中央(yang)空調(diao)通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)介紹 ①斷定中央(yang)空調(diao)通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的形狀(zhuang)和(he)挑選通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的尺(chi)度。②核(he)(he)算中央(yang)空調(diao)通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的壓(ya)力丟(diu)失(shi)。通(tong)(tong)過對通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的沿程(cheng)（摩(mo)擦(ca)）壓(ya)力丟(diu)失(shi)和(he)部分壓(ya)力丟(diu)失(shi)的核(he)(he)算，最終(zhong)斷定通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的尺(chi)度并挑選風(feng)(feng)(feng)機。通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的壓(ya)力丟(diu)失(shi)ΔP（Pa）,中央(yang)空調(diao)通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的壓(ya)力丟(diu)失(shi)ΔP=ΔPm+ΔPj 式中ΔPm---通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的沿程(cheng)壓(ya)力丟(diu)失(shi)（Pa）,ΔPj---通(tong)(tong)風(feng)(feng)(feng)管(guan)道(dao)(dao)(dao)的部分壓(ya)力丟(diu)失(shi)（Pa）

中央空調通風管道

中央空(kong)調通(tong)風管道(dao)規劃(hua)注(zhu)意事(shi)項 

①中央空調(diao)通(tong)風(feng)管道(dao)(dao)資料通(tong)常選用(yong)薄(bo)鋼板(ban)涂漆(qi)或(huo)鍍(du)鋅(xin)薄(bo)鋼板(ban)，利用(yong)建筑空間或(huo)地溝的也可(ke)(ke)選用(yong)鋼筋(jin)混凝土或(huo)磚砌風(feng)道(dao)(dao)；其外表應抹(mo)光，請求高(gao)的還要(yao)刷漆(qi)。地溝風(feng)道(dao)(dao)要(yao)作防水處理。放(fang)在有腐蝕(shi)氣(qi)體的房間的通(tong)風(feng)管道(dao)(dao)可(ke)(ke)選用(yong)塑(su)料或(huo)玻(bo)璃鋼。  

②中央(yang)空(kong)調通(tong)(tong)風(feng)(feng)管道(dao)(dao)的(de)(de)形狀通(tong)(tong)常(chang)為圓(yuan)(yuan)形和(he)矩(ju)形。圓(yuan)(yuan)形通(tong)(tong)風(feng)(feng)管道(dao)(dao)強度大(da)耗鋼量小，但(dan)(dan)占(zhan)有用(yong)空(kong)間大(da)，其彎管與三通(tong)(tong)需較長(chang)間隔(ge)。矩(ju)形通(tong)(tong)風(feng)(feng)管道(dao)(dao)由于(yu)有占(zhan)有用(yong)空(kong)間較小、易于(yu)安置、明裝較漂亮(liang)等特(te)色，故空(kong)調通(tong)(tong)風(feng)(feng)管道(dao)(dao)多選用(yong)矩(ju)形通(tong)(tong)風(feng)(feng)管道(dao)(dao)。矩(ju)形通(tong)(tong)風(feng)(feng)管道(dao)(dao)的(de)(de)寬(kuan)高(gao)(gao)比宜在2.5以(yi)下。高(gao)(gao)速通(tong)(tong)風(feng)(feng)管道(dao)(dao)宜選用(yong)圓(yuan)(yuan)形螺旋通(tong)(tong)風(feng)(feng)管道(dao)(dao)。橢圓(yuan)(yuan)形螺旋通(tong)(tong)風(feng)(feng)管道(dao)(dao)具有圓(yuan)(yuan)形和(he)矩(ju)形通(tong)(tong)風(feng)(feng)管道(dao)(dao)的(de)(de)長(chang)處，是一種抱負的(de)(de)通(tong)(tong)風(feng)(feng)管道(dao)(dao)，但(dan)(dan)由于(yu)需求(qiu)專門的(de)(de)設(she)備加(jia)工，現在用(yong)的(de)(de)較少(shao)。
