Catalogue of passenger car air conditioning structures and maintenance

This book makes a necessary introduction to the principle, structure and basic theoretical knowledge of bus air conditioning, focusing on the detection, diagnosis and repair of bus air conditioning. The book focuses on the computer-controlled bus air-conditioning system, and comprehensively discusses the characteristics, structure, diagnosis and maintenance methods of these systems. The fault diagnosis and maintenance methods of traditional passenger car air conditioners are also introduced in detail. The book also gives a considerable number of examples of the maintenance of passenger car air conditioners.

The whole book is closely related to practice and maximum, and strives to make it easy for readers with a junior high school education level or above to understand and apply.

This book can be used by bus repairers to learn bus air conditioning maintenance, and can also be used as a teaching reference book for college and technical secondary school auto repair students.
