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(shí)驗(yàn)室內(nèi)在不使用通風(fēng)柜時也要時常通風(fēng)，這樣對試驗(yàn)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(shí)驗(yàn)也不精確。 4，寧波多功能通風(fēng)柜定做、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，寧波多功能通風(fēng)柜定做、室內(nèi)空氣溫度在-5℃至+40℃之間，24小時平均值不超過+25℃，寧波多功能通風(fēng)柜定做。工作人員在結(jié)束工作、離開通風(fēng)柜前，應(yīng)將通風(fēng)柜內(nèi)設(shè)備電源關(guān)閉。寧波多功能通風(fēng)柜定做</p><div style="width:100%;text-align:

style="text-indent:25px">排風(fēng)柜數(shù)量非常多，因此選擇合適的實(shí)驗(yàn)室設(shè)計方案尤為重要。作為進(jìn)行化學(xué)測試和實(shí)驗(yàn)的場所，實(shí)驗(yàn)室因其在保護(hù)實(shí)驗(yàn)人員健康安全以及保證實(shí)驗(yàn)順利進(jìn)行方面所起的重要作用而廣受關(guān)注，其中排風(fēng)柜又是實(shí)現(xiàn)這些功能的關(guān)鍵設(shè)備。設(shè)計實(shí)驗(yàn)室通風(fēng)空調(diào)系統(tǒng)的首要原則是建筑內(nèi)人員的安全，而在維持一個安全舒適的室內(nèi)環(huán)境的同時，如何減少能耗對于排風(fēng)柜密集程度較大的實(shí)驗(yàn)是一個很大的課題。?過去三十年內(nèi)，在排風(fēng)柜設(shè)備選型、系統(tǒng)設(shè)計及控制方面有過普遍的討論，技術(shù)也日趨成熟，主要體現(xiàn)在變風(fēng)量通風(fēng)空調(diào)系統(tǒng)(VAV)與排風(fēng)柜的有效結(jié)合以及相應(yīng)控制技術(shù)的提高。?相對于其它領(lǐng)域，實(shí)驗(yàn)室運(yùn)用VAV技術(shù)起步相對較晚，究其原因主要是因?yàn)樵趯ε棚L(fēng)柜采用變風(fēng)量系統(tǒng)的同時，對房間壓力和溫度進(jìn)行有效控制顯得相當(dāng)困難。</p><p style="text-indent:25px">怎樣做好通風(fēng)柜的檢查，需要堅持哪些原則：1.小問題要解決。有些時候，在應(yīng)用**的過程中，只是出現(xiàn)了一些小問題，看起來并沒有那么嚴(yán)重，但是大家一定不要忽視小問題，有些小問題沒有得到解決，就會變成比較嚴(yán)重的問題。小的問題能夠及時的去解決，不會對我們帶來更大的影響，而且也不會影響使用壽命，這才是應(yīng)用過程中很重要的事情。2.專業(yè)人員來完成。檢查通風(fēng)柜的時候，盡量的讓專業(yè)人員來做，一些普通的人很難真正的去做好具體的檢查工作，只有當(dāng)我們真正的找到這些專業(yè)的人員，讓他們來把具體的這些檢查方面的事情做得很好，這樣才可以有效的減少很多其他的問題，所以大家一定要及時的去考慮這些方面，讓專業(yè)的人員來完成這些具體的工作。為了真正實(shí)現(xiàn)高性能，通風(fēng)柜必須符合SEFA定義。</p><div

style="text-indent:25px">一個理想的實(shí)驗(yàn)室氣流流向應(yīng)該是從送風(fēng)口送出的氣流通過與室內(nèi)空氣的混合帶走室內(nèi)熱濕負(fù)荷，之后通過排風(fēng)柜抽走，但是事實(shí)上在各種因素的作用下這很難實(shí)現(xiàn)。通常認(rèn)為，排風(fēng)柜性能是和柜面氣流的平均風(fēng)速(簡稱面風(fēng)速)有直接關(guān)系。VAV系統(tǒng)設(shè)計的出發(fā)點(diǎn)就是為了確保穩(wěn)定的面風(fēng)速。JG/T222-2007標(biāo)準(zhǔn)中規(guī)定0.5m／s為安全操作的理想面風(fēng)速。?實(shí)驗(yàn)室排風(fēng)主要來源于排風(fēng)柜的排風(fēng)。在VAV中，排風(fēng)柜排風(fēng)量通?？梢酝ㄟ^兩種方式確定，即監(jiān)測排風(fēng)柜門位置或者監(jiān)測面風(fēng)速的大小。因?yàn)楸O(jiān)測柜門位置可以達(dá)到較為精確的水平，因此前者原則上可以通過調(diào)整排風(fēng)量確保恒定面風(fēng)速，但是它沒有考慮到其它類似于人員站在柜前等同樣會影響面風(fēng)速的因素。在對不一樣型號規(guī)格及材料的通風(fēng)柜安裝過程中，安裝公司技術(shù)水平是不是更強(qiáng)，將立即危害到實(shí)際應(yīng)用效果。寧波多功能通風(fēng)柜定做</p><p style="text-indent:25px">由于實(shí)驗(yàn)鋼制通風(fēng)柜對實(shí)驗(yàn)室設(shè)計的重要性，所以在實(shí)驗(yàn)鋼制通風(fēng)柜選擇時必須小心謹(jǐn)慎。寧波多功能通風(fēng)柜定做</p><p style="text-indent:25px">從歷史上看，大多數(shù)通風(fēng)柜在100 fpm的面風(fēng)速下操作，拉門完全打開。對于如今大多數(shù)通風(fēng)柜而言，這將是全速的，并且在大多數(shù)實(shí)驗(yàn)室中將構(gòu)成不必要的能量消耗。雖然每個實(shí)驗(yàn)室的通風(fēng)柜面風(fēng)速都沒有精確的數(shù)字，但標(biāo)準(zhǔn)的狀態(tài)范圍通常為60到100 fpm。標(biāo)準(zhǔn)對于指定特定面風(fēng)速如此模糊的一個原因是因?yàn)榕f款式通風(fēng)柜的100fpm與一些新通風(fēng)柜中的100fpm差別很大。此外，根據(jù)空氣平衡情況和現(xiàn)實(shí)生活條件，這些通風(fēng)柜將因?qū)嶒?yàn)室而異。在規(guī)劃實(shí)驗(yàn)室時需要考慮所有這些因素，以確保通風(fēng)柜達(dá)到理想的節(jié)能，同時仍保持安全。寧波多功能通風(fēng)柜定做</p></p><br
