Abstract
With the rapid development of the automobile industry, the automobile air conditioning system has its performance and reliability. However, in the actual use process, the automobile air conditioning system often has a series of problems such as poor refrigeration effect, electrical system failure and mechanical parts damage, which seriously affect the passenger comfort experience and driving safety. The failure of the air conditioning system may also lead to an increase in vehicle energy consumption, which will affect the economy of the vehicle. This study focuses on the optimization of fault diagnosis and maintenance of automobile air conditioning system. Firstly, we summarize the basic principles of automobile air conditioning system, including the composition and functions of refrigeration system, heating system, ventilation system and control system. Then, the main causes of the air conditioning system failure, such as mechanical failure, electrical fault and refrigerant problems. On this basis, the common methods of fault diagnosis, such as direct inspection, instrument detection and system pressure test. Further, this study addresses the importance of fault diagnosis of automotive air conditioning systems, including its impact on driving safety, passenger comfort, and vehicle economy. In view of the common problems such as poor refrigeration effect, electrical system failure and mechanical parts damage, the corresponding maintenance optimization countermeasures are proposed, including refrigeration effect optimization, electrical system maintenance strategy, maintenance and replacement of mechanical parts and preventive maintenance measures. Through this study, it aims to provide scientific basis and practical guidance for the fault diagnosis and maintenance of automobile air conditioning system, in order to improve maintenance efficiency, reduce maintenance cost, and then improve driving safety and passenger comfort.
