摘要
介绍用变频器PID闭环控制改造的措施及效益。用变频调速代替风机挡板解决了起动电流大 ,噪声高、风量控制不准不稳等问题 ,节能效益明显 ,改造投资费用仅半年收回。
The measure and benefit of inverter PID closed loop control reformation were introduced. The blower baffle plate was replaced by inverter speed regulator. The problems of strong starting current , loud noise, unaccurate and unstable of air flow control were solved. Energy saving benefit is obvious and the reformation investment cost can be regained in six months.
