但(dan)是，由于消防排(pai)煙風(feng)機(ji)盤(pan)(pan)管(guan)一(yi)般配備的(de)(de)均(jun)為粗效過(guo)濾器，排(pai)煙工(gong)程(cheng)貴，孔眼比較大(da)，凈板排(pai)煙工(gong)程(cheng)，在剛開始使用時(shi)，不免有粉塵(chen)(chen)穿(chuan)過(guo)過(guo)濾器而附著在盤(pan)(pan)管(guan)的(de)(de)管(guan)道(dao)和(he)濾片的(de)(de)外(wai)表。假如不及(ji)時(shi)清潔，就會使盤(pan)(pan)管(guan)中冷熱(re)風(feng)與盤(pan)(pan)管(guan)外(wai)流(liu)過(guo)的(de)(de)空(kong)氣(qi)之(zhi)間的(de)(de)熱(re)交換量(liang)減少，亳州排(pai)煙工(gong)程(cheng)，使盤(pan)(pan)管(guan)的(de)(de)換熱(re)效 能不能充分(fen)(fen)發揮(hui)出來。假如附著的(de)(de)粉塵(chen)(chen)許多，排(pai)煙工(gong)程(cheng)安裝，乃至將濾片間的(de)(de)部分(fen)(fen)空(kong)氣(qi)通道(dao)都堵塞的(de)(de)話，則一(yi)起還會減少風(feng)機(ji)盤(pan)(pan)管(guan)的(de)(de)送風(feng)量(liang)，使其(qi)空(kong)調(diao)功能進一(yi)步下降。只有定期對其(qi)進行有效的(de)(de)整理才(cai)更有利(li)于更好使用它(ta)，使其(qi)功能得到(dao)充分(fen)(fen)發揮(hui)。

 同一(yi)個防煙(yan)(yan)(yan)分區(qu)(qu)(qu)應(ying)(ying)采用同一(yi)種排(pai)(pai)煙(yan)(yan)(yan)方式。防煙(yan)(yan)(yan)分區(qu)(qu)(qu)內任意一(yi)點與(yu)(yu)近(jin)的(de)自然排(pai)(pai)煙(yan)(yan)(yan)窗之間(jian)(jian)的(de)水(shui)平距離不(bu)應(ying)(ying)大于(yu)30m。排(pai)(pai)煙(yan)(yan)(yan)風機(ji)(ji)應(ying)(ying)滿足(zu)280℃時連續工作30min的(de)要求，排(pai)(pai)煙(yan)(yan)(yan)風機(ji)(ji)應(ying)(ying)與(yu)(yu)風機(ji)(ji)入口處的(de)排(pai)(pai)煙(yan)(yan)(yan)防火閥聯鎖，當該閥關閉時，排(pai)(pai)煙(yan)(yan)(yan)風機(ji)(ji)應(ying)(ying)能停止運(yun)轉。防煙(yan)(yan)(yan)分區(qu)(qu)(qu)范圍是指以屋(wu)頂(ding)(ding)擋煙(yan)(yan)(yan)隔板、擋煙(yan)(yan)(yan)垂壁或從頂(ding)(ding)棚向(xiang)下突出不(bu)小于(yu)500mm的(de)梁為(wei)界，從地(di)板到屋(wu)頂(ding)(ding)或吊(diao)頂(ding)(ding)之間(jian)(jian)的(de)規定空(kong)間(jian)(jian)。
