廚房排煙風(fēng)機(jī)排煙罩除消防排煙風(fēng)機(jī)管道的防火閥之外，考慮到廚房高溫工作的原因。其余風(fēng)機(jī)管道的防火閥建議安裝150℃防火閥（與平時(shí)普通風(fēng)機(jī)管道裝置的70℃略有不同）,需關(guān)閉其余所有風(fēng)機(jī)（消防補(bǔ)風(fēng)靠外窗及門隙等地方進(jìn)風(fēng)）當(dāng)消防排煙風(fēng)機(jī)動(dòng)作時(shí)；當(dāng)開啟“排油煙風(fēng)機(jī)”時(shí)，需同時(shí)（聯(lián)動(dòng)）開啟“油煙罩補(bǔ)風(fēng)風(fēng)機(jī)”與“工作區(qū)新風(fēng)預(yù)處理風(fēng)機(jī)”。
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(shí)常關(guān)，火災(zāi)時(shí)開，與報(bào)警主機(jī)聯(lián)動(dòng)，開啟條件是自動(dòng)報(bào)警系統(tǒng)發(fā)生火警（探測器報(bào)警）消防報(bào)警主機(jī)置于自動(dòng)狀態(tài)，排煙閥自動(dòng)開啟，聯(lián)動(dòng)排煙風(fēng)機(jī)啟動(dòng)。排煙防火閥是平時(shí)常開，火災(zāi)時(shí)也是開啟狀態(tài)，但當(dāng)煙氣溫度達(dá)到280℃時(shí)，排煙防火閥自動(dòng)關(guān)閉，聯(lián)動(dòng)已經(jīng)開啟的風(fēng)機(jī)停止運(yùn)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(jì)南廚房排煙
Jinan kitchen smoke exhaust
濟(jì)南廚房排煙使用說明：一般用于廚房的風(fēng)機(jī)排煙罩有會(huì)帶走廚房大量空氣，油煙罩補(bǔ)風(fēng)風(fēng)機(jī)—抽油煙時(shí)，需向廚房補(bǔ)充空氣，該機(jī)提供約占排油煙風(fēng)量的80%。工作區(qū)新風(fēng)預(yù)處理風(fēng)機(jī)—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(fēng)。該機(jī)提供約占排油煙風(fēng)量的20%排油煙風(fēng)機(jī)—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(jìn)行有序送風(fēng)。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(fēng)系統(tǒng)。許多帶餐廳、廚房等的建筑物,僅設(shè)計(jì)了集中采暖系統(tǒng)而無集中空調(diào)系統(tǒng)。當(dāng)廚房處于工作狀態(tài)時(shí),排風(fēng)系統(tǒng)投入運(yùn)行,廚房內(nèi)處于負(fù)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(xiàng)目,在設(shè)要充分考慮安裝了油煙凈化器后對排風(fēng)系統(tǒng)的影響;如果是改造項(xiàng)目,在加裝油煙凈化器時(shí)需要對排風(fēng)系統(tǒng)重新進(jìn)行核算,必要時(shí)要對集煙罩、排煙管道和廚房整體補(bǔ)風(fēng)裝置進(jìn)行改造并更換排煙風(fēng)機(jī)。
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(fēng)量的確定 為了保證凈化效果,在實(shí)際設(shè)排煙風(fēng)量要求嚴(yán)格按照排風(fēng)罩的吸入風(fēng)速計(jì)算,罩口的吸風(fēng)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(fēng)系統(tǒng)宜采用變速風(fēng)機(jī)或關(guān)聯(lián)又風(fēng)機(jī)進(jìn)行送排風(fēng)。送排風(fēng)口布置:廚房內(nèi)送、排風(fēng)口的布置應(yīng)按灶具的具體位置加以考慮,不要讓送風(fēng)射流擾亂灶具的排風(fēng)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
