style="font-size:14px;">設(shè)計通風(fēng)管道的兩個重要參數(shù)：風(fēng)量、風(fēng)壓。</span> </p> <p> <span style="font-size:14px;">1）風(fēng)量設(shè)計：為了確定送風(fēng)管道截面積大小，在風(fēng)管設(shè)計盡量小的情況下保證主管風(fēng)速5m/s，支管風(fēng)速3m/s。</span> </p> <p> <span style="font-size:14px;">風(fēng)管計算公式：所選設(shè)備風(fēng)量÷3600÷風(fēng)速=風(fēng)管截面積</span> </p> <p> <span style="font-size:14px;">同時注意保證風(fēng)管：長邊÷短邊≤4一般不要＞4特殊情況特殊對待。</span> </p> <p> <span style="font-size:14px;">2）風(fēng)壓設(shè)計：也叫機外靜壓。為了計算在送風(fēng)過程中克服阻力所需的參數(shù)，云南大禮堂通風(fēng)設(shè)備安裝公司哪家好。簡單來說，就是能將風(fēng)送多大距離的動力，云南大禮堂通風(fēng)設(shè)備安裝公司哪家好，云南大禮堂通風(fēng)設(shè)備安裝公司哪家好。風(fēng)壓估算值在彎頭、三通、變徑等較少的情況下，每米損失按8pa左右計算。</span> 昆明通風(fēng)設(shè)備公司哪家比較好？云南大禮堂通風(fēng)設(shè)備安裝公司哪家好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南大禮堂通風(fēng)設(shè)備安裝公司哪家好,通風(fēng)設(shè)備"

style="font-size:14px;">通風(fēng)是用機械或自然的方法向室內(nèi)送入足夠的新鮮空氣，同時把室內(nèi)的污濁空氣排出，使室內(nèi)空氣滿足衛(wèi)生要求和生產(chǎn)過程需要。建筑中完成通風(fēng)工作的各項設(shè)施，統(tǒng)稱通風(fēng)設(shè)備。通風(fēng)設(shè)備又分為自然通風(fēng)和機械通風(fēng)。</span><span style="font-size:14px;">自然通風(fēng)的動力是室內(nèi)外空氣溫度差所產(chǎn)生的“熱壓”和室外的作用所產(chǎn)生的“風(fēng)壓”，工作原理是利用熱壓進行自然通風(fēng)。室內(nèi)空氣溫度高于室外空氣溫度時，室內(nèi)熱空氣因密度小而上升，從上部窗孔排出。室外溫度較低、密度較大的空氣則從下部窗孔流入室內(nèi)。室內(nèi)外空氣溫差愈大、上下窗孔高差愈大、窗孔面積愈大，則通風(fēng)量也愈大。</span>

style="font-size:14px;">實驗室通風(fēng)與舒適性空調(diào)系統(tǒng)的通風(fēng)設(shè)計要求不同，主要目的是提供安全、舒適的工作環(huán)境，減少人員暴露在危險空氣下的可能。通風(fēng)主要解決的是工作環(huán)境對實驗人員的身體健康和勞動保護問題。實驗室通風(fēng)要求新風(fēng)全部來自室外，然后****排出室外，通風(fēng)柜的排氣不在室內(nèi)循環(huán)?；瘜W(xué)實驗室換氣要求每小時大于10次，物理實驗室每小時大于10次，實驗室無人時換氣可減少為6次，實驗室通風(fēng)柜設(shè)計數(shù)量要足夠，并且不作為***的室內(nèi)排風(fēng)裝置，儀器室或產(chǎn)生危險物質(zhì)的儀器上方設(shè)局部排風(fēng)系統(tǒng)。 </span></p><p> <span style="font-size:14px;"> 新建的實驗室設(shè)計有空調(diào)，因此通風(fēng)柜的使用臺數(shù)必須納入空調(diào)系統(tǒng)的計劃。由于通風(fēng)柜在生化實驗室中占有非常重要的位置，從改善實驗室環(huán)境、改善勞動衛(wèi)生條件，提高工作效率等方面考慮，通風(fēng)柜的使用臺數(shù)日益增多。隨之而來的是通風(fēng)管道，配管、配線、排風(fēng)等都成為實驗室建設(shè)的重要課題。</span> </p> <p> <span style="font-size:14px;"> 使用通風(fēng)柜的蕞大目的是排出實驗中產(chǎn)生的有害氣體，保護實驗人員的健康，也就是說要有高度的安全性和優(yōu)越的操作性，這就要求通風(fēng)柜應(yīng)具有如下功能，不倒流功能：應(yīng)具有在通風(fēng)柜內(nèi)部由排風(fēng)機產(chǎn)生的氣流將有害氣體從通風(fēng)柜內(nèi)部不反向流進室內(nèi)的功能。為確保這一功能的實現(xiàn)，一臺通風(fēng)柜與一臺通風(fēng)機用單一管道連接是蕞好的方法，不能用單一管道連接的，也只限于同層同一房間的可并聯(lián)，通風(fēng)機盡可能安裝在管道的末端（或屋頂處）。隔離功能：在通風(fēng)柜前面應(yīng)具用不滑動的玻璃視窗將通風(fēng)柜內(nèi)外進行分隔。補充功能：應(yīng)具有在排出有害氣體時，從通風(fēng)柜外吸入空氣的通道或替代裝置。</span>
