Design of Air Conditioning System for a Certain Type of Car in Shanghai

Abstract: This design is designed mainly for car air conditioning。 Design a complete car air conditioning system for the car structure。 To design as an example of cars to choose from, the load calculation of air conditioning system, air system and air conditioning equipment type selection design calculation method, such as more detailed instructions。 According to the area of climate parameters and cars run time, the characteristics of the summer cooling load is calculated first, and then according to the calculation of the cooling load data for the selection of air conditioning unit, the design is mainly on compressor, evaporator, condenser, etc to carry on the design calculation and selection of equipment。 This car is fully functional in the design of air conditioning, refrigeration, dehumidification, heating, ventilation and purification functions in an organic whole, can not only provide air conditioning in the summer, you can also provide heating in winter, and also has the mist, defrosting, adjust humidity, ventilation, dust removal, and other functions。 In this design, the sound insulation design, insulation and anti-corrosion design are made。

Keywords: air conditioning system; automotive air conditioning; load
