摘要
文章介绍了一种由PLC和变频器在中央空调节能系统中新的应用。介绍了冷冻水系统、冷却水系统、冷却塔风机系统实现变频节能的基本设计思想和控制实现方法,通过使用模糊PID控制克服了传统PID控制设计中的参数调整困难的问题,并通过对具体实例的分析讲述了采用模糊PID控制节能技术的意义。
A new application of PLC and the transducer in Central Air Condition Energy-saving system is introduced. The paper describes basic design ideal of control system and method for implementation of control process in freeze and heat water system, cooling water system and cooling tower fan system. By using fuzzy- PID control, the parameter adjustment difficulty in traditional PID design has surmounted. Through practical example, the significance of fuzzy-PID control technology for energy-saving is related.
