style="text-indent:25px">補風(fēng)型排風(fēng)柜：補風(fēng)型排風(fēng)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(fēng)沖刷呼吸區(qū)并帶走污染物；其次是節(jié)能性，因為補風(fēng)(較高可達(dá)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(fēng)型排風(fēng)柜在這兩個方面都無法達(dá)到人們預(yù)期效果。首先，補風(fēng)型排風(fēng)柜引入了大量補風(fēng)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(fēng)進(jìn)行稀釋，這本身減少了安全性，而且柜前補風(fēng)會嚴(yán)重影響柜面處的氣流，擾動加劇，很可能導(dǎo)致有害物溢出。而由于采用柜內(nèi)排風(fēng)，通過柜面的風(fēng)量減少導(dǎo)致風(fēng)速下降，后果更為嚴(yán)重，一般不建議采用。其次，開始的節(jié)能是考慮不對新風(fēng)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(fēng)溫度和房間溫度差值應(yīng)小于3℃，這一要求使其節(jié)能性不復(fù)存在。另外，一般的補風(fēng)型排風(fēng)柜都會在操作者頭部、肩部引起吹風(fēng)感，使人感到不適，而且補風(fēng)在冷表面上還會出現(xiàn)結(jié)冷凝水的情況。半密閉式通風(fēng)柜指由于操作上需要，經(jīng)常無法將污染物設(shè)備完全或部分地封閉，必須開有較大的工作孔的通風(fēng)柜。寧波余姚鋼制通風(fēng)柜生產(chǎn)廠家</p><p
