1、摘要随着中国的发展，人们生活水平日益提高和汽车行业的迅猛发展，汽车开始走进千家万户。人们一贯追求汽车的安全性、可靠性的同时，如今也更加注重对汽车舒适性的要求。因而，空调系统作为现代轿车的基本配备，成为汽车的一个重要的舒适性要求，也就成了必然。近年來环保和能源问题成为世界关注的焦点以为成为汽车业发展的关键因素各种替代能源动力车的岀现为汽车空调业提岀了新的课题和挑战。汽车空调技术是随着汽车的普及和高新技术的应用而发展起来的。其发展经历了有低级到高级，由单一功能到多功能的五个阶段：即单一取暖阶段、单一冷气阶段、冷暧一体化阶段

2、、自动控制阶段、微机控制阶段。作为汽车空调系统的电路控制方面也再不段的更新改进，同时，我国汽车空调的安装随着汽车业的发展以达到100%的普及性，空调已成为现代汽车的一向基木配备。给汽车空调的使用与维修问题带来新的挑战。论文最后以汽车空调故障检修的方法，对汽车空调系统的再深入探讨，以达到对汽车空调系统的了解，并运用在实际工作中。关键词：汽车空调压缩机检修ABSTRACTInthewakeofdevelopmentinChina,thelivingstandardofpeoplehavebeenimprovedaccord
