3、与建筑空调相比，汽车空调工作条件更为苛刻，应具有更高的技术性能。车空调系统由制冷系统及电气控制系统两大部件组成。严格说来，还应包括送风系统，但中小型汽车中，空调的送风任务大多由蒸发箱直接完成的。制冷系统由压缩机、冷凝器、储液干燥器、膨胀阀、蒸发器、风机、进风罩及制冷管道组成。对于全空调结构（指包括冷、暖、通风），则与蒸发器并列一个热交换器（暖风芯子），起采暖作用。采暖以发动机冷却水为热源。制冷循环包括压缩过程、冷凝过程、膨胀过程和蒸发过程。系统通过执行元件不断地对暖风电机转速、出风温度、送风方式及压缩机工作状况等进行调节，从而使车内温度、空气流动状况等始终保持在驾驶员设定的水平
4、上。在使用与维护汽车空调时，应该了解一些注意事项和常识，会进行制冷剂加注操作，能应用常用的诊断方法分析故障。关键词：汽车空调制冷系统加注制冷剂故障检修日常维护AbstractAutomobileAirConditioningisachievedbyartificiallycreatingasuitableenvironmentonthehumanbody.Bytheautomotiveairconditioningrefrigerationsystems,heatingsystems,ventilationsystems,operationcontrolsystems,anda
