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，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，局部排風(fēng)是比較有效的治理污染物對環(huán)境危害的通風(fēng)方式。如果這種場合采用完全通風(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，所需的稀釋通風(fēng)量則過大，甚至在實際上難于實現(xiàn)。污染物定點發(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或運轉(zhuǎn)點、焊接工作臺、化學(xué)分析臺、噴漆、砂輪機(jī)等。民用建筑中也有一些定點產(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)試驗臺等。由此可見，局部排風(fēng)的應(yīng)用很普遍。</p><p style="text-indent:25px">正確使用通風(fēng)柜下要注意以下幾點： 1、通風(fēng)柜在使用時，每2小時進(jìn)行10分鐘的補(bǔ)風(fēng)（即開窗通風(fēng)）；使用時間超過5小時的，要敞開窗戶，注意避免室內(nèi)出現(xiàn)負(fù)壓。 2、實驗室內(nèi)在不使用通風(fēng)柜時也要時常通風(fēng)，這樣對試驗人員的身體健康有益； 3、當(dāng)2個以上的通風(fēng)柜共同使用1個風(fēng)機(jī)時，為避免操作失誤或不當(dāng)，風(fēng)機(jī)的“開”“關(guān)”只能由1個操作人員來控制；如另外一個通風(fēng)柜暫時不使用或要停止使用，可使用風(fēng)量調(diào)節(jié)閥來封閉通風(fēng)口；避免相互重復(fù)“開”“關(guān)”風(fēng)機(jī)，這樣不但對風(fēng)機(jī)的壽命產(chǎn)生損害，對實驗也不精確。 4、通風(fēng)柜在使用時，避免人員走動帶來的逆流風(fēng)向?qū)νL(fēng)柜的干擾； 5、室內(nèi)空氣溫度在-5℃至+40℃之間，24小時平均值不超過+25℃。通風(fēng)柜的安全性能是需要保障的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">通風(fēng)柜安裝時應(yīng)該注意哪些： 1、通風(fēng)柜盡可能安裝在管道的結(jié)尾，管道長度越短越好。通風(fēng)柜排風(fēng)通道盡可能直立，而且通道越高越好。 2、一臺通風(fēng)柜與一臺通風(fēng)機(jī)，用單一管道連接是較好的方法。 3、一臺通風(fēng)機(jī)連接的通風(fēng)柜越少越好。 4、實驗室通風(fēng)柜盡可能安裝在管道的末端，管道長度越短越好。 5、如果要改變風(fēng)道風(fēng)速，則應(yīng)配置相應(yīng)的變頻調(diào)整系統(tǒng)。 6、如果不能用單一管道連接的，只限于同層同一房間的可采用互相并連。 7、排風(fēng)通道的末端應(yīng)盡量避開補(bǔ)風(fēng)管道送氣口，防止排出的有害氣體通過排風(fēng)管道再被送至通風(fēng)柜。應(yīng)用于產(chǎn)熱量較大的工藝過程的通風(fēng)柜，稱為高溫通風(fēng)柜。寧波鄞州實驗室通風(fēng)柜報價</p><p
