跟著科學(xué)技能的不斷開展，大家對<a href="http://www.winlive.cn">隧道風(fēng)機(jī)</a>運(yùn)用的需求也越來越高，就當(dāng)前國外<a href="http://www.winlive.cn">隧道風(fēng)機(jī)</a>技能開展趨勢而言，將向隧道風(fēng)機(jī)低噪音的方向開展。　隧道風(fēng)機(jī)的噪聲是工業(yè)生產(chǎn)中噪聲污染源*首要來歷之一。隧道風(fēng)機(jī)大型化和高速化更使得噪聲疑問非常杰出。對低頻噪聲，隧道風(fēng)機(jī)首要經(jīng)過改進(jìn)隧道風(fēng)機(jī)結(jié)構(gòu)設(shè)計，降低本體噪聲，若達(dá)不到需求，可采納加裝消聲器隔音房等措施。綜上所述，這些技能既是國外隧道風(fēng)機(jī)將來開展趨勢，也是國內(nèi)隧道風(fēng)機(jī)職業(yè)在技能方面的盡力方向。</div> <div> 隧道風(fēng)機(jī)風(fēng)量的定義為:風(fēng)速V與風(fēng)道截面積F的乘積.大型隧道風(fēng)機(jī)由于能夠用風(fēng)速計準(zhǔn)確測出風(fēng)速,所以風(fēng)量核算也很簡單,直接用公式Q=VF,便可算出風(fēng)量.隧道風(fēng)機(jī)數(shù)量的確定依據(jù)所選房間的換氣次數(shù)，核算廠房所需總風(fēng)量，進(jìn)而核算得隧道風(fēng)機(jī)數(shù)量。核算公式：N=V×n/Q 其間：N——隧道風(fēng)機(jī)數(shù)量（臺）； V——場地體積（m3）； n——換氣次數(shù)（次/時）； Q——所選隧道風(fēng)機(jī)類型的單臺風(fēng)量（m3/h）。隧道風(fēng)機(jī)類型的挑選大概依據(jù)廠房實際情況，盡量選擇與原窗口尺度相匹配的隧道風(fēng)機(jī)類型，隧道風(fēng)機(jī)與濕簾盡量堅持必定的距離（盡可能別離裝在廠房的山墻兩邊），完成杰出的通風(fēng)換氣作用。排風(fēng)側(cè)盡量不接近鄰近建筑物，以防影響鄰近住戶。如從室內(nèi)帶出的空氣中含有污染環(huán)境，能夠在風(fēng)口設(shè)備噴水設(shè)備，吸鄰近污染物會集收回，不污染環(huán)境，達(dá)到高效節(jié)能的目的。</div>
