Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an air conditioner condenser fan control circuit, a device and an automobile. Background technique [0002] In the existing automobile air-conditioning system, when the power switch, windshield switch and AC switch are turned on, the condenser fan and compressor start to work, and the refrigerant (R134a) flows through the refrigerant cycle of the evaporation core in the bellows, and passes through the compressor, condenser, The low-temperature liquid refrigerant formed by the action of the throttling tube and the like absorbs the heat of the surrounding air to achieve refrigeration. [0003] The existing air conditioner control circuit is composed of a power supply control circuit, a blower control circuit, an electromagnetic clutch control circuit, and a temperature control circuit. The relay can be turned on. Blower control circuit: control the speed of th...
