1、想要(yao)讓排(pai)(pai)水(shui)管(guan)(guan)能(neng)(neng)夠很好(hao)的(de)(de)(de)(de)排(pai)(pai)水(shui)，我們(men)就(jiu)需要(yao)注(zhu)意在(zai)安裝排(pai)(pai)水(shui)管(guan)(guan)的(de)(de)(de)(de)時(shi)(shi)候，讓排(pai)(pai)水(shui)管(guan)(guan)能(neng)(neng)夠有一(yi)(yi)個輕微(wei)的(de)(de)(de)(de)斜坡，這(zhe)樣就(jiu)不會(hui)出現(xian)排(pai)(pai)水(shui)管(guan)(guan)有可(ke)能(neng)(neng)過高而出現(xian)當中央空調停止工作(zuo)時(shi)(shi)，內機的(de)(de)(de)(de)水(shui)會(hui)出現(xian)倒(dao)流的(de)(de)(de)(de)情(qing)況(kuang)，這(zhe)樣就(jiu)會(hui)將吊(diao)頂(ding)泡(pao)壞(huai)。2、還(huan)需要(yao)注(zhu)意的(de)(de)(de)(de)是(shi)(shi)在(zai)安裝排(pai)(pai)水(shui)管(guan)(guan)的(de)(de)(de)(de)時(shi)(shi)候要(yao)對排(pai)(pai)水(shui)管(guan)(guan)的(de)(de)(de)(de)外部(bu)做(zuo)(zuo)一(yi)(yi)層保(bao)溫(wen)處理(li)，如果不做(zuo)(zuo)保(bao)溫(wen)，那么就(jiu)會(hui)在(zai)制冷時(shi)(shi)間長(chang)后(hou)，排(pai)(pai)水(shui)管(guan)(guan)的(de)(de)(de)(de)表面會(hui)出現(xian)滴水(shui)的(de)(de)(de)(de)情(qing)況(kuang)，這(zhe)樣對吊(diao)頂(ding)是(shi)(shi)有著一(yi)(yi)定(ding)的(de)(de)(de)(de)損壞(huai)的(de)(de)(de)(de)。所以要(yao)使用一(yi)(yi)些保(bao)溫(wen)材料(liao)，將排(pai)(pai)水(shui)管(guan)(guan)的(de)(de)(de)(de)保(bao)溫(wen)做(zuo)(zuo)好(hao)。

消聲(sheng)(sheng)(sheng)(sheng)器是利用聲(sheng)(sheng)(sheng)(sheng)的吸收(shou)(shou)、反射、干涉等(deng)原理，降低(di)通風與空(kong)調系(xi)統中氣流噪聲(sheng)(sheng)(sheng)(sheng)的裝置。根(gen)據消聲(sheng)(sheng)(sheng)(sheng)原理的不同可以分(fen)為阻(zu)性(xing)、抗性(xing)、共振型和復合型等(deng)。一、阻(zu)性(xing)消聲(sheng)(sheng)(sheng)(sheng)器,阻(zu)性(xing)消聲(sheng)(sheng)(sheng)(sheng)器利用吸聲(sheng)(sheng)(sheng)(sheng)材(cai)(cai)(cai)料(liao)的吸聲(sheng)(sheng)(sheng)(sheng)作用而(er)消聲(sheng)(sheng)(sheng)(sheng)的。其構造是把吸聲(sheng)(sheng)(sheng)(sheng)材(cai)(cai)(cai)料(liao)固定在氣流流動(dong)的管(guan)道內(nei)壁(bi)，或按(an)一定方式排列(lie)在管(guan)道或殼體內(nei)構成阻(zu)性(xing)消聲(sheng)(sheng)(sheng)(sheng)器，吸聲(sheng)(sheng)(sheng)(sheng)材(cai)(cai)(cai)料(liao)能(neng)夠(gou)把入射在其上(shang)的聲(sheng)(sheng)(sheng)(sheng)能(neng)部(bu)分(fen)地吸收(shou)(shou)掉。聲(sheng)(sheng)(sheng)(sheng)能(neng)之所以能(neng)被吸收(shou)(shou)，是由于吸聲(sheng)(sheng)(sheng)(sheng)材(cai)(cai)(cai)料(liao)的多(duo)孔性(xing)和松散性(xing)。當(dang)聲(sheng)(sheng)(sheng)(sheng)波進入孔隙，引起孔隙中的空(kong)氣和材(cai)(cai)(cai)料(liao)產生(sheng)微小的振動(dong)，由于摩擦和粘滯阻(zu)力。使相(xiang)當(dang)一部(bu)分(fen)聲(sheng)(sheng)(sheng)(sheng)能(neng)化為熱能(neng)而(er)被吸收(shou)(shou)掉。
