風管(guan)(guan)(guan)(guan)(guan)主要(yao)指中央空調系統的(de)(de)通風管(guan)(guan)(guan)(guan)(guan)道，它常(chang)常(chang)被忽視，但卻(que)是空調系統的(de)(de)重(zhong)(zhong)(zhong)要(yao)組成部分，目前常(chang)見的(de)(de)風管(guan)(guan)(guan)(guan)(guan)主要(yao)有四種：1）鍍鋅(xin)薄(bo)鋼(gang)板(ban)(ban)風管(guan)(guan)(guan)(guan)(guan)；2)無(wu)機(ji)玻(bo)璃(li)(li)鋼(gang)風管(guan)(guan)(guan)(guan)(guan)；3)復合玻(bo)纖板(ban)(ban)風管(guan)(guan)(guan)(guan)(guan)；4)纖維(wei)織物風管(guan)(guan)(guan)(guan)(guan)。鍍鋅(xin)薄(bo)鋼(gang)板(ban)(ban)風管(guan)(guan)(guan)(guan)(guan)：早使(shi)用的(de)(de)風管(guan)(guan)(guan)(guan)(guan)，采用鍍鋅(xin)薄(bo)鋼(gang)板(ban)(ban)制(zhi)(zhi)作(zuo)，適合含濕量(liang)(liang)小的(de)(de)一般性氣(qi)體的(de)(de)輸送，有易(yi)生銹，無(wu)保溫和(he)消聲功能，制(zhi)(zhi)作(zuo)安裝周期長(chang)的(de)(de)特點。無(wu)機(ji)玻(bo)璃(li)(li)鋼(gang)風管(guan)(guan)(guan)(guan)(guan)：較(jiao)新的(de)(de)風管(guan)(guan)(guan)(guan)(guan)類型，采用玻(bo)璃(li)(li)纖維(wei)增強無(wu)機(ji)材料制(zhi)(zhi)作(zuo)，遇火(huo)不(bu)燃、耐腐蝕、份量(liang)(liang)重(zhong)(zhong)(zhong)，硬度大但較(jiao)脆，受自重(zhong)(zhong)(zhong)影(ying)響易(yi)變形酥裂(lie)，無(wu)保溫和(he)消聲性能，制(zhi)(zhi)作(zuo)安裝周期長(chang)。

1) 送(song)(song)風，包括通氣，如(ru)送(song)(song)鮮風和排(pai)氣，這個范(fan)圍很廣，如(ru)工廠車(che)間(jian)(jian)，生產場地空(kong)氣，由于有(you)害(hai)氣體產生需要(yao)(yao)排(pai)出室(shi)外(wai)，又(you)需要(yao)(yao)把室(shi)外(wai)空(kong)氣輸(shu)(shu)送(song)(song)至(zhi)室(shi)內。這時就要(yao)(yao)使(shi)(shi)(shi)用(yong)(yong)流量大(da)而壓力(li)小的空(kong)氣輸(shu)(shu)送(song)(song)管(guan)道(dao)，螺(luo)旋(xuan)風管(guan)就適用(yong)(yong)，一般情況下使(shi)(shi)(shi)用(yong)(yong)鍍鋅鐵管(guan)，有(you)腐蝕性及(ji)特別潮濕場所(suo)使(shi)(shi)(shi)用(yong)(yong)不銹鋼管(guan)。2) 送(song)(song)冷(leng)風。常見的是中央空(kong)調的管(guan)道(dao)，這種(zhong)管(guan)道(dao)需要(yao)(yao)加保(bao)溫(wen)(wen)材(cai)料(liao)。螺(luo)旋(xuan)風管(guan)可(ke)內貼(tie)保(bao)溫(wen)(wen)材(cai)料(liao)，外(wai)表看來(lai)美觀。3) 排(pai)油煙(yan)(yan)。飯店(dian)、酒樓(lou)、賓館的廚(chu)房(fang)均(jun)有(you)大(da)量油煙(yan)(yan)產生，需要(yao)(yao)排(pai)出，使(shi)(shi)(shi)用(yong)(yong)圓形的風管(guan)就是油煙(yan)(yan)囪。在這里，螺(luo)旋(xuan)風管(guan)該叫做(zuo)油煙(yan)(yan)管(guan)。4) 除塵。有(you)些(xie)工廠生產車(che)間(jian)(jian)很多塵埃，需要(yao)(yao)專門的除塵裝(zhuang)置，其(qi)中量較(jiao)大(da)的管(guan)道(dao)，可(ke)使(shi)(shi)(shi)用(yong)(yong)螺(luo)旋(xuan)風管(guan)。5) 散(san)裝(zhuang)物料(liao)輸(shu)(shu)送(song)(song)。有(you)些(xie)工廠的生產過程中，需要(yao)(yao)輸(shu)(shu)送(song)(song)松散(san)的顆粒，特別是比重(zhong)不大(da)的如(ru)發(fa)泡(pao)塑料(liao)粒之類的使(shi)(shi)(shi)用(yong)(yong)螺(luo)旋(xuan)風管(guan)造價低、效果好(hao)。

風機廣泛地應用于各個工業部門，一般講，離心式風機適用于小流量、高壓力的場所，而軸流式風機則常用于大流量、低壓力的情況，防火閥廠家應根據不同的情況選有不同的風機分類。1鍋爐用風機,鍋爐用風機根據鍋爐的規格可選用離心式或軸流式。又按防火閥它的(de)(de)作用(yong)(yong)(yong)分為(wei)鍋(guo)(guo)爐風(feng)(feng)(feng)(feng)機—向鍋(guo)(guo)爐內輸(shu)送空氣；鍋(guo)(guo)爐引(yin)風(feng)(feng)(feng)(feng)機把鍋(guo)(guo)爐內的(de)(de)煙氣抽走。2通(tong)(tong)風(feng)(feng)(feng)(feng)換(huan)氣用(yong)(yong)(yong)風(feng)(feng)(feng)(feng)機,這類(lei)風(feng)(feng)(feng)(feng)機一般(ban)是供工(gong)廠及(ji)各種(zhong)建筑物通(tong)(tong)風(feng)(feng)(feng)(feng)換(huan)氣及(ji)采暖通(tong)(tong)風(feng)(feng)(feng)(feng)用(yong)(yong)(yong)，要求壓力不高(gao)，但(dan)噪聲要求要低，可采用(yong)(yong)(yong)離心(xin)式(shi)或軸流(liu)式(shi)風(feng)(feng)(feng)(feng)機。
