空調室外機的噪聲治理(li)怎么做(zuo)？

一(yi)、空調(diao)外(wai)機噪(zao)聲類型

空調外機噪音大的問題主要來自空調外機壓縮機和風扇排風，空調外機、空調機組等類型都有這兩種問題。壓縮機帶來的是振動低頻噪聲，穿透性強，是重點治理目標。

二(er)、空調(diao)外機(ji)噪聲治(zhi)理方法

1.因為空(kong)調(diao)外機(ji)的(de)主要噪(zao)聲(sheng)類型(xing)就是(shi)(shi)低(di)頻振動(dong)(dong)噪(zao)聲(sheng)，針對這種問題我們采用了(le)HKS效率(lv)更高(gao)的(de)彈性空(kong)調(diao)減震器(qi)，可以降(jiang)低(di)空(kong)調(diao)外機(ji)震動(dong)(dong)的(de)傳遞，避免(mian)震動(dong)(dong)通(tong)過(guo)地面、建筑結構傳播。這也是(shi)(shi)大(da)部分(fen)低(di)頻設備減震的(de)手段，使用相(xiang)應的(de)減震器(qi)或者減震基礎(chu)。減震器(qi)可以降(jiang)低(di)99的(de)震動(dong)(dong)傳遞率(lv)。

2.隔音措施主要是針對大型空調外機、空調室外機組，這類設備有排風噪聲、機械摩擦噪聲、電機噪聲等等，一些空調系統甚至還會有水泵噪聲。針對數量多、噪聲大的空調室外機系統

空壓機噪聲污染的控制噪聲是人們不需要的一種聲音，是一種公害已經提升到日程需要加以解決，噪聲的污染是多方面的，但是對于空壓機噪聲的污染分類有下，噪聲級在40dBA以上，對于睡眠就有不同程度的影響，長時間暴露在噪聲之下，要引起長久性耳朵問題，往往好會引起精神不佳、惡心嘔吐、甚至出現人身傷亡事故。

1、安裝空壓機消聲(sheng)器

主要(yao)噪聲(sheng)(sheng)(sheng)(sheng)源(yuan)是(shi)進(jin)、排(pai)氣口(kou)，應(ying)選用(yong)適宜的進(jin)排(pai)氣消聲(sheng)(sheng)(sheng)(sheng)器。空壓(ya)機進(jin)氣噪聲(sheng)(sheng)(sheng)(sheng)的頻譜呈低頻特性，進(jin)氣消聲(sheng)(sheng)(sheng)(sheng)器應(ying)選用(yong)抗(kang)性結構或以個、抗(kang)性為主的阻抗(kang)復合(he)式結構。空壓(ya)機的排(pai)氣氣壓(ya)大，氣流速度(du)高，應(ying)在空壓(ya)機排(pai)氣口(kou)使用(yong)小孔消聲(sheng)(sheng)(sheng)(sheng)器。

2、設(she)置空壓機(ji)消(xiao)聲(sheng)坑(keng)道

消聲坑(keng)(keng)道(dao)的(de)(de)(de)地(di)下或半地(di)下的(de)(de)(de)坑(keng)(keng)道(dao)，坑(keng)(keng)道(dao)壁用吸(xi)聲性好的(de)(de)(de)磚砌(qi)成。把空(kong)壓(ya)機的(de)(de)(de)進(jin)氣(qi)管(guan)和(he)消聲坑(keng)(keng)道(dao)連接(jie)，使空(kong)氣(qi)通過消聲坑(keng)(keng)道(dao)進(jin)入空(kong)壓(ya)機。采用消聲坑(keng)(keng)道(dao)可使空(kong)壓(ya)機的(de)(de)(de)進(jin)氣(qi)噪(zao)聲大(da)大(da)降低，使用壽命也比一般消聲器長。

3、建立隔聲罩

在空(kong)壓機(ji)的進(jin)、排氣(qi)口安裝(zhuang)消聲(sheng)(sheng)器或(huo)設置消聲(sheng)(sheng)坑道以(yi)后，氣(qi)流噪(zao)聲(sheng)(sheng)可以(yi)降到80db（a）以(yi)下(xia)，但空(kong)壓機(ji)的機(ji)械噪(zao)聲(sheng)(sheng)和電機(ji)噪(zao)聲(sheng)(sheng)仍(reng)然很高，因此還應在空(kong)壓機(ji)的機(ji)組上安裝(zhuang)隔聲(sheng)(sheng)罩。4、懸(xuan)掛空(kong)間吸聲(sheng)(sheng)體
