摘要(Abstract):

介绍了空调机组环路式性能试验台的基本原理 ,并利用该试验台对控制系统进行实验研究。研究结果表明 :无论是PID控制还是模糊控制 ,都优于此前采用的手动控制方法 ;但采用模糊控制要比PID控制有更好的综合控制效果。
The principle of air-conditioning's properties testing device based on enthalpy difference method is introduced, and then the control system is verified using this device. The result of the research indicated that no matter which kind of control method used the control effects are super to manual control, and fuzzy control had better control effect than the PID control.
