對于比較復雜(za)的(de)(de)民用建(jian)筑(zhu)，在設計階(jie)段，工(gong)(gong)廠通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)，各工(gong)(gong)種(暖通(tong)(tong)(tong)、給水(shui)(shui)排水(shui)(shui)，供電照(zhao)明與(yu)建(jian)筑(zhu))首先應(ying)協(xie)商好空(kong)間分(fen)隔，定(ding)(ding)出每種管(guan)(guan)(guan)道(dao)的(de)(de)標(biao)高范圍。一般(ban)(ban)情(qing)況下不得越出給自(zi)己(ji)規定(ding)(ding)的(de)(de)界限，遇有個別(bie)管(guan)(guan)(guan)段要越界時(shi)(shi)(shi)應(ying)與(yu)其(qi)(qi)他工(gong)(gong)程協(xie)商。通(tong)(tong)(tong)風(feng)(feng)(feng)系統則是(shi)(shi)按照(zhao)中低壓系統選用的(de)(de)；如果不是(shi)(shi)空(kong)調系統的(de)(de)風(feng)(feng)(feng)管(guan)(guan)(guan)，一般(ban)(ban)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)不需要保溫，排煙(yan)風(feng)(feng)(feng)管(guan)(guan)(guan)如果是(shi)(shi)室內(nei)安(an)裝(zhuang)，一般(ban)(ban)要做隔熱處理，他們流(liu)是(shi)(shi)不同的(de)(de)。通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)的(de)(de)橫截(jie)面(mian)分(fen)為三(san)個種類：1、圓(yuan)管(guan)(guan)(guan):圓(yuan)管(guan)(guan)(guan)-般(ban)(ban)為直(zhi)接安(an)裝(zhuang)的(de)(de)管(guan)(guan)(guan)， 標(biao)記時(shi)(shi)(shi)應(ying)清楚標(biao)明其(qi)(qi)直(zhi)徑;2、矩形管(guan)(guan)(guan):施工(gong)(gong)時(shi)(shi)(shi)一般(ban)(ban)建(jian)有矩形通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)， 標(biao)記時(shi)(shi)(shi)應(ying)注(zhu)明長度(du)和寬度(du);3、外(wai)觀為矩形，通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)企業(ye)，內(nei)部帶有圓(yuan)形:這種管(guan)(guan)(guan)子是(shi)(shi)在安(an)裝(zhuang)后由外(wai)部粉末制(zhi)成，打標(biao)時(shi)(shi)(shi)只需要標(biao)準定(ding)(ding)義(yi)的(de)(de)長度(du)和寬度(du)即可(ke)。

通風(feng)管(guan)(guan)(guan)道(dao)啟動(dong)前(qian)應將風(feng)機進口調(diao)節風(feng)門(men)嚴密關閉，以防誤操(cao)作(zuo)，帶負載(zai)啟動(dong)，電流(liu)表指示恢復到(dao)空載(zai)電流(liu)后，通風(feng)管(guan)(guan)(guan)道(dao)工(gong)程(cheng)，可(ke)調(diao)節風(feng)門(men)開度(du)在適(shi)當位置。通風(feng)管(guan)(guan)(guan)道(dao)加工(gong)的過程(cheng)中(zhong)應該盡量避免呈現(xian)縱向接(jie)縫(feng)，但是一(yi)定不能(neng)呈現(xian)橫向接(jie)縫(feng)。而且通風(feng)管(guan)(guan)(guan)道(dao)的咬口縫(feng)和四(si)角的縫(feng)隙處，需(xu)求(qiu)按照(zhao)設計潔凈等級懇求(qiu)，黃(huang)山通風(feng)管(guan)(guan)(guan)道(dao)，然后還(huan)要(yao)采(cai)用密封膠將其堵嚴。通風(feng)系統(tong)則是按照(zhao)中(zhong)低壓系統(tong)選用的；如果不是空調(diao)系統(tong)的風(feng)管(guan)(guan)(guan)，一(yi)般通風(feng)管(guan)(guan)(guan)道(dao)不需(xu)要(yao)保溫，排煙風(feng)管(guan)(guan)(guan)如果是室內(nei)安裝(zhuang)，一(yi)般要(yao)做(zuo)隔熱處理，他們流(liu)是不同的。
