工(gong)廠(chang)通風(feng)(feng)(feng)(feng)管道(dao)的(de)(de)(de)通風(feng)(feng)(feng)(feng)方式分為兩(liang)類：排氣(qi)和(he)吹氣(qi)。 其(qi)原(yuan)理(li)主要分為熱壓(ya)通風(feng)(feng)(feng)(feng)和(he)風(feng)(feng)(feng)(feng)壓(ya)通風(feng)(feng)(feng)(feng)。通風(feng)(feng)(feng)(feng)系(xi)統則是(shi)(shi)按(an)照中低壓(ya)系(xi)統選用的(de)(de)(de)；如果(guo)不是(shi)(shi)空調(diao)系(xi)統的(de)(de)(de)風(feng)(feng)(feng)(feng)管，一般(ban)通風(feng)(feng)(feng)(feng)管道(dao)不需要保溫，排煙風(feng)(feng)(feng)(feng)管如果(guo)是(shi)(shi)室內(nei)安(an)裝，一般(ban)要做隔(ge)熱處(chu)(chu)理(li)，他們流(liu)是(shi)(shi)不同的(de)(de)(de)。通風(feng)(feng)(feng)(feng)設備(bei)當運送一般(ban)的(de)(de)(de)管道(dao)，管道(dao)應該是(shi)(shi)黑色的(de)(de)(de)鋼銹(xiu)(xiu)，防(fang)銹(xiu)(xiu)油漆刷柄，可噴(pen)含(han)塵氣(qi)體的(de)(de)(de)抗磨損保護層(ceng)，當周圍空氣(qi)濕度高，外壁(bi)管做是(shi)(shi)為了防(fang)止(zhi)腐蝕，防(fang)銹(xiu)(xiu)處(chu)(chu)理(li)。

解決(jue)各種通(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)道相(xiang)碰及協調的(de)(de)原則(ze)，一般(ban)為(wei)：“小管(guan)(guan)(guan)(guan)(guan)(guan)讓大管(guan)(guan)(guan)(guan)(guan)(guan)，有壓讓無壓”。例如，自來水管(guan)(guan)(guan)(guan)(guan)(guan)與風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)相(xiang)撞(zhuang)，則(ze)應(ying)當自來水管(guan)(guan)(guan)(guan)(guan)(guan)拐(guai)彎。冷、熱水管(guan)(guan)(guan)(guan)(guan)(guan)與下水管(guan)(guan)(guan)(guan)(guan)(guan)相(xiang)碰，則(ze)應(ying)改變冷、熱水管(guan)(guan)(guan)(guan)(guan)(guan)道。在我國的(de)(de)多個場(chang)所(suo)，尤其是中央空調的(de)(de)大型場(chang)所(suo)，通(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)道的(de)(de)使用是為(wei)普(pu)及的(de)(de)，它們是進行空氣流通(tong)，幫助空調完成作業(ye)的(de)(de)主要零部件。選擇(ze)好的(de)(de)通(tong)風(feng)(feng)材料很重要，選擇(ze)好得通(tong)風(feng)(feng)材料首先在風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)制作過程(cheng)中，要注意風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)表(biao)面是鋁箔(bo)(bo)材質(zhi)，為(wei)了(le)確保(bao)表(biao)面層不易損壞(huai)，鍍鋅螺旋風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)，因(yin)此(ci)要對鋁箔(bo)(bo)材質(zhi)作出規定，并且為(wei)了(le)保(bao)證安全(quan)也(ye)規定了(le)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)表(biao)層的(de)(de)鋁箔(bo)(bo)厚度。

通風(feng)(feng)管(guan)道(dao)是(shi)工(gong)(gong)(gong)業與(yu)民(min)用建筑(zhu)的通風(feng)(feng)與(yu)空調工(gong)(gong)(gong)程用金屬或(huo)復合(he)管(guan)道(dao)，是(shi)為(wei)了使空氣流通，降低有害氣體濃(nong)度(du)的一種(zhong)(zhong)市政基礎設施。通風(feng)(feng)管(guan)道(dao)加工(gong)(gong)(gong)的過(guo)程中應(ying)該盡量避免呈(cheng)現縱向接縫(feng)，但是(shi)一定(ding)不能呈(cheng)現橫向接縫(feng)。而且通風(feng)(feng)管(guan)道(dao)的咬口(kou)縫(feng)和(he)四角(jiao)的縫(feng)隙處(chu)，需求(qiu)按(an)照設計(ji)潔凈等級(ji)懇求(qiu)，然后還(huan)要(yao)采用密(mi)封膠將其堵(du)嚴。通風(feng)(feng)管(guan)道(dao)的橫截面分為(wei)三個種(zhong)(zhong)類：1、圓管(guan):圓管(guan)-般(ban)為(wei)直接安裝(zhuang)(zhuang)的管(guan)， 標(biao)(biao)記(ji)(ji)時(shi)應(ying)清楚標(biao)(biao)明(ming)其直徑;2、矩形管(guan):施工(gong)(gong)(gong)時(shi)一般(ban)建有矩形通風(feng)(feng)管(guan)道(dao)， 標(biao)(biao)記(ji)(ji)時(shi)應(ying)注明(ming)長度(du)和(he)寬(kuan)(kuan)度(du);3、外(wai)(wai)觀為(wei)矩形，內(nei)部帶有圓形:這種(zhong)(zhong)管(guan)子是(shi)在安裝(zhuang)(zhuang)后由外(wai)(wai)部粉末制成，打標(biao)(biao)時(shi)只需要(yao)標(biao)(biao)準定(ding)義的長度(du)和(he)寬(kuan)(kuan)度(du)即可。
