介绍了某工厂循环冷却水变频节能控制系统,通过从节能角度深入研究被控对象,提出了带温差补偿的恒压控制策略,并给出实际节能率。
This paper introduces a frequency conversion energy saving control system of circulating cooling water in a factory. By studying the controlled object from energy saving perspective, a constant pressure control strategy with temperature difference compensation is proposed and the actual energy saving rate is given.
