Abstract

The invention discloses an air conditioner compressor control method and system, and is applied to an automobile with a double-air-conditioner system. The air conditioner compressor control method comprises the following steps of: detecting the states of a front air conditioner and a rear air conditioner in real time; and when one air conditioner is started and the other air conditioner is shut down, controlling an air conditioner compressor to circularly execute an on-off control strategy, wherein the on-off control strategy is that on-off circulation of a preset frequency is executed after the air conditioner compressor is operated for first preset time, the on-off circulation is that the air conditioner compressor is started for third preset time after the air conditioner compressor isshut down for second preset time, and the first preset time is greater than the total time of on-off circulation execution of the preset frequency. By use of the air conditioner compressor control method, the air conditioner compressor is controlled to circularly execute the on-off control strategy to prevent lubricating oil from being accumulated in a non-started air conditioner evaporator and anair conditioner pipeline, the oil return of the air conditioner compressor is obviously eliminated on a premise that cost is not increased, and the working reliability of the compressor is enhanced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an air-conditioning compressor control method and system. Background technique [0002] With the development of the automobile manufacturing industry, the research on automobile air-conditioning technology has also been valued by the industry. Automobile air-conditioning compressor is the heart of automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. [0003] Many current MPVs and seven-seat SUVs use dual air-conditioning systems, that is, dual evaporator systems. When the air conditioner compressor is working, the lubricating oil and refrigerant are mixed and circulated in the entire circuit composed of the air conditioner compressor, pipeline, condenser and evaporator. [0004] In a dual air conditioner system, it often happens that the blower of the front air conditioner works normally, but the blower of the rear ...
