style="text-indent:25px">這就要求通風(fēng)柜應(yīng)具有如下功能：(1)釋放功能：應(yīng)具備將通風(fēng)柜內(nèi)部產(chǎn)生的有害氣體用吸收柜外氣體的方式，使其稀釋后排出室外的功能。(2)不倒流功能：應(yīng)具有有害氣體從通風(fēng)柜內(nèi)部反向流進(jìn)室內(nèi)的功能。為確保這一功能的實(shí)現(xiàn)，一臺(tái)通風(fēng)柜與一臺(tái)通風(fēng)機(jī)用單一管道連接是好的方法，不能用單一管道連接的，也只限于同層同一房間的可并連，通風(fēng)機(jī)盡可能安裝在管道的末端(或?qū)禹斕?。(3)隔離功能：在通風(fēng)柜前面應(yīng)用不滑動(dòng)的玻璃視窗將通風(fēng)柜內(nèi)外進(jìn)行分隔。(4)補(bǔ)充功能：應(yīng)具有在排出有害氣體時(shí)，從通風(fēng)柜外吸入空氣的通道或替代裝置。(5)控制風(fēng)速功能：為防止通風(fēng)柜內(nèi)有害氣體逸出，需要有一定的吸入速度。決定通風(fēng)柜進(jìn)風(fēng)的吸入速度的要素有：實(shí)驗(yàn)內(nèi)容產(chǎn)生的熱量及與換氣次數(shù)的關(guān)系。其中主要的是實(shí)驗(yàn)內(nèi)容和有害物的性質(zhì)。通常規(guī)定，一般***的污染物為～，0或有危險(xiǎn)的有害物為～，劇毒或有少量放射性為～氣狀物為粒狀物為1m/s。為了確保這樣的風(fēng)速排風(fēng)機(jī)應(yīng)有必要的靜壓即空氣通過(guò)通風(fēng)柜管道時(shí)的摩擦阻力。確定風(fēng)速時(shí)還必須注意噪音問(wèn)題即通過(guò)空氣在管道內(nèi)流動(dòng)時(shí)以7～10m為限超過(guò)10m將產(chǎn)生噪音。通常實(shí)驗(yàn)室的室內(nèi)背景噪聲級(jí)別，噪聲限制值為70dB。江蘇通風(fēng)柜生產(chǎn)廠家，哪家好！</p><div
