變頻離心風機-變頻鼓風機簡單的說，變頻風機是采用(yong)變頻控制(zhi)技術(shu)來控制(zhi)風機(ji)根據條件(jian)變速運(yun)行。

一、*，風機是應用量大、應用面廣的通用性機械，與風機配套用的電機耗用電量約占全國總發電量的20%。因此在鼓風機、引風機等風機類設備上，推廣節能技術，取代落后的檔風板或閥門載流調節方式，使風機始終處于科學、經濟運行狀態，提高企業綜合經濟效益和社會效益，具有十分重要的意義。 
傳統風機流量的設計均以zui大風量需求來設計，其調整方式采用檔板、風門、回流、起停電機等方式控制，無法形成閉環回路控制，也較不考慮省電的觀念。電氣控制采用直接或Y-△起動，無法具有軟起動的功能，機械沖擊大，傳動系統壽命短，震動及噪音較大，需要的電源容量大，功率因數較低等是其主要的問題點。 
從流體力學原理得知，風(feng)機風(feng)量與轉(zhuan)(zhuan)速(su)及電(dian)機功(gong)(gong)率(lv)(lv)(lv)相關。當風(feng)量減(jian)少風(feng)機轉(zhuan)(zhuan)速(su)下(xia)(xia)降(jiang)時(shi)，其電(dian)動機輸(shu)入(ru)功(gong)(gong)率(lv)(lv)(lv)迅速(su)降(jiang)低。例如風(feng)量下(xia)(xia)降(jiang)到(dao)80%時(shi)，轉(zhuan)(zhuan)速(su)也下(xia)(xia)降(jiang)到(dao)80%，其軸功(gong)(gong)率(lv)(lv)(lv)則(ze)下(xia)(xia)降(jiang)到(dao)額(e)定功(gong)(gong)率(lv)(lv)(lv)的(de)51%；若風(feng)量下(xia)(xia)降(jiang)到(dao)50%時(shi)，軸功(gong)(gong)率(lv)(lv)(lv)將下(xia)(xia)降(jiang)到(dao)額(e)定功(gong)(gong)率(lv)(lv)(lv)20%。采用變(bian)頻調速(su)，改變(bian)風(feng)機電(dian)動機的(de)輸(shu)入(ru)頻率(lv)(lv)(lv)從而改變(bian)電(dian)動機、風(feng)機轉(zhuan)(zhuan)速(su)，達到(dao)調節空氣流量的(de)目的(de)，既滿足(zu)生產工藝變(bian)化的(de)要求，又(you)節省電(dian)能，是一舉多得的(de)措施(shi)。 

二、節電原理任何利用交流感應電動機作為電力傳動方式的生產機械，電動機的功率是按zui大負荷期額定負荷選擇的。而工作時絕大部分不能滿載運行，電動機工作于滿電壓、滿速度而負載很小，也會有很多時間空載運行，由電機設計和運行特性可以知道，電動機只有運行在滿載時才是效率zui高、功率因數COS￠狀況,輕載時降低，空載時甚至降到0.3以下，造成許多不必要的電能損耗。
