style="text-indent:25px">風機消聲器分為：離心風機消聲器、羅茨風機消聲器、鼓風機消聲器、軸流風機消聲器。風機消聲器主要用于降低各種風機風口、風道和封閉式機房進風口的空氣動力性噪聲。根據(jù)風機進出口結(jié)構不同，分為圓形結(jié)構和矩形結(jié)構。圓形結(jié)構分用于風機接管口為圓形,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(可裝防雨風帽)，*供設置在室外管道末端和封閉式機房進風口選用。由于風盤出口風速一般大于進口，故風量一定時，進風口面積要比出風口的大。若進出風口裝反了，風量會降低，但出風溫度會升高。制熱效果差，可能風盤選型有問題，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，都會導致制熱效果差。微穿孔板式消聲器是用厚度小于1mm的純金屬薄板制作。</p><div
