The contents of the automotive air conditioning system of compressor, expansion valve, condenser, evaporator and automotive air conditioning other shop help equipment. Explains the working principle of automotive air conditioning system, compression, condensation and evaporation, expansion and so on four big process. For example automobile air-conditioning system each big system will generally failures and automotive air conditioning frost failure. Along with the development of the car industry and people on the car comfort, safety and reliability requirements increase, air conditioning system has become a modern car standard. Due to the height of the development of automobile electronic technology in cars and the application of, the result of the air conditioning system is more and more complicated, the degree of control part of the electronic more and more is also high, especially computer and technology of the network popularization and application, make automotive air conditioning comfort and technical performance have been significantly improved.
