排煙風機是(shi)一種(zhong)可以將廚房中(zhong)加工食物過程(cheng)中(zhong)發生的(de)異味(wei)、高(gao)溫、油煙氣體(ti)敏捷排走的(de)機(ji)械,該機(ji)器特(te)點是(shi)耐(nai)高(gao)溫功能良好、效率高(gao)。
送(song)風(feng)(feng)口、排煙(yan)口風(feng)(feng)量、余壓(ya)值(zhi)達不到標準要求的(de)(de)現象在工(gong)程中比較遍及,有的(de)(de)送(song)風(feng)(feng)口、排煙(yan)口的(de)(de)風(feng)(feng)速乃至(zhi)接近(jin)于零,造成這種現象的(de)(de)原因比較復雜,今(jin)日新耀空調工(gong)作人員小(xiao)大家具體(ti)講解一下(xia)?
主要變(bian)現在(zai)以下(xia)幾(ji)個方面: 合用(yong)正(zheng)壓(ya)(ya)送(song)(song)風(feng)(feng)(feng)系(xi)(xi)統(tong)未規(gui)(gui)劃(hua)(hua)壓(ya)(ya)差(cha)調理(li)設備:按(an)標(biao)準要求(qiu),機(ji)(ji)(ji)(ji)械加(jia)壓(ya)(ya)送(song)(song)風(feng)(feng)(feng)的(de)防(fang)煙(yan)(yan)(yan)樓梯間和合用(yong)前室(shi),宜(yi)別離獨立設置送(song)(song)風(feng)(feng)(feng)系(xi)(xi)統(tong),當必須共用(yong)一(yi)個系(xi)(xi)統(tong)時,應(ying)在(zai)通(tong)向合用(yong)前室(shi)的(de)支風(feng)(feng)(feng)管上(shang)設置壓(ya)(ya)差(cha)自動調理(li)設備。 現在(zai)很(hen)多規(gui)(gui)劃(hua)(hua)的(de)合用(yong)正(zheng)壓(ya)(ya)送(song)(song)風(feng)(feng)(feng)系(xi)(xi)統(tong)沒有規(gui)(gui)劃(hua)(hua)壓(ya)(ya)差(cha)調理(li)設備,無法構(gou)成(cheng)樓梯間的(de)余壓(ya)(ya)值(zhi)高于前室(shi)。 風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)選(xuan)(xuan)型(xing)(xing)不(bu)(bu)(bu)妥(tuo):按(an)標(biao)準要求(qiu),防(fang)煙(yan)(yan)(yan)樓梯間及前室(shi)、合用(yong)前室(shi)和消防(fang)電(dian)梯間前室(shi)的(de)機(ji)(ji)(ji)(ji)械加(jia)壓(ya)(ya)送(song)(song)風(feng)(feng)(feng)量,應(ying)由計(ji)算斷(duan)定(ding)(ding)(ding),當計(ji)算值(zhi)和標(biao)準規(gui)(gui)定(ding)(ding)(ding)的(de)值(zhi)不(bu)(bu)(bu)一(yi)致時,應(ying)按(an)兩者中較大值(zhi)斷(duan)定(ding)(ding)(ding)。 有的(de)規(gui)(gui)劃(hua)(hua)直接按(an)標(biao)準給定(ding)(ding)(ding)的(de)值(zhi)斷(duan)定(ding)(ding)(ding),往(wang)往(wang)導致選(xuan)(xuan)用(yong)的(de)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)風(feng)(feng)(feng)量、風(feng)(feng)(feng)壓(ya)(ya)偏(pian)小,不(bu)(bu)(bu)能滿足(zu)要求(qiu);有的(de)規(gui)(gui)劃(hua)(hua)采用(yong)通(tong)風(feng)(feng)(feng)與(yu)機(ji)(ji)(ji)(ji)械排(pai)煙(yan)(yan)(yan)合用(yong)系(xi)(xi)統(tong),但施(shi)工(gong)中未按(an)規(gui)(gui)劃(hua)(hua)要求(qiu)選(xuan)(xuan)用(yong)雙(shuang)速風(feng)(feng)(feng)機(ji)(ji)(ji)(ji);有的(de)建設單位(wei)不(bu)(bu)(bu)按(an)規(gui)(gui)劃(hua)(hua)的(de)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)類(lei)型(xing)(xing)訂購,購買(mai)功率規(gui)(gui)格較小的(de)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji),導致風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)風(feng)(feng)(feng)量嚴重(zhong)不(bu)(bu)(bu)足(zu)。
排煙風(feng)(feng)(feng)機(ji)運用(yong)無管道(dao)射流誘導(dao)通風(feng)(feng)(feng)系(xi)統時,可以整(zheng)個層面為通風(feng)(feng)(feng)風(feng)(feng)(feng)道(dao),送風(feng)(feng)(feng)風(feng)(feng)(feng)機(ji)、排風(feng)(feng)(feng)風(feng)(feng)(feng)機(ji)所(suo)需(xu)求風(feng)(feng)(feng)壓比運用(yong)管道(dao)時小(xiao)的(de)多(duo),這樣就(jiu)可以選用(yong)大(da)風(feng)(feng)(feng)量較低風(feng)(feng)(feng)壓的(de)風(feng)(feng)(feng)機(ji),使所(suo)需(xu)功率下(xia)降,大(da)幅度下(xia)降了作業本錢和(he)出資(zi)費(fei)用(yong),當送排風(feng)(feng)(feng)機(ji)間斷作業時,排煙風(feng)(feng)(feng)機(ji)仍可作業,起到部分通風(feng)(feng)(feng)換氣的(de)效果。
