無動力風機現貨廠家材質齊全

　　無動力風機：風(feng)(feng)(feng)(feng)機(ji)就是我(wo)們說(shuo)的(de)風(feng)(feng)(feng)(feng)扇，通俗講無(wu)(wu)動力(li)(li)(li)風(feng)(feng)(feng)(feng)機(ji)就是不需要電(dian)源的(de)排風(feng)(feng)(feng)(feng)扇。無(wu)(wu)動力(li)(li)(li)風(feng)(feng)(feng)(feng)機(ji)是安(an)裝在房頂上的(de)。 無(wu)(wu)動力(li)(li)(li)風(feng)(feng)(feng)(feng)機(ji)是利用(yong)自(zi)然界的(de)自(zi)然風(feng)(feng)(feng)(feng)速推動風(feng)(feng)(feng)(feng)機(ji)的(de)渦輪旋轉，及利用(yong)室(shi)內外空(kong)氣(qi)對流(liu)(liu)的(de)原(yuan)理，將任(ren)何平行方向(xiang)的(de)空(kong)氣(qi)流(liu)(liu)動，加速并(bing)轉變為由下而上垂直的(de)空(kong)氣(qi)流(liu)(liu)動，以提高室(shi)內通風(feng)(feng)(feng)(feng)換(huan)氣(qi)效果的(de)一種裝置(zhi)。該風(feng)(feng)(feng)(feng)機(ji)不用(yong)電(dian)，無(wu)(wu)噪音，可長期運(yun)轉。

　　1、無(wu)(wu)動(dong)力(li)風(feng)(feng)機(ji)通常(chang)稱為無(wu)(wu)動(dong)力(li)風(feng)(feng)帽，是(shi)(shi)一(yi)種風(feng)(feng)力(li)推(tui)動(dong)旋轉(zhuan)的風(feng)(feng)動(dong)機(ji)，其(qi)(qi)實是(shi)(shi)有動(dong)力(li)的，稱其(qi)(qi)“無(wu)(wu)動(dong)力(li)”主要是(shi)(shi)表述(shu)其(qi)(qi)是(shi)(shi)一(yi)種不耗電能的機(ji)械，而將其(qi)(qi)稱作風(feng)(feng)機(ji)則是(shi)(shi)利(li)用其(qi)(qi)類似動(dong)力(li)風(feng)(feng)機(ji)旋轉(zhuan)的假象故作的誤導、欺騙消費方式(shi)。

　　2、風(feng)(feng)(feng)(feng)(feng)(feng)動(dong)機其(qi)實就是風(feng)(feng)(feng)(feng)(feng)(feng)車(che)，只不(bu)過無動(dong)力(li)(li)風(feng)(feng)(feng)(feng)(feng)(feng)機是一(yi)種特殊型式的立軸(zhou)式風(feng)(feng)(feng)(feng)(feng)(feng)車(che)，這個立軸(zhou)式風(feng)(feng)(feng)(feng)(feng)(feng)車(che)可通過外部風(feng)(feng)(feng)(feng)(feng)(feng)力(li)(li)吹(chui)動(dong)旋轉(zhuan)(zhuan)，也可以通過室(shi)內排風(feng)(feng)(feng)(feng)(feng)(feng)推動(dong)旋轉(zhuan)(zhuan)。當室(shi)外風(feng)(feng)(feng)(feng)(feng)(feng)力(li)(li)吹(chui)動(dong)風(feng)(feng)(feng)(feng)(feng)(feng)帽(mao)旋轉(zhuan)(zhuan)時(shi)未必表示其(qi)形(xing)成排風(feng)(feng)(feng)(feng)(feng)(feng)作用(yong)，風(feng)(feng)(feng)(feng)(feng)(feng)力(li)(li)較小時(shi)風(feng)(feng)(feng)(feng)(feng)(feng)車(che)旋轉(zhuan)(zhuan)速度(du)低(di)不(bu)可能形(xing)成離心功(gong)能，風(feng)(feng)(feng)(feng)(feng)(feng)速大時(shi)風(feng)(feng)(feng)(feng)(feng)(feng)車(che)旋轉(zhuan)(zhuan)速度(du)高(gao)，卻在室(shi)內能夠(gou)感受到外部風(feng)(feng)(feng)(feng)(feng)(feng)力(li)(li)倒灌(guan)。

　　3、無動(dong)力風機、無動(dong)力風帽就是(shi)一(yi)種(zhong)屋面(mian)自然通(tong)風裝置，無風天熱壓和風壓促使室(shi)內空氣從風帽葉片(pian)間排(pai)出，驅動(dong)風帽的旋(xuan)轉才是(shi)通(tong)風現象。

　　4、將無(wu)(wu)動(dong)力風(feng)(feng)帽(mao)定(ding)義為無(wu)(wu)動(dong)力風(feng)(feng)機(ji)具有顯而(er)易(yi)見的欺騙性，就是利(li)用其(qi)旋轉類似(si)動(dong)力風(feng)(feng)機(ji)的假象，是不可能獲得(de)動(dong)力風(feng)(feng)機(ji)的通風(feng)(feng)效能的。特別是這種無(wu)(wu)動(dong)力風(feng)(feng)帽(mao)非常(chang)容(rong)易(yi)損壞，損壞后更換會耗費(fei)用戶更多的資金。

　　5、無(wu)動力(li)風(feng)(feng)(feng)機跟風(feng)(feng)(feng)車、風(feng)(feng)(feng)力(li)機是(shi)一(yi)樣的(de)(de)立軸式風(feng)(feng)(feng)車結構型式，只是(shi)一(yi)種風(feng)(feng)(feng)動力(li)裝置而已，是(shi)不可能(neng)形成動力(li)風(feng)(feng)(feng)機的(de)(de)負壓通風(feng)(feng)(feng)功能(neng)的(de)(de)，因此，無(wu)動力(li)風(feng)(feng)(feng)機是(shi)一(yi)種欺騙、誤導消費的(de)(de)偽(wei)通風(feng)(feng)(feng)技術。
