(1)餐廳空(kong)調(diao)為全新(xin)風(feng)(feng)(feng)直(zhi)流式(shi)空(kong)調(diao)系(xi)統，空(kong)調(diao)新(xin)風(feng)(feng)(feng)首先送(song)(song)入(ru)(ru)餐廳，然后流入(ru)(ru)廚房(fang)經排(pai)風(feng)(feng)(feng)系(xi)統排(pai)出(chu)室(shi)外。此種方式(shi)投資較少，餐廳內采暖通風(feng)(feng)(feng)效果好。不(bu)(bu)足之(zhi)處是(shi)大(da)量空(kong)調(diao)風(feng)(feng)(feng)會被(bei)直(zhi)接(jie)排(pai)出(chu)，新(xin)風(feng)(feng)(feng)能(neng)耗大(da)，不(bu)(bu)利于節能(neng)。(2)將組合式(shi)空(kong)調(diao)機(ji)組的新(xin)風(feng)(feng)(feng)一部(bu)(bu)(bu)分(fen)直(zhi)接(jie)補(bu)入(ru)(ru)廚房(fang)，一部(bu)(bu)(bu)分(fen)送(song)(song)入(ru)(ru)餐廳，并通過回(hui)風(feng)(feng)(feng)機(ji)回(hui)到(dao)空(kong)調(diao)機(ji)。這樣可(ke)以部(bu)(bu)(bu)分(fen)解(jie)決新(xin)風(feng)(feng)(feng)能(neng)耗大(da)的問題，同(tong)時(shi)使(shi)用的靈活性也較大(da)。可(ke)在(zai)廚房(fang)設置測壓(ya)裝置，當廚房(fang)排(pai)風(feng)(feng)(feng)機(ji)全部(bu)(bu)(bu)工作(zuo)時(shi)，負壓(ya)增大(da)，鍍鋅(xin)板(ban)網吧新(xin)風(feng)(feng)(feng)管道制(zhi)作(zuo)，則回(hui)風(feng)(feng)(feng)電動(dong)閥(fa)關(guan)閉，回(hui)風(feng)(feng)(feng)機(ji)停，餐廳送(song)(song)風(feng)(feng)(feng)大(da)量補(bu)入(ru)(ru)廚房(fang);當少部(bu)(bu)(bu)分(fen)排(pai)風(feng)(feng)(feng)機(ji)開(kai)啟或排(pai)風(feng)(feng)(feng)機(ji)不(bu)(bu)工作(zuo)時(shi)，負壓(ya)不(bu)(bu)是(shi)很大(da)，則回(hui)風(feng)(feng)(feng)電動(dong)閥(fa)打開(kai)，回(hui)風(feng)(feng)(feng)機(ji)啟動(dong)，避免空(kong)調(diao)送(song)(song)風(feng)(feng)(feng)全部(bu)(bu)(bu)被(bei)排(pai)出(chu)。

如(ru)果(guo)(guo)已經把副煙(yan)(yan)(yan)(yan)(yan)道(dao)拆除，不(bu)銹鋼網吧(ba)新風管(guan)(guan)道(dao)制作，或是(shi)需要防止倒煙(yan)(yan)(yan)(yan)(yan)的(de)效果(guo)(guo)更好，那(nei)么使用煙(yan)(yan)(yan)(yan)(yan)道(dao)止逆閥(fa)(fa)。一般情況(kuang)下(xia)，油煙(yan)(yan)(yan)(yan)(yan)機(ji)(ji)的(de)止逆閥(fa)(fa)效果(guo)(guo)不(bu)是(shi)很明(ming)顯，而在煙(yan)(yan)(yan)(yan)(yan)道(dao)安裝(zhuang)止逆閥(fa)(fa)可以保護油煙(yan)(yan)(yan)(yan)(yan)機(ji)(ji)，使煙(yan)(yan)(yan)(yan)(yan)道(dao)里的(de)煙(yan)(yan)(yan)(yan)(yan)不(bu)會(hui)向管(guan)(guan)道(dao)和抽(chou)油煙(yan)(yan)(yan)(yan)(yan)機(ji)(ji)內(nei)倒灌。不(bu)過，安裝(zhuang)止逆閥(fa)(fa)后要定(ding)期(qi)清(qing)洗，否則會(hui)使止逆閥(fa)(fa)呈(cheng)打開狀態，網吧(ba)新風管(guan)(guan)道(dao)制作，失去效果(guo)(guo)，不(bu)銹鋼網吧(ba)新風管(guan)(guan)道(dao)制作，而且煙(yan)(yan)(yan)(yan)(yan)道(dao)止逆閥(fa)(fa)好兩(liang)年左右就(jiu)更換一次。隨著社會(hui)的(de)發展，很多家(jia)庭住宅的(de)廚房都以自家(jia)的(de)窗向外排放(fang)油煙(yan)(yan)(yan)(yan)(yan)，從而導致(zhi)樓(lou)(lou)下(xia)炒菜，樓(lou)(lou)上冒煙(yan)(yan)(yan)(yan)(yan)。所(suo)以家(jia)庭裝(zhuang)修(xiu)時，廚房煙(yan)(yan)(yan)(yan)(yan)道(dao)裝(zhuang)修(xiu)顯得非常重(zhong)要，一旦出現不(bu)合(he)理，就(jiu)會(hui)造成反味現象，對(dui)家(jia)居(ju)生活造成影響。

窗(chuang)(chuang)戶(hu)(hu)排(pai)煙(yan)(yan)(yan)注意安(an)(an)全(quan)有(you)些家庭為了避(bi)(bi)免串(chuan)煙(yan)(yan)(yan)問(wen)題，放棄原有(you)煙(yan)(yan)(yan)道直接在(zai)窗(chuang)(chuang)戶(hu)(hu)上開(kai)孔排(pai)煙(yan)(yan)(yan)。這樣做是可以的，但(dan)有(you)幾點需要注意：首先在(zai)窗(chuang)(chuang)戶(hu)(hu)或墻面開(kai)洞之前(qian)一定(ding)要經過物業的同意；其(qi)次注意安(an)(an)全(quan)問(wen)題。一般(ban)排(pai)煙(yan)(yan)(yan)管(guan)(guan)末端是金(jin)屬(shu)材質(zhi)的，如果開(kai)的洞太小，金(jin)屬(shu)傳熱可能會使(shi)玻璃炸(zha)裂傷及行人，且煙(yan)(yan)(yan)管(guan)(guan)通向窗(chuang)(chuang)外(wai)強(qiang)勁的北風對著吹會導致油煙(yan)(yan)(yan)倒灌。建議將(jiang)管(guan)(guan)道伸出去以后把管(guan)(guan)道往下窩，這樣還(huan)可以避(bi)(bi)免下雨(yu)時雨(yu)水流(liu)進管(guan)(guan)道，并把風擋(dang)在(zai)外(wai)面。
