摘　　要：以一个中央空调的变频节能改造项目为基础,介绍了PLC和变频器在中央空调节能控制系统中的一种应用。并介绍了冷冻水系统、冷却水系统、冷却塔风机系统等子系统实现变频节能控制的基本设计思想和实现方法。通过采用模糊PID控制弥补了传统PID控制的不足,有效地降低了中央空调的能耗,既有良好的经济效益,也有明显的社会效益。Based on a central air-conditioning frequency conversion reformation project,this paper introduced an application of PLC and the transducer in central air eonditioning energy-saving system. The paper describes the basic design idea of control system and the method for implementation of control process in chilled water system,cooling water system and cooling tower fan system. By using fuzzy-PID control,the insufficiency in traditional PID design has been surmounted. This kind of technological improvement decreases the energy consumption efficiently, which produces better economic benefits and social benefits.
