课题名称汽车空调系统常见故障与维护摘要摘要根据汽车空调的特点,介绍汽车空调的日常使用注意事项、和检修注意事项。对汽车售后服务维修以及学员有指导意义。受整车控制单元 VCU 控制。压缩机是空调制冷系统制冷剂循环的动力。压缩机的故障有机械故障和电气系统故障，电气系统故障又分为高压电故障和低压电控制系统故障，压缩机的高压上电受到低压电控制。空调压缩机高压电不能上电，无法正常工作，往往是由于低压控制系统的故障引起的；因此，空调压缩机的电气故障诊断重点从低压电路控制系统着手。当然压缩机的故障诊断关系到高压电，从业者一定要有相应的高压从业资格证，遵守高压维修的相关规范，才能确保人身安全。关键词：汽车、空调、注意事项、维护保养、故障检修I┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊ABSTRACTABSTRACT：According to the characteristics of automobile air conditioning,this paper introduces the matters needing attention in daily use and maintenance of automobile air conditioning.It has guiding significance for the after-sales service maintenance of automobiles and trainees.It is controlled by vehicle control unit VCU.Compressor is the power of refrigerant cycle in air conditioning refrigeration system.Compressor faults include mechanical faults and electrical system faults.Electrical system faults can be divided into high-voltage electrical faults and low-voltage control system faults.Compressor high-voltage power-up is controlled by low-voltage electrical faults.The high-voltage power of air-conditioning compressor can not be turned on and can not work normally,which is often caused by the fault of low-voltage control system.Therefore,the electric fault diagnosis of air-conditioning compressor focuses on the low-voltage circuit control system.Of course,the fault diagnosis of compressor is related to high-voltage electricity.The practitioner must have the corresponding high-voltage qualification certificate and abide ...
