style="text-indent:25px">消聲器的選用與設(shè)置：對中、高頻噪聲源，宜采用阻性或復(fù)合型消聲器；對于低、中頻噪聲源，宜采用共振型消聲器、膨脹型消聲器等抗性消聲器；對于脈動低頻噪聲源、變頻帶噪聲源，宜采用抗性或微穿孔板阻抗復(fù)合式消聲器。確定空調(diào)系統(tǒng)所需消聲量后，根據(jù)具體情況選擇消聲器形式，之后，根據(jù)已知的風(fēng)量、消聲器設(shè)計流速和消聲量，確定消聲器的種類、型號、數(shù)量。消聲器一般應(yīng)設(shè)于空調(diào)機房和空調(diào)房間之間考近空調(diào)機房，且氣流穩(wěn)定的直管段上。</p><p style="text-indent:25px">一般采用靜態(tài)消聲量來表示消聲器的消聲效果，因為靜態(tài)消聲量是一個定值，而動態(tài)消聲量受氣流速度的影響，是一個不定值，故評價指標以用靜態(tài)消聲量為宜。當(dāng)聲源經(jīng)靜態(tài)消聲后的剩余聲級（簡稱靜態(tài)出口聲級）大于消聲器氣流噪聲級時，消聲器的動態(tài)、靜態(tài)消聲量基本一致，不受氣流的影響；當(dāng)消聲器靜態(tài)出口聲級低于消聲器氣流噪聲級時，則消聲器的動態(tài)消聲量低于靜態(tài)消聲量，其差值隨流速的增加而增大；當(dāng)氣流噪聲級大于消聲器入口聲級時，此時消聲器不僅不能消聲，反而變成了一個噪聲放大器。為解決靜態(tài)和動態(tài)消聲量可能不一致的問題，有些消聲器產(chǎn)品已采用靜態(tài)消聲量和氣流噪聲級兩個指標同時表示產(chǎn)品的聲學(xué)性能。消聲器主要由消聲筒、消聲片、上下封板（或封頭）、支座、起吊環(huán)、銘牌等零部件組成。</p><div
