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。（2）將組合式空調(diào)機(jī)組的新風(fēng)一部分直接補(bǔ)入廚房，一部分送入餐廳，并通過(guò)回風(fēng)機(jī)回到空調(diào)機(jī)。這樣可以部分解決新風(fēng)能耗大的問(wèn)題，同時(shí)使用的靈活性也較大?？稍趶N房設(shè)置測(cè)壓裝置，當(dāng)廚房排風(fēng)機(jī)全部工作時(shí)，負(fù)壓增大，則回風(fēng)電動(dòng)閥關(guān)閉，回風(fēng)機(jī)停，餐廳送風(fēng)大量補(bǔ)入廚房；當(dāng)少部分排風(fēng)機(jī)開(kāi)啟或排風(fēng)機(jī)不工作時(shí)，負(fù)壓不是很大，則回風(fēng)電動(dòng)閥打開(kāi)，回風(fēng)機(jī)啟動(dòng)，避免空調(diào)送風(fēng)全部被排出。（3）用兩臺(tái)機(jī)組分別為餐廳、廚房服務(wù)，其中廚房為全新風(fēng)直流系統(tǒng)，直接補(bǔ)充廚房爐灶的排風(fēng)，而餐廳為一次回風(fēng)全新空氣系統(tǒng)，這個(gè)方案能保證餐廳和廚房的空調(diào)效果，而且廚房和餐廳系統(tǒng)互不干擾，缺點(diǎn)是初投資較大。4集氣（煙）罩集氣（煙）罩一般采用整體加工，包括過(guò)濾、集油、集水等設(shè)備，多為專(zhuān)業(yè)公司制作。其外形應(yīng)統(tǒng)一、美觀、易于清理，廚房通風(fēng)中，需補(bǔ)充一定數(shù)量的新風(fēng)，一方面可以平衡氣壓，避免廚房負(fù)壓過(guò)大（一般不應(yīng)大于5Pa），另一方面可以降低廚房?jī)?nèi)的溫度，改善工作環(huán)境。對(duì)于烹飪油煙的收集，采用的集氣（煙）罩主要有三種類(lèi)別：（1）簡(jiǎn)易不含擋油板和送風(fēng)設(shè)備的集氣罩適合各種靈活機(jī)動(dòng)場(chǎng)所，便于加工安裝。西北電子暖通設(shè)備安裝施工商實(shí)驗(yàn)室潔凈區(qū)壓差調(diào)節(jié)。</p><div

不同樓層的廚房油煙通過(guò)同一主管道排出，離出口近的樓層廚房排煙效果較好，而較低樓層的廚房排煙不通暢。6排煙風(fēng)機(jī)常用的排煙風(fēng)機(jī)有軸流風(fēng)機(jī)、風(fēng)機(jī)箱和離心風(fēng)機(jī)3種。（1）軸流風(fēng)機(jī)以前應(yīng)用較多，但由于全壓小，在安裝油煙凈化器后很少應(yīng)用。（2）風(fēng)機(jī)箱全壓中等，風(fēng)量可以調(diào)節(jié)，且噪聲較低，常在集煙罩距油煙排放口距離中等的廚房排煙系統(tǒng)中選用。（3）離心風(fēng)機(jī)全壓和風(fēng)量都可以調(diào)節(jié)，但由于噪聲較大，常需要做降噪處理。當(dāng)廚房位于建筑物的底部時(shí)其排風(fēng)機(jī)宜安放在屋頂，一方面可減少室內(nèi)噪聲污染，同時(shí)排風(fēng)風(fēng)道處于負(fù)壓狀態(tài)，可避免氣味外溢。風(fēng)機(jī)安放在屋頂時(shí)，一般選擇離心風(fēng)機(jī)。7結(jié)語(yǔ)廚房排煙系統(tǒng)的合理設(shè)計(jì)是后續(xù)加裝油煙凈化裝置的前提條件。本文分析了廚房排煙系統(tǒng)中的各個(gè)組成部分，提出了廚房理論排煙風(fēng)量的計(jì)算方法以及集氣罩、排風(fēng)管道和排風(fēng)機(jī)的設(shè)計(jì)選型原則，可用以指導(dǎo)飲食業(yè)油煙凈化器的選型，提高油煙凈化器的凈化效率。實(shí)驗(yàn)室廢氣系統(tǒng)處理工程。貴州光學(xué)暖通設(shè)備安裝調(diào)試</p><p
