合理选择调节方式降低通风机电耗的方法

Reducing Power Consumption of Fan by Reasonable Regulation

用理论和实例分析说明了长期使用闸门法调节通风机工况点会造成大量的电能浪费。通过改用更改皮带轮降低风机转速的方法后 ,每年可节约大量电费 。

It is proved that fan operating point regulated by gate for long term can result plenty power consumption dissipating. After reducing fan speed by belt pulley, a lot of power rates can be saved each year.The economic benefits are very significant.
