SELECTION AND ARRANGEMENT OF AUTOMOTIVE

AIR-CONDITION

Abstract T he popularity and innovation of automotive air-conditioning is one of the important means to improve the competitiveness of the car. In recent years, with the development of the automotive industry and the improvement of people's living standards,people is increasing their requirements for vehicle comfort, reliability and safety , while the automotive air conditioning can greatly improve vehicle ride comfort. So, it is particularly important to research and develop automotive air-conditioning .

In this paper, the characteristics , principles, structure, and function of automotive air-conditioning are described.In addition, I will calculate and design compressor, condenser, evaporator and expansion valve for a certain brand of car.

Key words:compressor condenser evaporator expansion valve match arrangement
