In our home life or office, indoor ventilation is very important. If the ventilation is not good, people who have been inside for a long time will feel anoxic and uncomfortable, which will affect their normal work and life. Therefore, the installation of ventilation pipes is very important. The following section will introduce the installation problems and precautions of the ventilation duct for you. I hope it can help you.

通風管道要求—抽油煙的通風管道安裝

Requirements for ventilation duct - installation of ventilation duct for lampblack extraction

如果是要安裝抽油煙機的通風管道，在進行設計的時候，要以國家的標準為準，并要定要有生產廠家的合格證書以及檢驗證書，如果通風管道沒有達到國家規定的設計標準，那么在使用的過程中，很容易就會發生安全事故，造成不必要的危害。通風管尺寸在2000*450左右，是比較大的通風管道了。

If the ventilation pipe of the range hood is to be installed, the national standard shall prevail during the design, and the manufacturer's certificate of conformity and inspection certificate shall be required. If the ventilation pipe fails to meet the national design standard, it is easy to have safety accidents and cause unnecessary hazards during the use process. The size of ventilation pipe is about 2000 * 450, which is a relatively large ventilation pipe.

通風管道要求—浴霸通風管道安裝

Ventilation duct requirements - Yuba ventilation duct installation

如果要選擇安裝浴霸通風管道的話，其規格尺寸需要300*300mm，或者300*600，其直徑大概是在100到150之間，這個通風管道尺寸還是要根據家里的面積來選購一款大小合適的通風管道。而根據國家標準，通風管道的規格在40厘米一下的，其吊架的距離不得大于4米，如果通風管道規格是在40厘米以上的，其吊架的距離不得大于3米。

If you want to install Yuba ventilation duct, its specification and size need to be 300 * 300mm, or 300 * 600, and its diameter is about 100 to 150. The size of the ventilation duct should be selected according to the size of the home. According to the national standard, if the specification of the ventilation pipe is less than 40cm, the distance of the hanger shall not be more than 4m. If the specification of the ventilation pipe is more than 40cm, the distance of the hanger shall not be more than 3m.

通風管道要求—通風管道尺寸要測量好

Requirements for ventilation duct - the size of ventilation duct shall be measured

通風管道尺寸要計算好，其方法就是風管的橫截面積乘以風管的風速再乘以3600，計算出來的結構就是通風管道的尺寸了，其中風管的風速更好不要超過15米每秒，好的風速就是8到12米每秒為好。在安裝通風管道的時候，風管的兩端應該轉動靈活，不得有明顯的劃痕。

The size of the air duct shall be calculated by multiplying the cross-sectional area of the air duct by the wind speed of the air duct and then by 3600. The calculated structure is the size of the air duct. The wind speed of the air duct should not exceed 15 meters per second. A good wind speed is 8 to 12 meters per second. When installing the air duct, both ends of the air duct shall rotate flexibly without obvious scratches.

通風管道注意—要注意通風管道的材料

Attention to ventilation duct - pay attention to the material of ventilation duct

通風管道的材料比較多，比如鋼板風管、玻璃鋼通風管道、復合材料通風管道、塑料通風管道、不銹鋼通風管、單面彩鋼通風管等等。而從用途上來看，有可以分為工業排風通風管道、凈化系統通風管道、空調通風管道、瓦斯通風管道等等。形狀不同，通風管道類型也不一樣。

There are many materials for ventilation ducts, such as steel plate air ducts, glass fiber reinforced plastic air ducts, composite material air ducts, plastic air ducts, stainless steel air ducts, single-sided color steel air ducts, etc. From the use point of view, it can be divided into industrial ventilation ducts, purification system ventilation ducts, air conditioning ventilation ducts, gas ventilation ducts and so on. Different shapes lead to different types of ventilation ducts.
