style="text-indent:25px">氣幕式通風(fēng)柜雖然增加了送風(fēng)動(dòng)力消耗,但氣幕式通風(fēng)柜的排風(fēng)量有效減少,排風(fēng)動(dòng)力消耗也有效降低,因此綜合而言,氣幕式通風(fēng)柜的節(jié)能效益是很大的,有些問(wèn)題還有待進(jìn)一步研究。氣幕式通風(fēng)柜通過(guò)射流將通風(fēng)柜操作口完全封閉,射流在流動(dòng)的過(guò)程中要不斷地卷吸室內(nèi)的空氣,但這部分卷吸量很少,對(duì)采暖空調(diào)房間的壓力影響不太明顯。而補(bǔ)風(fēng)型排風(fēng)柜排風(fēng)量比較大,當(dāng)柜門開(kāi)啟時(shí),其30%的排風(fēng)量要由室內(nèi)空氣補(bǔ)充,這對(duì)采暖空調(diào)房間而言,可能會(huì)造成壓力較明顯的變化。因此,采用氣幕式通風(fēng)柜的室內(nèi)壓力比補(bǔ)風(fēng)型通風(fēng)柜的室內(nèi)壓力更易于平衡。另外通風(fēng)柜的節(jié)能效果還與有害物的溫度、通風(fēng)柜的結(jié)構(gòu)、系統(tǒng)設(shè)計(jì)安裝是否合理等因素密切相關(guān),只要廣大暖通專業(yè)技術(shù)工作者根據(jù)具體情況,勇于探索,一定會(huì)節(jié)省更多的能量。海曙多功能通風(fēng)柜通風(fēng)柜排氣設(shè)備應(yīng)該用狹縫式排氣裝置，以讓排放有毒氣體不會(huì)影響研究人員。</p><div

style="text-indent:25px">如果通風(fēng)柜放在空調(diào)、凈化或采暖房間內(nèi)時(shí)，為了減少室內(nèi)空氣的排風(fēng)量，可以在柜門上方設(shè)風(fēng)幕，風(fēng)幕送出的空氣可取自室外或鄰室，風(fēng)量約為排風(fēng)量的70%~75%。這種通風(fēng)柜稱為供氣式通風(fēng)柜。其既可防止室內(nèi)橫向氣流的干擾，又可節(jié)省室內(nèi)的排風(fēng)量，大幅度減少室內(nèi)熱量和冷量的耗損。通風(fēng)柜局部排風(fēng)的應(yīng)用：局部排風(fēng)是直接從污染物源處排除污染物的一種局部通風(fēng)方式。當(dāng)污染物集中于某處發(fā)生時(shí)，局部排風(fēng)是比較有效的治理污染物對(duì)環(huán)境危害的通風(fēng)方式。如果這種場(chǎng)合采用完全通風(fēng)方式，反而使污染物在室內(nèi)擴(kuò)散；當(dāng)污染物發(fā)生量大時(shí)，所需的稀釋通風(fēng)量則過(guò)大，甚至在實(shí)際上難于實(shí)現(xiàn)。污染物定點(diǎn)發(fā)生的情況在工業(yè)廠房中很多，如電鍍槽、散料皮帶傳送的落料點(diǎn)或運(yùn)轉(zhuǎn)點(diǎn)、焊接工作臺(tái)、化學(xué)分析臺(tái)、噴漆、砂輪機(jī)等。民用建筑中也有一些定點(diǎn)產(chǎn)生污染物的情況，如廚房中的爐灶、餐廳中的火鍋、學(xué)校中的化學(xué)試驗(yàn)臺(tái)等。由此可見(jiàn)，局部排風(fēng)的應(yīng)用很普遍。定期更換通風(fēng)柜室內(nèi)凈化材料變形和定期清潔管道。</p><div
