Now the ventilation pipe can be seen everywhere in our daily life and industry, and its application is more and more widely. Maybe some people don't know what the ventilation pipe can help us. It doesn't matter. The ventilation pipe manufacturer will explain it to you slowly, and I believe we will understand it after listening to it.

每家的廚房里都有煙道，一起煙道也有主副之分，主煙道貫穿整個樓體，而副煙道是相對獨立的。通常家里的油煙會先到副煙道里，然后再經過隔板上的孔進入主煙道，這樣可保證每戶的油煙是阻隔開來的。主煙道底層有一補風口。

Every kitchen has a flue, and there are main and auxiliary flue together. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Usually, the lampblack in the house goes to the auxiliary flue first, and then goes into the main flue through the hole on the partition board, so as to ensure that the lampblack of each household is blocked. There is a make-up air outlet at the bottom of the main flue.

其原理是經過抽油煙機將煙氣推入次煙道中，用抽油煙機推動力和油煙溫度上浮力使油煙上升一段距離后再進入主煙道排出屋面,外加不銹鋼煙道裝飾板，煙道口可改入吊頂內。

The principle is that the flue gas is pushed into the secondary flue by the range hood, and then the flue gas rises for a certain distance by the driving force of the range hood and the buoyancy of the temperature of the flue gas, and then enters the main flue to discharge the roof, and the stainless steel flue decorative plate is added, and the flue port can be changed into the ceiling.

由于廚房地點建筑物的格局以及廚房在建筑物中位置不一樣，有條件的廚房應由建筑物的會集空調體系進行有序送風。但目前所遇到的大多數情況是建筑物沒有設置廚房的送風體系。

Due to the different layout of the building and the different position of the kitchen in the building, the conditional kitchen should be orderly supplied by the centralized air conditioning system of the building. But at present, most of the situation is that there is no kitchen air supply system in the building.

許多帶餐廳、廚房等的建筑物，僅規劃了會集采暖體系而無會集空調體系。當廚房處于工作狀況時，排風體系投入運轉，廚房內處于負壓狀況，新風來歷包含室外新風浸透和餐廳的空氣很多補入廚房。

Many buildings with restaurants, kitchens and so on are only planned with centralized heating system but no centralized air conditioning system. When the kitchen is in the working condition, the exhaust system is put into operation, and the kitchen is in the negative pressure condition. The origin of fresh air includes outdoor fresh air infiltration and a lot of restaurant air into the kitchen.

以上就是通風管道在廚房的應用，正因為有了通風管道，廚房才少了油煙，通風管道給我們的生活帶來了很多的便利。

The above is the application of ventilation pipe in the kitchen. Because of the ventilation pipe, the kitchen has less oil smoke, and the ventilation pipe has brought a lot of convenience to our life.
