變頻器節(jié)能主要表現(xiàn)在風(fēng)機(jī)、水泵的應(yīng)用上。風(fēng)機(jī)、泵類(lèi)負(fù)載采用變頻調(diào)速后，節(jié)電率為20%～60%，這是因?yàn)轱L(fēng)機(jī)、泵類(lèi)負(fù)載的實(shí)際消耗功率基本與轉(zhuǎn)速的三次方成比例。當(dāng)用戶(hù)需要的平均流量較小時(shí)，風(fēng)機(jī)、泵類(lèi)采用變頻調(diào)速使其轉(zhuǎn)速降低，節(jié)能效果非常明顯。而傳統(tǒng)的風(fēng)機(jī)、泵類(lèi)采用擋板和閥門(mén)進(jìn)行流量調(diào)節(jié)，電動(dòng)機(jī)轉(zhuǎn)速基本不變，耗電功率變化不大。據(jù)統(tǒng)計(jì)，風(fēng)機(jī)、泵類(lèi)電動(dòng)機(jī)用電量占全國(guó)用電量的31%，占工業(yè)用電量的50%。在此類(lèi)負(fù)載上使用變頻調(diào)速裝置具有非常重要的意義。目前，應(yīng)用較成功的有恒壓供水、各類(lèi)風(fēng)機(jī)、中央空調(diào)和液壓泵的變頻調(diào)速。
