Abstract

The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner control system. The automobile air conditioner control system comprises an air conditioner controller, a first relay, a second relay, a third relay, a fourth relay, an air conditioner pressure switch, a compressor, a condenser fan and an ECU. A low-potential signal can be synchronously output through a first terminal and a second terminal of the air conditioner controller, so that the condenser fan and the compressor synchronously work; and the problem that an existing air conditioner system is poor in air conditioner refrigerating effect during engine idling is solved, frequent tripping of the pressure switch is avoided, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner control system. Background technique [0002] With the continuous development of automobile technology, drivers have higher and higher requirements for vehicle driving and riding comfort. A comfortable driving environment can effectively protect drivers and passengers, especially in bad weather. Because drivers have a comfortable driving environment, they can relieve long-term driving fatigue and become less irritable, which can effectively reduce accidents Frequency of occurrence. [0003] In the prior art, many cars assemble the air-conditioning condenser with the silicon oil fan of the engine water tank, and use the silicon oil fan to dissipate heat for both the water tank and the condenser at the same time. Under normal circumstances, the fan will not turn on, which will lead to poor heat dissipation of the condenser, a decr...
