style="text-indent:25px">風(fēng)機消聲器分為：離心風(fēng)機消聲器、羅茨風(fēng)機消聲器、鼓風(fēng)機消聲器、軸流風(fēng)機消聲器。風(fēng)機消聲器主要用于降低各種風(fēng)機風(fēng)口、風(fēng)道和封閉式機房進風(fēng)口的空氣動力性噪聲。根據(jù)風(fēng)機進出口結(jié)構(gòu)不同，分為圓形結(jié)構(gòu)和矩形結(jié)構(gòu)。圓形結(jié)構(gòu)分用于風(fēng)機接管口為圓形,又分為A、B型兩種， A型兩端均為法蘭盤，直接串接于管道中(即管道消聲器)， B型一端為法蘭，另一端為直接大氣排空(可裝防雨風(fēng)帽)，*供設(shè)置在室外管道末端和封閉式機房進風(fēng)口選用。由于風(fēng)盤出口風(fēng)速一般大于進口，故風(fēng)量一定時，進風(fēng)口面積要比出風(fēng)口的大。若進出風(fēng)口裝反了，風(fēng)量會降低，但出風(fēng)溫度會升高。制熱效果差，可能風(fēng)盤選型有問題，更可能水流量出現(xiàn)問題，如過濾器堵塞、管道積氣，流經(jīng)盤管的水量少于額定量，都會導(dǎo)致制熱效果差。 </p><p 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。有源式消聲器基是使其在一定范圍內(nèi)與原來的聲場相抵消。</p><div
