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ABSTRACTABSTRACT：Accordingtothecharacteristicsofautomobileairconditioning,thispaperintroducesthemattersneedingattentionindailyuseandmaintenanceofautomobileairconditioning.Ithasguidingsignificancefortheafter-salesservicemaintenanceofautomobilesandtrainees.ItiscontrolledbyvehiclecontrolunitVCU.Compressoristhepowerofrefrigerantcycleinairconditioningrefrigerationsystem.Compressorfaultsincludemechanicalfaultsandelectricalsystemfaults.Electricalsystemfaultscanbedividedintohigh-voltageelectricalfaultsandlow-voltagecontrolsystemfaults.Compressorhigh-voltagepower-upiscontrolledbylow-voltageelectricalfaults.Thehigh-voltagepowerofair-conditioningcompressorcannotbeturnedonandcannotworknormally,whichisoftencausedbythefaultoflow-voltagecontrolsystem.Therefore,theelectricfaultdiagnosisofair-conditioningcompressorfocusesonthelow-voltagecircuitcontrolsystem.Ofcourse,thefaultdiagnosisofcompressorisrelatedtohigh-voltageelectricity.Thepractitionermusthavethecorrespondinghigh-voltagequalificationcertificateandabidebytherelevantnormsofhigh-voltagemaintenance,soastoensurepersonalsafety.KEYWORDS：Automobile,AirConditioning,Cautions,MaintenanceTroubleshooting目录目录1汽车空调系统的特点......................................................................................................................................51.1汽车空调的特点..........................................................................................................................................51.2典型汽车空调系统的结构工作原理与特点..............................................................................................52空调系统的保养..............................................................................................................................................72.1汽车空调使用注意事项..............................................................................................................................72.2车空调保养..................................................................................................................................................72.2.1全面检查空调..........................................................................................................................................72.2.2注意空调的清洗......................................................................................................................................72.2.3定期开启空调..........................................................................................................................................82.3汽车空调系统故障的检修..........................................................................................................................83汽车空调系统典型故障...
