中央空調通風管道

中央空調通風管道規劃(hua)注意事項 

①中央空調通風(feng)管(guan)道(dao)(dao)資料通常選(xuan)用薄鋼(gang)板涂漆或(huo)(huo)鍍鋅薄鋼(gang)板，利(li)用建筑(zhu)空間或(huo)(huo)地(di)溝(gou)的(de)也(ye)可(ke)選(xuan)用鋼(gang)筋混凝土或(huo)(huo)磚砌風(feng)道(dao)(dao)；其外表(biao)應(ying)抹光，請(qing)求高的(de)還要(yao)刷(shua)漆。地(di)溝(gou)風(feng)道(dao)(dao)要(yao)作防水(shui)處(chu)理(li)。放在(zai)有腐蝕(shi)氣體的(de)房間的(de)通風(feng)管(guan)道(dao)(dao)可(ke)選(xuan)用塑(su)料或(huo)(huo)玻璃鋼(gang)。  

②中(zhong)央空調通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的(de)(de)形(xing)(xing)狀通(tong)(tong)常為(wei)圓(yuan)(yuan)形(xing)(xing)和(he)矩(ju)形(xing)(xing)。圓(yuan)(yuan)形(xing)(xing)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)強度(du)大耗鋼量小(xiao)，但占有(you)用(yong)(yong)空間大，其彎管(guan)(guan)(guan)(guan)(guan)與三通(tong)(tong)需較(jiao)長(chang)間隔。矩(ju)形(xing)(xing)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)由于有(you)占有(you)用(yong)(yong)空間較(jiao)小(xiao)、易于安置、明裝較(jiao)漂亮等(deng)特色，故空調通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)多選(xuan)用(yong)(yong)矩(ju)形(xing)(xing)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)。矩(ju)形(xing)(xing)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的(de)(de)寬高比(bi)宜(yi)在(zai)2.5以下。高速通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)宜(yi)選(xuan)用(yong)(yong)圓(yuan)(yuan)形(xing)(xing)螺(luo)旋(xuan)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)。橢圓(yuan)(yuan)形(xing)(xing)螺(luo)旋(xuan)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)具有(you)圓(yuan)(yuan)形(xing)(xing)和(he)矩(ju)形(xing)(xing)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的(de)(de)長(chang)處，是一種抱負的(de)(de)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)，但由于需求專門的(de)(de)設備加工，現在(zai)用(yong)(yong)的(de)(de)較(jiao)少。
