池板负极和超级电容负极、蓄电池负极,所述太阳能电池板安装在汽车顶棚外面,所述电池正极安装有电抗器。电池正级安装一个电抗器以消除后端设备的异常而导致的大电流冲击汽车电池组,起保护电池组的功能;本发明同时也设计了一个预充电路,通过预充电路消除了空调在启动或突然上电瞬间将高压施加到变频输入端。除此之外,第一继电器和安装在空调底板上的行程开关为确保工作人员在维修空调时的生命安全提供了保障。
