1.主排煙管道通風面積

1. Ventilation area of main exhaust pipe

排煙管道有主、副之分，貫穿整個樓體的是主煙道，而副煙道是相對獨立的。據一些有經驗的師傅介紹，排煙管道主煙道的風速更好控制在15m/s以內。而大部分的廚房排煙管道安裝案例中，都是因為主煙道的通風面積不足、管道內風速又在15m/s以上引起的排煙不通暢。

There are two kinds of smoke exhaust pipes: the main flue and the auxiliary flue, which run through the whole building, are relatively independent. According to some experienced masters, it is better to control the wind speed of the main flue of the exhaust pipe within 15m / s. In most cases of kitchen smoke exhaust pipe installation, it is due to the insufficient ventilation area of the main flue, and the wind speed in the pipe is more than 15m / s, resulting in poor smoke exhaust.

2.管道通風截面積

2. Ventilation cross section of pipeline

通常廚房排煙管道安裝時，由于管道是穿過建筑梁而過，使得管道通風的橫截面積變小，導致管道內氣流不通暢。

Generally, when installing the kitchen exhaust pipe, because the pipe passes through the building beam, the cross-sectional area of the pipe ventilation becomes smaller, resulting in the air flow in the pipe is not smooth.

3.排煙管道內雜物堆積

3. Sundries accumulation in smoke exhaust pipe

廚房排煙管道安裝時，由于需要穿過建筑梁或是避開其它設備的管道，所以管道中的一段會低于整體排煙管道，這樣就會使得油水混合物或是其它雜物更容易積聚早較低的一段管道中，造成煙道堵塞的情況。

When installing the kitchen smoke exhaust pipe, because it needs to pass through the building beam or avoid the pipes of other equipment, one section of the pipe will be lower than the overall smoke exhaust pipe, which will make the oil-water mixture or other debris more likely to accumulate in the earlier and lower section of the pipe, resulting in the situation of flue blockage.

4.低層排煙不暢

4. Poor smoke exhaust at lower floor

由于商業場所的廚房主要是在一樓，不同樓層的廚房油煙通過同一主管道排出，離出口近的樓層廚房排煙效果會比較好，而樓層較低的廚房排煙效果則相對較差。

Because the kitchens of commercial places are mainly on the first floor, the smoke of kitchens on different floors is discharged through the same main pipe, and the smoke exhaust effect of kitchens on the floor near the exit is better, while the smoke exhaust effect of kitchens on the lower floor is relatively poor.
