style="font-size:14px;color:#006600;">1無序送風(fēng)會(huì)造成廚房的工作環(huán)境惡劣。特別是在夏季，雖然餐廳內(nèi)通常會(huì)安裝一些局部柜式空調(diào)機(jī)以降低餐廳的室內(nèi)溫度，但室內(nèi)空氣補(bǔ)入廚房，并不能消除廚房的熱負(fù)荷并降低廚房溫度。由于廚房油煙較大，如果在廚房內(nèi)設(shè)局部柜式空調(diào)機(jī)以降低廚房內(nèi)的溫度，柜式空調(diào)機(jī)的回風(fēng)過濾則應(yīng)定期清理。 2.對(duì)于設(shè)置集中空調(diào)系統(tǒng)的建筑來說，廚房的工作環(huán)境能夠保證，其補(bǔ)風(fēng)多為有序送風(fēng)，靈活性也較大，在目前廚房的通風(fēng)系統(tǒng)中，多為以下三種補(bǔ)風(fēng)方式：（1）餐廳空調(diào)為全新風(fēng)直流式空調(diào)系統(tǒng)，空調(diào)新風(fēng)首先送入餐廳，然后流入廚房經(jīng)排風(fēng)系統(tǒng)排出室外。此種方式投資較少，餐廳內(nèi)采暖通風(fēng)效果好。不足之處是大量空調(diào)風(fēng)會(huì)被直接排出，新風(fēng)能耗大，不利于節(jié)能。</span>

廚房排煙風(fēng)量計(jì)算與工廠、實(shí)驗(yàn)室排除有害氣體一樣，要把所產(chǎn)生的有害氣體全部排除干凈，屬于專業(yè)排煙技術(shù)。排煙風(fēng)量計(jì)算應(yīng)該以捕捉全部的油煙熱氣為基準(zhǔn)，不是*等同于簡單的通風(fēng)換氣。根據(jù)流體力學(xué)原理，對(duì)排煙罩吸排氣體的流動(dòng)過程加以說明，這樣有助于計(jì)算方法的比較，也有助于對(duì)其他類型排煙設(shè)備進(jìn)行分析。 </p> <p> 排煙罩的排風(fēng)原理 </p> <p> 壓力的傳播和聲音的傳播是一樣的，在空氣中壓力也是以聲音的速度在傳播。氣體被吸入負(fù)壓區(qū)，形成氣流，以負(fù)壓區(qū)為中心形成一個(gè)球形的等壓面，也稱作等速面。在這個(gè)等壓面上壓力的大小相等，壓力引起氣流的流動(dòng)速度也相同，流線處處與球形等壓面垂直。在不同半徑的等壓面上，球形面積不同，流速不同，通過球形面積流量相等，也就是與吸風(fēng)口的流量相同。也就是以負(fù)壓區(qū)中心形成一個(gè)球形的等壓面，流速與到中心的距離的平方成反比，一個(gè)完全無遮擋的吸風(fēng)口，壓力傳播是整個(gè)球形空間，擴(kuò)散角為4*3.14159，由于流場為球形空間，所以流速衰變的特別快。吸風(fēng)口徑為do,當(dāng)吸風(fēng)口距離S=0.8do時(shí)流速就降為吸風(fēng)口流速uo的10%也就等于0.1uo，所以排煙罩的大小要考慮盡量靠近灶臺(tái)，要求大小尺寸合理的傘型罩子。上海嘉定區(qū)餐飲廚房通風(fēng)排煙管道價(jià)格排煙管道由于要穿過建筑梁而使管道通風(fēng)截面積變小，截面上阻力增加，造成氣流不通暢。</p><div
