通(tong)(tong)風天(tian)窗(chuang)泛指具有通(tong)(tong)風排氣的窗(chuang)戶，本(ben)文所(suo)介紹的通(tong)(tong)風天(tian)窗(chuang)是工業(ye)用途的廠房屋頂(ding)通(tong)(tong)風天(tian)窗(chuang)。通(tong)(tong)風天(tian)窗(chuang)也(ye)稱作(zuo)屋頂(ding)通(tong)(tong)風器、自然通(tong)(tong)風器、通(tong)(tong)風氣樓，是工業(ye)建(jian)筑(zhu)(zhu)上常用大型集通(tong)(tong)風、采光、排煙(yan)為(wei)一(yi)體的通(tong)(tong)風設(she)備，在(zai)幫(bang)助建(jian)筑(zhu)(zhu)改善室內空(kong)氣環境(jing)方面起(qi)著重要作(zuo)用。    

通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)按照通(tong)(tong)風(feng)方式分為自然(ran)(ran)(ran)開敞(chang)式和電動啟(qi)閉式兩種。一、自然(ran)(ran)(ran)開敞(chang)式結構通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)適(shi)用于(yu)沒有(you)保溫(wen)和溫(wen)度控(kong)制(zhi)要(yao)求的(de)(de)(de)車間廠房，室(shi)內(nei)(nei)外(wai)空(kong)氣(qi)始終(zhong)處(chu)于(yu)流(liu)(liu)動狀態(tai)，煙(yan)塵、灰(hui)塵、熱(re)(re)氣(qi)等隨時隨地的(de)(de)(de)排出室(shi)外(wai)，室(shi)內(nei)(nei)空(kong)氣(qi)進行(xing)轉(zhuan)換(huan)更(geng)新。這(zhe)種通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)在成(cheng)本價格(ge)方面具有(you)優勢。一般在室(shi)內(nei)(nei)有(you)大(da)型(xing)熱(re)(re)源(yuan)和煙(yan)塵較(jiao)大(da)的(de)(de)(de)廠房采用這(zhe)種天(tian)窗(chuang)(chuang)(chuang)。二、電動啟(qi)閉式通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)是(shi)在自然(ran)(ran)(ran)開敞(chang)式通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)的(de)(de)(de)基(ji)礎上增設了電動系統和啟(qi)閉筏(fa)板(ban)，在需(xu)要(yao)通(tong)(tong)風(feng)換(huan)氣(qi)和排煙(yan)除塵的(de)(de)(de)時候打開電動啟(qi)閉筏(fa)板(ban)，在不(bu)需(xu)要(yao)通(tong)(tong)風(feng)排煙(yan)時，電動筏(fa)板(ban)處(chu)于(yu)關閉狀態(tai)，阻止室(shi)內(nei)(nei)外(wai)空(kong)氣(qi)對流(liu)(liu)。有(you)保溫(wen)需(xu)求的(de)(de)(de)可定(ding)制(zhi)保溫(wen)型(xing)筏(fa)板(ban)。這(zhe)種類型(xing)的(de)(de)(de)通(tong)(tong)風(feng)天(tian)窗(chuang)(chuang)(chuang)適(shi)用于(yu)平時偶(ou)爾通(tong)(tong)風(feng)換(huan)氣(qi)和排煙(yan)要(yao)求。優點(dian)是(shi)根據車間需(xu)要(yao)控(kong)制(zhi)性好(hao)。通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)在屋面(mian)的(de)(de)(de)布(bu)局不外乎(hu)兩種，那(nei)就是(shi)屋脊(ji)（主(zhu)脊(ji)）式(shi)(shi)和順坡(po)式(shi)(shi)，即橫向天(tian)(tian)窗(chuang)和縱向天(tian)(tian)窗(chuang)。一(yi)棟建筑選用(yong)何種型(xing)號(hao)規格的(de)(de)(de)通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)，是(shi)根據建筑使(shi)用(yong)環境性質和建筑面(mian)積(ji)等因素(su)綜合來考量的(de)(de)(de)，并由設計單位(wei)根據通(tong)(tong)風(feng)量和消防要(yao)求(qiu)最終確定通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)的(de)(de)(de)規格型(xing)號(hao)。屋脊(ji)式(shi)(shi)通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)坐落在屋頂(ding)的(de)(de)(de)屋脊(ji)處(chu)，按照氣(qi)(qi)流的(de)(de)(de)運動原理，此位(wei)置(zhi)的(de)(de)(de)通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)效(xiao)果最佳，對于室內的(de)(de)(de)熱(re)氣(qi)(qi)、煙(yan)塵(chen)、灰塵(chen)等能(neng)及時(shi)有效(xiao)的(de)(de)(de)排出(chu)，適用(yong)于大型(xing)結構建筑。順坡(po)式(shi)(shi)通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)適用(yong)于廠房(fang)室內熱(re)氣(qi)(qi)、煙(yan)塵(chen)不大，且廠房(fang)建筑較小(xiao)或多(duo)連跨(kua)的(de)(de)(de)廠房(fang)結構。也可以根據實際需要(yao)，主(zhu)脊(ji)式(shi)(shi)和順坡(po)式(shi)(shi)通(tong)(tong)風(feng)天(tian)(tian)窗(chuang)交叉使(shi)用(yong)。
