直流無動力通風(feng)器的(de)結構還需要呼吸產生水蒸氣,燃(ran)燒,和烹飪(ren),異味。如果你允(yun)許水汽(qi)積(ji)累,可能會破(po)壞結構,絕緣,或完(wan)成(cheng)。當(dang)操作時,空調經常從空氣中除(chu)(chu)去(qu)多余的(de)水分。除(chu)(chu)濕機也適合(he)去(qu)除(chu)(chu)空氣中的(de)水分。

  當地(di)排氣(qi)(qi)通(tong)風設備地(di)址問(wen)題,避免室內空(kong)氣(qi)(qi)污染(ran)源的(de)比(bi)容(rong)量高捕獲空(kong)氣(qi)(qi)中(zhong)的(de)污染(ran)物(wu)擴散(san)到環境。這可能包括(kuo)濕度(du)控制,方便控制,蒸汽(qi)從工(gong)業(ye)過(guo)(guo)程,從木材和金(jin)屬加工(gong)機械(xie)和塵埃(ai)。疲憊(bei)的(de)空(kong)氣(qi)(qi)可以(yi)通(tong)過(guo)(guo)壓(ya)頭或通(tong)過(guo)(guo)使用風扇和特(te)定區域的(de)密封。燃燒(如。、壁(bi)爐、燃氣(qi)(qi)熱(re)水器、蠟燭、燈、等)的(de)消耗氧(yang)氣(qi)(qi),二氧(yang)化碳(tan)和其他有(you)害氣(qi)(qi)體和煙霧,需(xu)要(yao)通(tong)風管。煙囪促進滲透(即打開(kai)。自(zi)然通(tong)風設備)負壓(ya)的(de)變化引起的(de)浮力,熱(re)空(kong)氣(qi)(qi)從煙囪離開(kai)。溫(wen)暖的(de)空(kong)氣(qi)(qi)往往是沉(chen)重,寒(han)冷的(de)空(kong)氣(qi)(qi)。

無動力通風天窗主(zhu)要(yao)用(yong)(yong)(yong)(yong)于工(gong)(gong)業(ye)建筑與(yu)民(min)(min)用(yong)(yong)(yong)(yong)建筑，如電力、鋼(gang)鐵(tie)、冶金、化工(gong)(gong)、造船。機械等(deng)工(gong)(gong)業(ye)廠房與(yu)大(da)型超市、商場、車站(zhan)、碼頭、居民(min)(min)樓，別墅等(deng)公共(gong)與(yu)民(min)(min)用(yong)(yong)(yong)(yong)建筑，供建筑設計選用(yong)(yong)(yong)(yong)及施(shi)工(gong)(gong)裝(zhuang)置(zhi)參(can)閱運用(yong)(yong)(yong)(yong)，并(bing)且能夠用(yong)(yong)(yong)(yong)于適用(yong)(yong)(yong)(yong)于強腐(fu)蝕性的建筑。

  無(wu)動力(li)通(tong)(tong)風天窗的用(yong)處是不消耗電(dian)能(neng)就能(neng)主動排出房間余熱，對房間進行通(tong)(tong)風換氣，改(gai)進房內溫度及衛生條(tiao)件，在工程中應用(yong)通(tong)(tong)風天窗獲得必定(ding)的通(tong)(tong)風節能(neng)作用(yong)。
