廚房排煙風機排煙罩除消防排煙風機管道的防火閥之外，考慮到廚房高溫工作的原因。其余風機管道的防火閥建議安裝150℃防火閥（與平時普通風機管道裝置的70℃略有不同）,需關(guān)閉其余所有風機（消防補風靠外窗及門隙等地方進風）當消防排煙風機動作時；當開啟“排油煙風機”時，需同時（聯(lián)動）開啟“油煙罩補風風機”與“工作區(qū)新風預(yù)處理風機”。
In addition to the fire damper of the fire exhaust fan pipe, the high temperature operation of the kitchen is considered. It is recommended to install 150 ℃ fire damper for other fan pipes (slightly different from the 70 ℃ of ordinary fan duct installation), It is necessary to turn off all other fans (the fire-fighting make-up air is close to the external windows and door gaps) when the fire-fighting smoke exhaust fan is in operation; when the "oil fume exhaust fan" is turned on, the "oil fume hood make-up fan" and the "fresh air pretreatment fan in the working area" should be started simultaneously (linkage).
排煙閥平時常關(guān)，火災(zāi)時開，與報警主機聯(lián)動，開啟條件是自動報警系統(tǒng)發(fā)生火警（探測器報警）消防報警主機置于自動狀態(tài)，排煙閥自動開啟，聯(lián)動排煙風機啟動。排煙防火閥是平時常開，火災(zāi)時也是開啟狀態(tài)，但當煙氣溫度達到280℃時，排煙防火閥自動關(guān)閉，聯(lián)動已經(jīng)開啟的風機停止運行。

The smoke exhaust valve is normally closed at ordinary times and opened in case of fire, which is linked with the alarm host. The opening condition is that the automatic alarm system has a fire alarm (detector alarm), the fire alarm host is in automatic state, the smoke exhaust valve is opened automatically, and the linkage smoke exhaust fan is started. The smoke exhaust fire damper is normally open at ordinary times and is also open in case of fire. However, when the flue gas temperature reaches 280 ℃, the smoke fire damper will automatically close and the fan that has been opened will stop running.
濟南廚房排煙
Jinan kitchen smoke exhaust
濟南廚房排煙使用說明：一般用于廚房的風機排煙罩有會帶走廚房大量空氣，油煙罩補風風機—抽油煙時，需向廚房補充空氣，該機提供約占排油煙風量的80%。工作區(qū)新風預(yù)處理風機—為廚房工作區(qū)（人員工作位置）提供經(jīng)過預(yù)處理的新風。該機提供約占排油煙風量的20%排油煙風機—排去煮食區(qū)油煙罩的油氣。
Jinan kitchen smoke exhaust instructions: generally used in the kitchen fan exhaust hood will take away a large amount of kitchen air, lampblack hood air supplement fan - when pumping oil smoke, it needs to supplement air to the kitchen, which provides about 80% of the oil fume exhaust volume. Working area fresh air pre-treatment fan - provides pre-treatment fresh air for kitchen work area (staff working position). This machine provides about 20% of the oil fume exhaust air volume, which exhausts the oil and gas from the cooking area hood.
廚房所在建筑物的格局以及廚房在建筑物中的位置不同,有條件的廚房應(yīng)由建筑物的集中空調(diào)系統(tǒng)進行有序送風。但目前所遇到的大部分情況是建筑物沒有設(shè)置廚房的送風系統(tǒng)。許多帶餐廳、廚房等的建筑物,僅設(shè)計了集中采暖系統(tǒng)而無集中空調(diào)系統(tǒng)。當廚房處于工作狀態(tài)時,排風系統(tǒng)投入運行,廚房內(nèi)處于負壓狀態(tài)。
Due to the different structure of the building where the kitchen is located and the location of the kitchen in the building, the centralized air conditioning system of the building should be used for orderly air supply in the kitchen with conditions. But at present, most of the situation is that there is no kitchen air supply system in the building. Many buildings with restaurants, kitchens and so on have only designed central heating system without central air conditioning system. When the kitchen is in working state, the exhaust system is put into operation, and the kitchen is in a negative pressure state.
如果是新建項目,在設(shè)要充分考慮安裝了油煙凈化器后對排風系統(tǒng)的影響;如果是改造項目,在加裝油煙凈化器時需要對排風系統(tǒng)重新進行核算,必要時要對集煙罩、排煙管道和廚房整體補風裝置進行改造并更換排煙風機。
If it is a new project, the impact of the installation of oil fume purifier on the exhaust system should be fully considered in the design; if it is a reconstruction project, the exhaust system needs to be recalculated when the oil fume purifier is installed, and if necessary, the smoke collecting hood, smoke exhaust pipe and kitchen integral air supplement device shall be reconstructed and the smoke exhaust fan shall be replaced.
廚房油煙排風量的確定 為了保證凈化效果,在實際設(shè)排煙風量要求嚴格按照排風罩的吸入風速計算,罩口的吸風速度通常不低于0.5m/s。
In order to ensure the purification effect, in the actual design, the exhaust air volume should be calculated in strict accordance with the suction wind speed of the exhaust hood, and the suction speed of the hood mouth is usually not less than 0.5m/s.
廚房的通風系統(tǒng)宜采用變速風機或關(guān)聯(lián)又風機進行送排風。送排風口布置:廚房內(nèi)送、排風口的布置應(yīng)按灶具的具體位置加以考慮,不要讓送風射流擾亂灶具的排風性通
The ventilation system of kitchen should adopt variable speed fan or associated fan for air supply and exhaust. Air supply and exhaust outlet arrangement: the arrangement of air supply and exhaust outlets in the kitchen should be considered according to the specific position of the stove, and the air supply jet should not disturb the ventilation performance of the stove 上一篇：通風管道有哪些機械通風原則呢？
