Abstract

The design of performance testing system for train air conditioning was done according to the NATIONAL STANDARD TB/T 1804-2003. The cooling capacity was measured by means of air enthalpy difference method. The hardware part of the test system consists of data collection unit and test instrument, while the software is programmed with Visual Basic 6.0, accompanied with the Microsoft Access database. The PLC unit and the touch screen are employed for local control of the system to achieve precise adjustment to the temperature and humidity of environmental chamber, the speed and flow of air. In view of the system characteristics of complex nonlinearity and being difficult to control exactly, test system adopts a fuzzy PID control based on plc to control experimental parameters such as temperature and humidity.
