酒店麻豆国产视频風機麻豆国产视频罩除消防麻豆国产视频風機麻豆视频官网的防火閥之外，考慮到酒店高溫工作的原因。其餘風機麻豆视频官网的防火閥建議安裝150℃防火閥（與平時普通風機麻豆视频官网裝置的70℃略有不同）,需關閉其餘所有風機（消防補風靠外窗及門隙等地方進風）當消防麻豆国产视频風機動作時；當開啟“排油煙風機”時，需同時（聯動）開啟“油煙罩補風風機”與“工作區新風預處理風機”。

In addition to the fire damper of the fire smoke exhaust fan pipeline, the smoke exhaust hood of the hotel smoke exhaust fan takes into account the reasons for the high temperature work of the hotel. It is recommended to install 150 ℃ fire damper on the fire damper of other fan pipes (slightly different from 70 ℃ of ordinary fan pipe devices in ordinary times), and all other fans need to be closed (the fire make-up air enters near the outer window and door gap) when the fire smoke exhaust fan operates automatically; When the "fume exhaust fan" is turned on, the "fume hood make-up fan" and the "fresh air pretreatment fan in the working area" shall be turned on at the same time (linkage).

酒店麻豆国产视频風機麻豆国产视频罩的麻豆国产视频麻豆视频官网未端需要設置麻豆国产视频閥，麻豆国产视频風機麻豆国产视频罩與麻豆国产视频麻豆视频官网連接處設置麻豆国产视频防火閥。要注意麻豆国产视频閥與麻豆国产视频防火閥是功能完全不同的設備。麻豆国产视频閥平時常關，火災時開，與報警主機聯動，開啟條件是自動報警係統發生火警（探測器報警）消防報警主機置於自動狀態，麻豆国产视频閥自動開啟，聯動麻豆国产视频風機啟動。麻豆国产视频防火閥是平時常開，火災時也是開啟狀態，但當煙氣溫度達到280℃時，麻豆国产视频防火閥自動關閉，聯動已經開啟的風機停止運行。

Smoke exhaust damper shall be set at the end of the smoke exhaust pipe of the smoke exhaust fan and smoke exhaust hood of the hotel, and smoke exhaust fire damper shall be set at the connection between the smoke exhaust fan and smoke exhaust pipe. It should be noted that smoke exhaust damper and smoke exhaust fire damper are equipment with completely different functions. The smoke exhaust valve is normally closed and opened in case of fire. It is linked with the alarm host. The opening condition is that the fire alarm host is in the automatic state in case of fire alarm (detector alarm) in the automatic alarm system, the smoke exhaust valve is automatically opened and the linked smoke exhaust fan is started. The smoke exhaust fire damper is normally open and open in case of fire, but when the flue gas temperature reaches 280 ℃, the smoke exhaust fire damper will automatically close and the linkage fan that has been opened will stop running.

對於餐飲業的廚房來說，酒店廚房麻豆国产视频罩的好處就是麻豆国产视频是否通暢，直接關係到廚房能否正常工作，油煙淨化則隻是廚房麻豆国产视频係統中的一個淨化空氣的強製性功能。麻豆国产视频係統和淨化器的合理匹配是保證油煙淨化器淨化效率的關鍵，同時也是油煙淨化器設計人員容易忽略的問題，如果麻豆国产视频係統設計不合理而造成整個廚房麻豆国产视频不暢，則將無法安裝油煙淨化器，即使安裝了油煙淨化器也無法正常工作。

Whether the smoke exhaust hood can purify the air in the kitchen of the hotel is directly related to the normal function of the kitchen smoke exhaust system. The reasonable matching of smoke exhaust system and purifier is the key to ensure the purification efficiency of oil fume purifier. At the same time, it is also a problem easy to be ignored by the designers of oil fume purifier. If the design of smoke exhaust system is unreasonable and the smoke exhaust of the whole kitchen is not smooth, the oil fume purifier will not be installed, and even if the oil fume purifier is installed, it will not work normally.
