排煙風機雖然(ran)在各種場合(he)(he)都(dou)有所運用，但是(shi)不(bu)(bu)同(tong)(tong)的(de)(de)場合(he)(he)也要(yao)挑選不(bu)(bu)同(tong)(tong)的(de)(de)消防排煙風機，迫臨要(yao)考(kao)慮消防排煙風機的(de)(de)類型問題，還要(yao)考(kao)慮國家環保規則(ze)。

　　而消防排煙風機的放置也是一大問題(ti)，首要(yao)消防(fang)排煙(yan)(yan)風(feng)(feng)機(ji)不能間(jian)隔地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)的邊壁太近(jin)，避免(mian)(mian)影響通(tong)(tong)(tong)風(feng)(feng)效果(guo)。充分(fen)利用定(ding)(ding)點(dian)(dian)救援站處的斜井(jing)和(he)地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)兩頭的消防(fang)排煙(yan)(yan)風(feng)(feng)機(ji)作為(wei)送入(ru)新(xin)(xin)風(feng)(feng)和(he)排煙(yan)(yan)的通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)，通(tong)(tong)(tong)風(feng)(feng)有必要(yao)保(bao)持橫通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)口處于(yu)正壓狀況(kuang)，避免(mian)(mian)煙(yan)(yan)氣(qi)流(liu)向通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)內。通(tong)(tong)(tong)風(feng)(feng)系統從(cong)安全(quan)地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)向經過橫通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)向事端(duan)地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)方向送風(feng)(feng)，按(an)捺煙(yan)(yan)氣(qi)進(jin)入(ru)橫通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)及未發作事端(duan)的地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)，滿意疏散人員迎(ying)著(zhu)新(xin)(xin)風(feng)(feng)進(jin)入(ru)橫通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)和(he)安全(quan)地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)內，一起確保(bao)等(deng)候區域所需(xu)求的新(xin)(xin)鮮空(kong)氣(qi)。依(yi)照(zhao)事端(duan)發作的不同地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)內區域選(xuan)用不同的防(fang)災通(tong)(tong)(tong)風(feng)(feng)方法。 “定(ding)(ding)點(dian)(dian)”防(fang)災通(tong)(tong)(tong)風(feng)(feng)計劃當列車實(shi)施定(ding)(ding)點(dian)(dian)救援時，確保(bao)“定(ding)(ding)點(dian)(dian)”范圍內一切的聯絡(luo)橫通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)(dao)中設置能夠回轉的風(feng)(feng)機(ji)從(cong)安全(quan)地(di)(di)道(dao)(dao)(dao)(dao)(dao)(dao)內獲得新(xin)(xin)鮮風(feng)(feng)。
