送冷風和熱風常見的是螺旋風管安裝中央空調的管道，這種管道需要加保溫材料。也可內貼保溫材料，使風道具有螺旋形的漂正規螺旋風管亮外觀(guan)，可免吊頂，從(cong)而降低了工(gong)程造(zao)價(jia)。送(song)新風和排氣，將有害氣體(ti)排出室(shi)外，把室(shi)外新鮮空氣送(song)至室(shi)內。一般(ban)而言，通風系統的(de)流量(liang)都很大，因此(ci)要求使用(yong)阻(zu)力較小(xiao)的(de)空氣輸送(song)管道，以節省造(zao)價(jia)和運行費用(yong)——就適(shi)用(yong)。一般(ban)情(qing)況下(xia)使用(yong)鍍鋅鐵(tie)管，有腐蝕性及特別(bie)潮濕的(de)場所(suo)使用(yong)不銹鋼管。

不銹鋼正規螺旋風管風管的空氣流動性好，有效通流面積大，由于強度大，因此風管振動引起的低頻噪聲更小，空螺旋風管安裝氣流動性(xing)(xing)(xing)能好(hao)，系統(tong)壓降小，日常運(yun)行系統(tong)耗(hao)電量(liang)少。目前還可(ke)以采用扁橢圓形風管(guan)來降低風管(guan)的(de)占(zhan)用空間高度(du)，由于風管(guan)的(de)兩邊是(shi)圓形，所以氣流穩定，風管(guan)的(de)剛性(xing)(xing)(xing)好(hao)，外(wai)露安裝美(mei)觀性(xing)(xing)(xing)好(hao)，是(shi)比較理想的(de)風管(guan)系列。
