基于PLC的楼宇中央空调节能控制方法研究

摘要

针对现代化智能楼宇多采用楼宇智能控制系统进行节能控制这一问题，本文采用西门子S7－226控制器控制技术和变频技术相结合的方法对楼宇节能中的中央空调系统进行自动控制设计，通过应用表明：本文所进行的基于PLC的楼宇中央空调节能控制方法可通过按需要调节水泵的输出流量达到现代楼宇的节能效果，楼宇节能提高了20%。%Intelligent control system is applied for modern intelligent buildings frequently,which can reduce the consumption of energy. Due to this problem, this paper adopts SIEMENS PLC controller (S7-226) and frequency conversion technology for automatic control design of the central air conditioning system in building energy saving. The application indicates that the energy saving effect of modern buildings is achieved by adjusting the output flow of the pump based on PLC technology, the building energy efficiency is increased by 20%.
