摘要
针对传统中央空调能耗大的问题,结合变频技术提出基于PLC和触摸屏的中央空调节能控制系统,设计了由PLC、变频器、温度传感器等器件构成的温差闭环控制系统。系统能自动调节变频器的工作频率,实现了对循环水泵的无级自动调速,达到了节能目的。
This paper combines with frequency conversion technology based on PLC and touch screen central air-condi- tioning energy saving control system, design the closed-loop automatic control system constituted by the plc inverter and temperature sensors to save energy by automatically adjust the frequency of transducer, realize automatically stepless speed regulating of the cycle pump.
