空調室外機組(zu)噪(zao)聲(sheng)治理解(jie)決方(fang)案，空調機組(zu)隔音(yin)公司，空調機組(zu)隔音(yin)降噪(zao)治理：

你是(shi)否飽受著空(kong)(kong)(kong)調(diao)(diao)所帶(dai)來的(de)噪(zao)(zao)音?河南威盛環保相信很多人都有這樣(yang)的(de)煩惱，風(feng)(feng)機隔(ge)音降噪(zao)(zao)，在(zai)炎熱的(de)夏季(ji)開著空(kong)(kong)(kong)調(diao)(diao)，但(dan)是(shi)空(kong)(kong)(kong)調(diao)(diao)的(de)噪(zao)(zao)音過大嚴重影響(xiang)休息，但(dan)是(shi)關掉空(kong)(kong)(kong)調(diao)(diao)就熱的(de)睡不(bu)著，空(kong)(kong)(kong)調(diao)(diao)系統的(de)任(ren)務是(shi)保證建筑物內部冬(dong)暖夏涼(liang)，創造舒(shu)適的(de)室內環境;但(dan)在(zai)不(bu)少工程中由(you)于空(kong)(kong)(kong)調(diao)(diao)箱、送風(feng)(feng)機、回風(feng)(feng)機、排風(feng)(feng)機及整體式空(kong)(kong)(kong)調(diao)(diao)機等(deng)設備在(zai)安裝時未采取合適的(de)噪(zao)(zao)控(kong)措施，致使(shi)空(kong)(kong)(kong)調(diao)(diao)使(shi)用(yong)空(kong)(kong)(kong)間內及鄰近(jin)環境中的(de)噪(zao)(zao)聲值較高，影響(xiang)了人們的(de)工作(zuo)和休息。

一、噪聲源的分析

民(min)用(yong)建(jian)筑中(zhong)(zhong)(zhong)創(chuang)造(zao)舒(shu)適安(an)靜的(de)(de)(de)(de)環(huan)(huan)境是設(she)計的(de)(de)(de)(de)任務(wu)之一。空(kong)(kong)調(diao)系統(tong)的(de)(de)(de)(de)任務(wu)是保證建(jian)筑物內(nei)部(bu)冬(dong)暖夏(xia)涼，創(chuang)造(zao)舒(shu)適的(de)(de)(de)(de)室內(nei)環(huan)(huan)境;但在不少工(gong)程(cheng)中(zhong)(zhong)(zhong)由(you)于(yu)空(kong)(kong)調(diao)箱、送風機(ji)、回(hui)風機(ji)、排風機(ji)及(ji)整體式空(kong)(kong)調(diao)機(ji)等設(she)備在安(an)裝時未采取(qu)合適的(de)(de)(de)(de)噪(zao)(zao)控措施，致使空(kong)(kong)調(diao)使用(yong)空(kong)(kong)間(jian)內(nei)及(ji)鄰近(jin)環(huan)(huan)境中(zhong)(zhong)(zhong)的(de)(de)(de)(de)噪(zao)(zao)聲值(zhi)較(jiao)高，影響了人們的(de)(de)(de)(de)工(gong)作和休息(xi)。中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)調(diao)系統(tong)對室內(nei)聲環(huan)(huan)境產生(sheng)(sheng)影響的(de)(de)(de)(de)噪(zao)(zao)聲從頻譜特(te)性來看主要分布于(yu)中(zhong)(zhong)(zhong)低頻區域;首先是各種(zhong)風機(ji)運(yun)行時產生(sheng)(sheng)的(de)(de)(de)(de)空(kong)(kong)氣(qi)動力性噪(zao)(zao)聲經由(you)送風口(kou)、回(hui)風口(kou)甚至風管壁輻射(she)到室內(nei)空(kong)(kong)間(jian);再者運(yun)轉中(zhong)(zhong)(zhong)的(de)(de)(de)(de)設(she)備產生(sheng)(sheng)的(de)(de)(de)(de)振動通過安(an)裝支架、相(xiang)連管道等以固體導聲的(de)(de)(de)(de)形式經由(you)墻、梁、柱等建(jian)筑基礎(chu)輻射(she)出(chu)低頻噪(zao)(zao)聲。

二、 降噪措施

1、機房內噪聲(sheng)源的控制應(ying)以隔(ge)聲(sheng)、隔(ge)振為(wei)主(zhu)，吸聲(sheng)為(wei)輔(fu)。

2、隔(ge)聲(sheng)(sheng)是(shi)減少噪(zao)聲(sheng)(sheng)對其他室內干擾的辦法，隔(ge)聲(sheng)(sheng)好(hao)降噪(zao)效果就大。一個(ge)機房隔(ge)聲(sheng)(sheng)效果的好(hao)壞，取決于整個(ge)房間(jian)的隔(ge)墻、樓板及門窗等的綜合(he)處(chu)理。還要注意到房間(jian)孔洞與縫隙(xi)對圍護(hu)結(jie)(jie)構隔(ge)聲(sheng)(sheng)的影響很(hen)大，所以凡(fan)是(shi)管道穿過(guo)機房的圍護(hu)結(jie)(jie)構處(chu)，其孔洞四(si)周的縫隙(xi)必(bi)須用彈性材料填充密實;

3、為降(jiang)低室(shi)與(yu)室(shi)之(zhi)間通(tong)過(guo)(guo)風(feng)管(guan)傳(chuan)播的干擾(rao)噪(zao)(zao)聲，也為了(le)減(jian)少(shao)管(guan)道(dao)傳(chuan)到室(shi)內的噪(zao)(zao)聲，應安(an)裝風(feng)口消(xiao)聲器或消(xiao)聲百(bai)葉窗(chuang);必(bi)要時通(tong)風(feng)管(guan)道(dao)需要進行阻(zu)尼隔聲包扎(zha)，以減(jian)少(shao)通(tong)過(guo)(guo)管(guan)壁外泄的噪(zao)(zao)聲。

4、另外，在空(kong)調系(xi)統設計前(qian)期，應從噪控(kong)角(jiao)度選擇(ze)風道(dao)與(yu)設備。

冷卻塔是(shi)現代建(jian)筑(zhu)中典型的(de)噪聲振動(dong)污染源，已成為近年來環保(bao)投(tou)訴熱點(dian)之一，冷卻塔噪音處理(li)顯得尤為重(zhong)要。

常(chang)規(gui)冷(leng)(leng)卻(que)塔的(de)(de)主(zhu)要噪(zao)(zao)聲(sheng)是低(di)中(zhong)(zhong)頻為主(zhu)的(de)(de)循(xun)環風(feng)(feng)機(ji)(ji)(ji)通(tong)(tong)風(feng)(feng)噪(zao)(zao)聲(sheng)（有(you)的(de)(de)還(huan)會有(you)制冷(leng)(leng)壓縮機(ji)(ji)(ji)噪(zao)(zao)聲(sheng)），其(qi)中(zhong)(zhong)通(tong)(tong)風(feng)(feng)噪(zao)(zao)聲(sheng)又(you)包括(kuo)氣(qi)流(liu)所產生(sheng)的(de)(de)空(kong)氣(qi)動(dong)力(li)(li)性噪(zao)(zao)聲(sheng)和驅動(dong)機(ji)(ji)(ji)構產生(sheng)的(de)(de)機(ji)(ji)(ji)械噪(zao)(zao)聲(sheng)。因(yin)其(qi)噪(zao)(zao)聲(sheng)能量較高(gao)且(qie)低(di)頻噪(zao)(zao)聲(sheng)穿(chuan)透、繞射能力(li)(li)強、傳播范圍遠(yuan)，故而對(dui)周圍環境(jing)的(de)(de)影響為突出。由于冷(leng)(leng)卻(que)塔所用(yong)軸(zhou)流(liu)風(feng)(feng)機(ji)(ji)(ji)壓頭極低(di)，其(qi)風(feng)(feng)量和整體(ti)散熱(re)效果對(dui)消聲(sheng)系統的(de)(de)阻(zu)力(li)(li)損(sun)失極為敏感，故此類(lei)設備降噪(zao)(zao)治理的(de)(de)難點就(jiu)在于寬頻帶、高(gao)量值(zhi)的(de)(de)消聲(sheng)要求與冷(leng)(leng)卻(que)塔自身通(tong)(tong)風(feng)(feng)散熱(re)性能之間的(de)(de)尖銳矛盾(dun)；其(qi)噪(zao)(zao)聲(sheng)治理必須兼顧熱(re)工性能、結構工藝(yi)、日常(chang)維修、改造費用(yong)等一系列相關因(yin)素。通(tong)(tong)常(chang)，在這樣“處處摯肘”條件下的(de)(de)“后發(fa)制人(ren)”的(de)(de)改造難度和工程(cheng)費用(yong)都是相當大的(de)(de)！

對(dui)(dui)于冷(leng)卻塔，通常可能采取的噪聲(sheng)(sheng)治理措(cuo)施包括較為簡易的隔聲(sheng)(sheng)屏(ping)(ping)障(zhang)和較為更廣的整體通風消聲(sheng)(sheng)。當冷(leng)卻塔相對(dui)(dui)于敏感點(dian)處(chu)于較高(gao)位置、對(dui)(dui)側沒有高(gao)大反射建筑(zhu)物、所需降(jiang)噪量不是很(hen)高(gao)時，采用(yong)隔聲(sheng)(sheng)屏(ping)(ping)障(zhang)降(jiang)噪無疑(yi)是為經濟、適用(yong)的噪聲(sheng)(sheng)治理對(dui)(dui)策。
