說到食堂，就會想到食堂麻豆国产视频罩。 呼吸著油煙的大個子特別吸睛。 下麵說說食堂通風櫃麻豆国产视频量的確定和設計。

When it comes to the canteen, you will think of the smoke exhaust hood of the canteen. The big man who breathed the lampblack was very eye - catching. Let's talk about the determination and design of the smoke exhaust volume of the fume hood in the canteen.

為保證淨化效果，在實際設計中，排風量嚴格按照食堂麻豆国产视频罩和抽麻豆国产视频罩的抽風風速計算，抽麻豆国产视频罩的抽風風速通常不小於 0.5米/秒。 很小排風量通常由下式計算：L=2000PH

In order to ensure the purification effect, in the actual design, the exhaust air volume is calculated in strict accordance with the exhaust wind speed of the canteen exhaust hood and the exhaust hood. The exhaust wind speed of the exhaust hood is usually not less than 0.5 m / s. Very small exhaust air volume is usually calculated by the following formula: l=2000ph

式中：L——食堂通風櫃排風量，m3/h；

Where: L - exhaust air volume of canteen ventilator, m3/h;

P——食堂麻豆国产视频罩口周長（靠牆側不計），m；

P - perimeter of smoke exhaust hood of canteen (not counting the side near the wall), m;

H——食堂麻豆国产视频罩口到爐口的距離，m。

H - distance from smoke exhaust hood of canteen to furnace mouth, M.

用上式計算排風量，再根據食堂麻豆国产视频罩的麵積計算抽麻豆国产视频罩的抽風速度，保證抽麻豆国产视频罩的抽風速度不小於0.5m/s。

Use the above formula to calculate the exhaust volume, and then calculate the exhaust speed of the exhaust hood according to the area of the canteen exhaust hood, so as to ensure that the exhaust speed of the exhaust hood is not less than 0.5m/s.

在實際工程設計中，經常使用估算法。 根據《民用建築暖通空調設計技術辦法》中對廚房通風量的規定，廚房通風量也可按以下通風次數確定：

Estimation method is often used in practical engineering design. According to the provisions on the kitchen ventilation volume in the technical measures for HVAC design of civil buildings, the kitchen ventilation volume can also be determined according to the following ventilation times:

中式廚房：L=40-50（次/小時）；

Chinese Kitchen: l=40-50 (times / hour);

西廚：L=30-40（次/h）；

Western Kitchen: l=30-40 (times /h);

員工餐廳：L=25-35（次/小時）。

Staff restaurant: l=25-35 (times / hour).
