style="text-indent:25px">氣幕式通風柜雖然增加了送風動力消耗,但氣幕式通風柜的排風量有效減少,排風動力消耗也有效降低,因此綜合而言,氣幕式通風柜的節(jié)能效益是很大的,有些問題還有待進一步研究。氣幕式通風柜通過射流將通風柜操作口完全封閉,射流在流動的過程中要不斷地卷吸室內(nèi)的空氣,但這部分卷吸量很少,對采暖空調(diào)房間的壓力影響不太明顯。而補風型排風柜排風量比較大,當柜門開啟時,其30%的排風量要由室內(nèi)空氣補充,這對采暖空調(diào)房間而言,可能會造成壓力較明顯的變化。因此,采用氣幕式通風柜的室內(nèi)壓力比補風型通風柜的室內(nèi)壓力更易于平衡。另外通風柜的節(jié)能效果還與有害物的溫度、通風柜的結構、系統(tǒng)設計安裝是否合理等因素密切相關,只要廣大暖通專業(yè)技術工作者根據(jù)具體情況,勇于探索,一定會節(jié)省更多的能量。</p><p style="text-indent:25px">補風型排風柜：補風型排風柜在過去一度受到青睞，主要基于兩方面的考慮：首先是安全性，因為它用送風沖刷呼吸區(qū)并帶走污染物；其次是節(jié)能性，因為補風(較高可達70％)不必處理即可送至柜前，從而省去了大量空調(diào)能耗。但實驗及研究表明，補風型排風柜在這兩個方面都無法達到人們預期效果。首先，補風型排風柜引入了大量補風基本上很少和室內(nèi)空氣混合而直接被吸走，這就使得房間內(nèi)其它空間區(qū)域可能存在的污染物只能通過少量的送風進行稀釋，這本身減少了安全性，而且柜前補風會嚴重影響柜面處的氣流，擾動加劇，很可能導致有害物溢出。而由于采用柜內(nèi)排風，通過柜面的風量減少導致風速下降，后果更為嚴重，一般不建議采用。其次，開始的節(jié)能是考慮不對新風處理這一前提而提出的。但指出為了確保溫度的一致性和操作者的舒適性，補風溫度和房間溫度差值應小于3℃，這一要求使其節(jié)能性不復存在。另外，一般的補風型排風柜都會在操作者頭部、肩部引起吹風感，使人感到不適，而且補風在冷表面上還會出現(xiàn)結冷凝水的情況。在實驗室柜體安裝的全過程中，必須綜合展開考慮。</p><div

style="text-indent:25px">實驗室空氣污染危害大，通風柜將環(huán)境有效凈化：目前我國市場上的通風柜種類多種多樣，功能也較為齊全。主要分為項抽式通風柜、狹縫式通風柜、旁通式通風柜、補風式通風柜、自然通風式通風柜等幾種類型。值得注意的是，這些通風柜可用于理化實驗室和生物實驗室，也可以用于潔凈實驗室，但不適用于生物安全三級和四級實驗室。通風柜在運作過程中需要注意有機廢氣的處理。有機廢氣治理是指用多種技術措施，通過不同途徑減少石油損耗、減少有機溶劑用量或排氣凈化以消除有機廢氣污染。由于有機廢氣污染源分布普遍，為防止污染，除減少石油損耗、減少有機溶劑用量以減少有機廢氣的產(chǎn)生和排放外，排氣凈化是目前切實可行的治理途徑。玻璃鋼通風柜的使用數(shù)量突飛猛進。寧波寧海鋼木結構通風柜價錢</p><p
