中央空調(diào)通風(fēng)管道怎么清洗消毒除塵？詳細(xì)施工流程如下中央空調(diào)通風(fēng)管道內(nèi)，在長期使用中，會積聚大量的灰塵，不但會嚴(yán)重污染室內(nèi)的空氣，而且會增加風(fēng)管系統(tǒng)阻力，使中央空調(diào)系統(tǒng)的風(fēng)量下降。更重要的是，風(fēng)管內(nèi)空氣的溫度和濕度非常適宜有害細(xì)菌的生長和繁殖，直接成為一個隱秘的污染源。

按式(2.8－4)計算出斷面上各測點流速的平均值vp，則排風(fēng)罩的排風(fēng)量為： </p> <p> L=vp·F (m3/s) (2.8－6) </p> <p> 式中vp—平均風(fēng)速，m/s； </p> <p> F—管道斷面積，m2。 </p> <p> 靜壓法測量排風(fēng)罩的風(fēng)量 </p> <p> 在現(xiàn)場測定時，各管件之間的距離很短，不易找到比較穩(wěn)定的測定斷面，用動壓法測量流量有一定困難。在這種情況下，通過測量靜壓求得排風(fēng)罩的風(fēng)量。局部排風(fēng)罩壓力損失： </p> <p> 各種排風(fēng)罩的流量系數(shù)可用實驗方法求得，從公式(2.8－8)可以看出：μ值可以從有關(guān)資料查得。由于實際的排風(fēng)罩和資料上給出的不可能完全相同，按資料上的μ值計算排風(fēng)量會有一定的誤差。 </p> <p> 在一個有多個排風(fēng)點的排風(fēng)系統(tǒng)中，可先測出排風(fēng)罩的μ值，然后按公式(2.8－10)算出各排風(fēng)罩要求的靜壓，通過調(diào)整靜壓調(diào)整各排風(fēng)罩的排風(fēng)量，工作量可以減小。上述原理也適用于送風(fēng)系統(tǒng)風(fēng)量的調(diào)節(jié)。如均勻送風(fēng)管上要保持各孔口的送風(fēng)量相等，只需調(diào)整出口處的靜壓，使其保持相等。
