廠房日常(chang)(chang)的(de)通(tong)風(feng)排煙(yan)、自然采光都是通(tong)過通(tong)風(feng)采光設(she)備來完成的(de)。通(tong)風(feng)設(she)施一般分為(wei)(wei)動力(li)(li)通(tong)風(feng)和(he)無(wu)動力(li)(li)通(tong)風(feng)。無(wu)動力(li)(li)通(tong)風(feng)就是我(wo)們常(chang)(chang)說的(de)電(dian)動采光排煙(yan)天(tian)窗。通(tong)過通(tong)風(feng)排煙(yan)天(tian)窗能夠較好的(de)保(bao)證良好的(de)室內(nei)通(tong)風(feng)采光環(huan)境和(he)工作人員(yuan)的(de)身心健康。常(chang)(chang)見的(de)電(dian)動采光排煙(yan)天(tian)窗主要分為(wei)(wei)三大類：

　　1、三角形電動采光排(pai)煙(yan)天窗

　　三(san)角(jiao)形(xing)消防排煙天窗(chuang)(chuang)的(de)(de)外觀(guan)形(xing)狀是三(san)角(jiao)形(xing)，分(fen)為(wei)上開(kai)式(shi)和下開(kai)式(shi)兩種(zhong)，上開(kai)式(shi)三(san)角(jiao)形(xing)天窗(chuang)(chuang)通風(feng)性(xing)能(neng)好;下開(kai)式(shi)天窗(chuang)(chuang)的(de)(de)防雨性(xing)能(neng)佳。

　　2、一(yi)字型電動采(cai)光(guang)排(pai)煙天窗

　　一(yi)(yi)字(zi)(zi)型(xing)天(tian)窗(chuang)從外形(xing)上看是一(yi)(yi)個(ge)規整的(de)長方(fang)體，像一(yi)(yi)個(ge)大寫的(de)“一(yi)(yi)”字(zi)(zi)。一(yi)(yi)字(zi)(zi)型(xing)通(tong)(tong)風天(tian)窗(chuang)按照布置方(fang)式可(ke)以分為一(yi)(yi)字(zi)(zi)型(xing)(單體式)電動通(tong)(tong)風天(tian)窗(chuang)和一(yi)(yi)字(zi)(zi)型(xing)(連體式)電動通(tong)(tong)風天(tian)窗(chuang)。一(yi)(yi)字(zi)(zi)型(xing)通(tong)(tong)風天(tian)窗(chuang)主要是適(shi)用于以通(tong)(tong)風為主，采光為輔的(de)工(gong)業廠房，其(qi)完(wan)全(quan)開啟角度(du)是90°，其(qi)排煙通(tong)(tong)風量較大。

　　3、圓拱形(xing)電動排煙(yan)天(tian)窗

　　圓(yuan)拱形(xing)天(tian)窗(chuang)(chuang)的(de)拱形(xing)頂(ding)部具有很(hen)好(hao)的(de)采(cai)光(guang)效果(guo)，側(ce)開式圓(yuan)拱形(xing)天(tian)窗(chuang)(chuang)頂(ding)部為固定(ding)式采(cai)光(guang)窗(chuang)(chuang)頂(ding)，窗(chuang)(chuang)扇(shan)設置在(zai)天(tian)窗(chuang)(chuang)兩側(ce)，用(yong)于(yu)平時開啟通風排煙。
