確(que)保(bao)通(tong)(tong)風(feng)效果(guo)：高(gao)(gao)溫(wen)(wen)消(xiao)防排(pai)煙風(feng)機(ji)的(de)(de)使(shi)用(yong)(yong)介(jie)質本身(shen)(shen)溫(wen)(wen)度相對較高(gao)(gao)，且自身(shen)(shen)的(de)(de)運(yun)轉也是(shi)(shi)(shi)(shi)會產生(sheng)一定(ding)的(de)(de)溫(wen)(wen)度，若是(shi)(shi)(shi)(shi)將其(qi)放在(zai)密封(feng)環境(jing)(jing)中(zhong)，那么很容易就會導致高(gao)(gao)溫(wen)(wen)現(xian)(xian)(xian)象(xiang)發生(sheng)，針對于這種情況(kuang)在(zai)前期選擇安裝環境(jing)(jing)時就應(ying)(ying)該要(yao)多注意，好是(shi)(shi)(shi)(shi)能夠將其(qi)放在(zai)通(tong)(tong)風(feng)效果(guo)較好的(de)(de)環境(jing)(jing)中(zhong)，通(tong)(tong)過(guo)對流(liu)(liu)運(yun)動來有(you)(you)效降(jiang)低溫(wen)(wen)度，這是(shi)(shi)(shi)(shi)可(ke)以(yi)有(you)(you)效的(de)(de)防止高(gao)(gao)溫(wen)(wen)現(xian)(xian)(xian)象(xiang)的(de)(de)發生(sheng)。確(que)保(bao)電(dian)流(liu)(liu)大(da)小合適：消(xiao)防排(pai)煙風(feng)機(ji)的(de)(de)使(shi)用(yong)(yong)還是(shi)(shi)(shi)(shi)要(yao)注意電(dian)流(liu)(liu)問題，是(shi)(shi)(shi)(shi)應(ying)(ying)該要(yao)防止電(dian)流(liu)(liu)過(guo)大(da)現(xian)(xian)(xian)象(xiang)發生(sheng)，否(fou)則會讓(rang)在(zai)運(yun)行中(zhong)會因為電(dian)流(liu)(liu)過(guo)大(da)而產生(sheng)較多的(de)(de)電(dian)阻，而這也是(shi)(shi)(shi)(shi)會導致高(gao)(gao)溫(wen)(wen)現(xian)(xian)(xian)象(xiang)發生(sheng)。因為高(gao)(gao)溫(wen)(wen)會直接影響著(zhu)消(xiao)防排(pai)煙風(feng)機(ji)的(de)(de)使(shi)用(yong)(yong)，因此在(zai)日常使(shi)用(yong)(yong)中(zhong)就應(ying)(ying)該要(yao)采取措施(shi)來有(you)(you)效的(de)(de)防止高(gao)(gao)溫(wen)(wen)現(xian)(xian)(xian)象(xiang)發生(sheng)，且在(zai)高(gao)(gao)溫(wen)(wen)之后要(yao)采取措施(shi)來降(jiang)溫(wen)(wen)，以(yi)確(que)保(bao)安全。

1) 送風(feng)(feng)，包(bao)括通氣(qi)，如送鮮(xian)風(feng)(feng)和排(pai)氣(qi)，這(zhe)個(ge)范圍很廣，如工廠(chang)車間，生產(chan)場地空(kong)氣(qi)，由于有(you)害氣(qi)體產(chan)生需(xu)(xu)要(yao)排(pai)出(chu)(chu)室(shi)外，又需(xu)(xu)要(yao)把室(shi)外空(kong)氣(qi)輸(shu)送至(zhi)室(shi)內(nei)。這(zhe)時(shi)就要(yao)使用(yong)(yong)流量大(da)而壓力小的(de)(de)空(kong)氣(qi)輸(shu)送管(guan)(guan)(guan)道，螺(luo)旋(xuan)風(feng)(feng)管(guan)(guan)(guan)就適用(yong)(yong)，一般(ban)情況下(xia)使用(yong)(yong)鍍(du)鋅鐵管(guan)(guan)(guan)，有(you)腐蝕性及特別潮濕場所使用(yong)(yong)不銹鋼管(guan)(guan)(guan)。2) 送冷風(feng)(feng)。常見的(de)(de)是(shi)中央空(kong)調的(de)(de)管(guan)(guan)(guan)道，這(zhe)種(zhong)管(guan)(guan)(guan)道需(xu)(xu)要(yao)加保溫材料(liao)(liao)。螺(luo)旋(xuan)風(feng)(feng)管(guan)(guan)(guan)可內(nei)貼(tie)保溫材料(liao)(liao)，外表(biao)看(kan)來美觀。3) 排(pai)油煙。飯店、酒樓、賓館的(de)(de)廚(chu)房均有(you)大(da)量油煙產(chan)生，需(xu)(xu)要(yao)排(pai)出(chu)(chu)，使用(yong)(yong)圓形(xing)的(de)(de)風(feng)(feng)管(guan)(guan)(guan)就是(shi)油煙囪。在這(zhe)里，螺(luo)旋(xuan)風(feng)(feng)管(guan)(guan)(guan)該(gai)叫做油煙管(guan)(guan)(guan)。4) 除(chu)塵。有(you)些(xie)工廠(chang)生產(chan)車間很多塵埃，需(xu)(xu)要(yao)專門(men)的(de)(de)除(chu)塵裝(zhuang)置，其中量較大(da)的(de)(de)管(guan)(guan)(guan)道，可使用(yong)(yong)螺(luo)旋(xuan)風(feng)(feng)管(guan)(guan)(guan)。5) 散裝(zhuang)物料(liao)(liao)輸(shu)送。有(you)些(xie)工廠(chang)的(de)(de)生產(chan)過程中，需(xu)(xu)要(yao)輸(shu)送松散的(de)(de)顆(ke)粒，特別是(shi)比重不大(da)的(de)(de)如發泡塑料(liao)(liao)粒之類的(de)(de)使用(yong)(yong)螺(luo)旋(xuan)風(feng)(feng)管(guan)(guan)(guan)造價低、效(xiao)果好。

消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器是(shi)利用聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)吸(xi)(xi)收、反(fan)射、干涉等(deng)原理，降低通風(feng)與(yu)空調系統中氣(qi)流噪聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)裝(zhuang)置。根據消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)原理的(de)(de)不同可以分(fen)為(wei)阻(zu)性(xing)、抗性(xing)、共(gong)振型(xing)和(he)復合型(xing)等(deng)。一、阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器,阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器利用吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)的(de)(de)吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)作用而(er)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)。其構造是(shi)把吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)固定(ding)在氣(qi)流流動的(de)(de)管道內壁，或按一定(ding)方式排列在管道或殼體內構成阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)器，吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)能(neng)夠(gou)把入射在其上(shang)的(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)部分(fen)地吸(xi)(xi)收掉(diao)。聲(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)之(zhi)所以能(neng)被吸(xi)(xi)收，是(shi)由于吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)的(de)(de)多孔(kong)性(xing)和(he)松散性(xing)。當聲(sheng)(sheng)(sheng)(sheng)(sheng)波進入孔(kong)隙，引起孔(kong)隙中的(de)(de)空氣(qi)和(he)材(cai)料(liao)(liao)產生微(wei)小的(de)(de)振動，由于摩擦和(he)粘(zhan)滯阻(zu)力。使相當一部分(fen)聲(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)化為(wei)熱能(neng)而(er)被吸(xi)(xi)收掉(diao)。
