The invention belongs to the technical field of automobile air conditioners, and discloses an air conditioner condenser fan control circuit and device and an automobile. The air conditioner condenserfan control circuit comprises an oscillation circuit, a rectification circuit and a rotating speed control circuit. The oscillation circuit receives a pressure electric signal output by an air conditioner refrigeration system and outputs sine alternating current to the rectification circuit according to the pressure electric signal; the rectification circuit rectifies the sine alternating currentand then outputs direct current to the rotating speed control circuit; and the rotating speed control circuit controls the rotating speed of the condenser fan according to the direct current. The rotating speed of the fan is determined according to the pressure of the air conditioner refrigeration system, so that energy saving of the condenser fan is realized; and meanwhile, the fan of the air conditioner condenser is independently controlled, so that excessive instantaneous current caused by synchronous starting of the compressor and the condenser fan is avoided, and the problems of energy waste and excessive instantaneous current of an air conditioner system loop due to synchronous working or stopping of the compressor and the condenser fan of an existing air conditioner control circuitare solved.

    本发明属于汽车空调技术领域,公开了一种空调冷凝器风扇控制电路、装置及汽车。该空调冷凝器风扇控制电路包括震荡电路、整流电路以及转速控制电路;其中,震荡电路接收空调制冷系统输出的压力电信号,并根据压力电信号输出正弦交流电至整流电路;整流电路对正弦交流电进行整流后输出直流电至转速控制电路;转速控制电路根据直流电控制冷凝器风扇的转速。本发明中根据空调制冷系统的压力高低来确定风扇的转速,实现冷凝风机节能,同时单独对空调冷凝器风扇进行控制,避免压缩机与冷凝风机同步启动造成瞬时电流过大,解决了现有空调控制电路压缩机和冷凝风机同步工作或停止存在能量浪费以及空调系统回路瞬时电流过大的问题。
