Variable swash plate compressors recently have been used to improve fuel efficiency and SCM 435 or UNS C67300 were used as the material to manufacture them.As a result of structure analysis through static analysis that used ANSYS, SCM 435 currently being used was found structurally safe as it has that maximum stress is within the allowable range of their material property. Therefore, UNS C67300 was found to generate better fuel efficiency than the existing SCM 435 through structure analysis for automotive variable swash plate air conditioning compressor.

In this paper, a kind of efficient air-conditioning control system is proposed. PIC18F458 is adopted as main control unit of the system , which collects all kinds of analog singles such as temperature, humidity and so on, then convert them to digital by the A/D itself. After disposing and calculating each analog signal the system drives corresponding actuator to work to adjust temperature, humidity and cleanness of the air in bus, making passengers satisfied with air quality in bus.

Conditioning Control

In this paper, based on the Siemens S7-200 programmable controller in the central air conditioning control system, hardware and software of the central air-conditioning control system is designed. In hardware design PLC controller is used as controlling core to control temperature and humidity of the entire process. In the software design, control programming and multi-loop control of temperature, humidity PID algorithm are completed by using PLC programming software STEP7 because of its characteristics that it is easy to read and easy to achieve complete control. Lastly, Related parameter is set and the information is displayed by touching screen.
