【正文】 而且燃燒時(shí)間長(zhǎng)，產(chǎn)生大量有毒煙氣。三是，燃?xì)饧坝秒娫O(shè)備多，高層建筑內(nèi)通常按不同的功能區(qū)設(shè)置用電設(shè)備。 可見(jiàn)高層建筑防排煙在確保建筑安全方面是非常重要的。 同樣 ， 1993 年 12 月 13日福州市馬尾高福紡織公司倉(cāng)庫(kù)發(fā)生火災(zāi)，除住在倉(cāng)庫(kù)內(nèi)的 37 個(gè)生靈被火魔奪走，隔壁臨時(shí)宿舍內(nèi)的 59 名打工妹有 24 個(gè)被濃煙嗆得無(wú)處逃生。a mechanical smoke exhaust system III 目錄 1緒論

近年來(lái)，高層建筑火災(zāi)事故呈明顯上升趨勢(shì)，群死群傷事故時(shí)有發(fā)生，給國(guó)家和人民生命財(cái)產(chǎn)造成了極大的損失。t set mechanical ventilation system. So this underground garage use natural ventilation. The garage exhaust system normally used for ventilation when fire disaster it will be used. Keywords： smoke resisting and exhausting。地下室車庫(kù)機(jī)械排煙設(shè)計(jì)涉及到 五個(gè)方面：防煙分區(qū)的劃分、排煙量的計(jì)算、排煙口、排煙風(fēng)機(jī)及排煙風(fēng)道的設(shè)計(jì)。樓梯間加壓送風(fēng)防煙設(shè)計(jì)涉及到三個(gè)方面 ：加壓送風(fēng)量的計(jì)算、加壓送風(fēng)系統(tǒng)的設(shè)置及加壓送風(fēng)系統(tǒng)壓力控制的設(shè)置。 關(guān)鍵詞 ： 防排煙；高層住宅；地下車庫(kù) ；機(jī)械加壓送風(fēng) 系統(tǒng) ；機(jī)械排煙 系統(tǒng) II A highrise residential smoke resisting and exhausting scheme design Abstract： This article is about some highrise residential design of includes two aspects, the first is residential portion of the floor stairwell pressurization air smoke design,the second is basement garage part of the design of mechanical smoke exhaust.
