| Abstract: | In the paper,it states the principle of air supply with constant pressure by VFD(varying frequency device),the energy saving method and characteristics of velocity control by VFD.It is proved by actual operation that smoothly stepless variable velocity is realized from the motor fan directly controlled by VFD;power factor at network side is also increased;soft start is available with reduce of current impact;and significant results of energy saving is achieved as well. |
