Absrtact: with the development of automobile and the comfort demand of consumers, the air conditioning system is equipped. The main function of the air conditioning system is to control the temperature in the car. In addition to its heating and cooling control functions, it also plays the role of dehumidification, and helps to remove the frost, ice and condensation water mist in the window and other visual obstacles. This paper makes a simple analysis of the common faults of automobile air conditioning system, and gives some simple diagnosis methods through examples: automobile air conditioning fault analysis, diagnosis and maintenance automobile air conditioning system provides the functions of refrigeration, heating, defrosting, air filtration and humidity control for the automobile, so as to make the passengers more comfortable. In this paper, the basic components of the air conditioning system are described in detail, in order to deepen the understanding of the research content, and deepen the research and analysis of the automotive air conditioning refrigeration device. Automobile air conditioning system is a device which can cool, heat, change air and purify the air in the car. It can provide comfortable riding environment for passengers, reduce the fatigue strength of drivers and improve driving safety. Air conditioning device has become a sign to measure whether the car functions well. The air conditioning system is generally composed of the following five systems: the refrigeration system cools or dehumidifies the air in the car or the fresh air entering the car from the outside to make the air in the car cool and comfortable. _The heating system is mainly used for heating, heating the air inside the car or the fresh air entering the car from the outside to achieve heating and dehumidification. _X000b ﹣ the ventilation system absorbs the fresh air from the outside into the car room for ventilation and air exchange. At the same time, ventilation also plays a good role in preventing the windshield from fogging. _The air purification system can remove the dust, odor, smoke and toxic gas in the air of the car, and make the air in the car clean. _X000b ﹐ the control system controls the temperature and pressure of the refrigeration and heating system, and controls the temperature, air volume and flow direction of the air in the car room to ensure the normal operation of the air conditioning system. At the same time, in the whole air-conditioning system, the compressor is the pressure source compressor of the medium running in the pipeline. When the sensor installed in the outlet seal of the evaporator senses that the temperature of the air is not low enough, it will close the magnetic clutch of the compressor through the circuit, so that the compressor runs with the engine to achieve refrigeration.<br>Key words: automobile air conditioning fault analysis, diagnosis and maintenance<br>
