在空(kong)(kong)調送(song)(song)風(feng)系(xi)統中(zhong)(zhong)(zhong)，空(kong)(kong)調送(song)(song)風(feng)機(ji)送(song)(song)出(chu)的風(feng)必須通(tong)過(guo)主干(gan)管分配到(dao)支管中(zhong)(zhong)(zhong)；在排(pai)(pai)煙(yan)(yan)(yan)系(xi)統中(zhong)(zhong)(zhong)，煙(yan)(yan)(yan)氣由支管到(dao)主干(gan)管后，進(jin)入(ru)排(pai)(pai)煙(yan)(yan)(yan)風(feng)機(ji)排(pai)(pai)出(chu)。當(dang)建筑物內發生火(huo)災時，在通(tong)風(feng)、空(kong)(kong)調系(xi)統中(zhong)(zhong)(zhong)，為了防(fang)止(zhi)火(huo)勢(shi)通(tong)過(guo)送(song)(song)風(feng)系(xi)統蔓延(yan)(yan)，當(dang)送(song)(song)風(feng)系(xi)統中(zhong)(zhong)(zhong)氣體溫度達到(dao)70℃時，防(fang)火(huo)閥(fa)機(ji)構上熔(rong)斷器動作，閥(fa)門(men)亦迅速關閥(fa)，切斷煙(yan)(yan)(yan)氣與火(huo)勢(shi)沿風(feng)管蔓延(yan)(yan)的通(tong)路。同樣，在排(pai)(pai)煙(yan)(yan)(yan)系(xi)統中(zhong)(zhong)(zhong)，發生火(huo)災時，排(pai)(pai)煙(yan)(yan)(yan)閥(fa)開啟(qi)，進(jin)行(xing)排(pai)(pai)煙(yan)(yan)(yan)，為了截斷高溫煙(yan)(yan)(yan)氣在排(pai)(pai)煙(yan)(yan)(yan)管路中(zhong)(zhong)(zhong)流動，防(fang)止(zhi)火(huo)勢(shi)蔓延(yan)(yan)到(dao)另一防(fang)火(huo)分區，當(dang)排(pai)(pai)出(chu)的煙(yan)(yan)(yan)氣溫度達到(dao)280℃時，排(pai)(pai)煙(yan)(yan)(yan)防(fang)火(huo)閥(fa)、排(pai)(pai)煙(yan)(yan)(yan)口上熔(rong)斷器動作，閥(fa)門(men)必須自動關閉，阻(zu)止(zhi)排(pai)(pai)煙(yan)(yan)(yan)。由此可見(jian)，防(fang)火(huo)閥(fa)、排(pai)(pai)煙(yan)(yan)(yan)閥(fa)做到(dao)了該通(tong)則通(tong)，該斷則斷的隔煙(yan)(yan)(yan)阻(zu)火(huo)作用。

消聲器是利用聲的吸收、反射、干涉等原理，降低通風與空調系統中氣流噪聲的裝置。重慶通風管根據消聲原理的不同可以分為阻性、抗性、共振型和復合型等。一、阻性消聲器,阻性消聲器利用吸聲材料的吸聲作用而消聲的。其構造是把吸聲材料固定在氣流流動的管道內壁，值得信賴的通風管或按(an)一(yi)定方式排列(lie)在管道(dao)或殼體(ti)內構成阻性(xing)(xing)(xing)消(xiao)聲(sheng)(sheng)器，吸聲(sheng)(sheng)材料(liao)(liao)能(neng)夠把入射在其上的(de)聲(sheng)(sheng)能(neng)部分地(di)吸收(shou)(shou)掉。聲(sheng)(sheng)能(neng)之所以能(neng)被(bei)(bei)吸收(shou)(shou)，是由于(yu)吸聲(sheng)(sheng)材料(liao)(liao)的(de)多孔(kong)(kong)性(xing)(xing)(xing)和松散性(xing)(xing)(xing)。當聲(sheng)(sheng)波進入孔(kong)(kong)隙，引(yin)起孔(kong)(kong)隙中的(de)空氣和材料(liao)(liao)產(chan)生微小(xiao)的(de)振動，由于(yu)摩(mo)擦(ca)和粘滯阻力。使相當一(yi)部分聲(sheng)(sheng)能(neng)化為熱能(neng)而被(bei)(bei)吸收(shou)(shou)掉。
