摘要
基于西门子可编程控制器S7-200的中央空调系统模糊PI变频节能改造项目。该项目运用模糊理论对可编程控制器的PID模块的比例系数和积分时间进行模糊控制,通过西门子MM430变频器和触摸屏对中央空调的冷冻水泵和冷却水泵电机进行变频调速,从而达到节能和提高空调运行舒适度及延长使用寿命的目的。
This paper is a renovation project based on PLC about the central air conditioner frequency control and energy saving by using fuzzy-PI control technique.This project applies the fuzzy theory to control the factor of proportionality and integration time of S7-200 PLC PID module,which can change the speed of freezing water pump and cooling water pump by applying MM430 transducer and touch screen to save energy and to improve comfort and work life.
