摘要
本文介绍了变风量空调系统的基本原理,采用PLC控制技术对变风量空调系统的室内温度进行了PID控制方法的研究,以某一车间为控制区域,运用该方法进行控制,测量了室内温度和送风阀门开度的实时曲线,结果表明,该方法可行有效,控制效果良好。
This paper introduces the principle of the variable air volume （VAV）air-conditioning system. The control method of the air temperature in variable air volume system is studied based on PLC technology and PID control method, this method is used on the air-conditioning of one of work room ,the variable trends of air temperature and valve opening of fan are measured, the result shows that this method is effective.
