In densely populated areas, ventilation ducts are generally required, mainly used for fresh air in spring and autumn, cooling in summer, and heating in winter. How much do you know about the specifications for air duct installation

安裝前的準備工作：

Preparation before installation:

1.圍護結構施工完畢，所有障礙物、雜物清理完畢，地面雜物清理完畢!

1. The construction of the enclosure structure is completed, all obstacles and debris are cleared, and the ground debris is cleared!

2.凈化系統風管安裝時，建筑物內部安裝構件的地面已完成，墻體混凝土已找平。需要在室內無粉塵或防塵措施的情況下進行。

When installing the air duct of the purification system, the ground of the internal installation components of the building has been completed, and the wall concrete has been leveled. It needs to be carried out indoors without dust or dust prevention measures.

3.安裝現場的輔助材料要齊全，施工技術人員應提供質量和技術指導。

3. The auxiliary materials on the installation site should be complete, and construction technicians should provide quality and technical guidance.

風管安裝注意事項：

Precautions for air duct installation:

1.風管內嚴禁與其他管道交叉

1. It is strictly prohibited to cross with other pipelines inside the air duct

2.安裝在易燃易爆環境中的風管應良好接地。穿過生活區或生產區的風管一定要安裝嚴密，不得與設備風管接口。

2. Air ducts installed in flammable and explosive environments should be well grounded. Air ducts passing through living or production areas must be installed tightly and must not interface with equipment air ducts.

3.室外垂直風管的固定不得與避雷針或房屋防雷設施連接。

3. The fixation of outdoor vertical air duct shall not be connected with lightning rod or lightning protection facilities of the house.

4.風管安裝需要符合下列技術規定：

4. The installation of air ducts needs to comply with the following technical regulations:

① 風管與通風設備及附件的連接配置不應減少其連接部位的連接管。

① The connection configuration between air ducts, ventilation equipment, and accessories should not reduce the number of connecting pipes at their connection points.

② 吊架不得設置在出風口、風閥、檢查門和自動控制機構上，不得固定在法蘭上，以免風管變形影響風管功能。

② Hangers shall not be installed on air vents, air valves, inspection doors, and automatic control mechanisms, nor shall they be fixed on flanges to prevent deformation of the air duct from affecting its function.

③ 吊架安裝一定符合相應的安裝規定。懸掛風管及部件應設置固定點，防止擺動，如固定支架、支架等。固定點的設置位置和數量應根據系統條件確定。

③ The installation of the hanger must comply with the corresponding installation regulations. Hanging air ducts and components should be equipped with fixed points to prevent swinging, such as fixed brackets, brackets, etc. The location and quantity of fixed points should be determined based on system conditions.

④ 法蘭墊片和厚度根據輸送空氣的溫度而不同。

④ The flange gasket and thickness vary depending on the temperature of the air being transported.

⑤ 風管及構件穿墻、穿屋面時，應設置防雨罩。當風管穿過屋面超過1.5m時，電纜應鍍鋅或使用鋼絲繩。電纜不得固定在風管法蘭或避雷針或防雷網絡上。

⑤ When air ducts and components pass through walls or roofs, rain covers should be installed. When the air duct passes through the roof for more than 1.5m, the cable should be galvanized or steel wire rope should be used. The cable shall not be fixed on the air duct flange or lightning rod or lightning protection network.

⑥ 柔性短管的安裝應具有適當的密封性，不得扭曲。柔性金屬或非金屬柔性風管長度不得超過2m，不得有死彎和塌陷。

⑥ The installation of flexible short pipes should have appropriate sealing and should not be twisted. The length of flexible metal or non-metallic flexible air ducts shall not exceed 2m, and there shall be no dead bends or collapses.

⑦ 保溫風管支吊架應設置在保溫層外，不得損壞保溫層。

⑦ The insulation air duct support and hanger should be installed outside the insulation layer and should not damage the insulation layer.

事實上，無論是末端風管安裝還是主機的安裝，都需要經過的方案設計，由的安裝團隊進行，盡量避免出現不必要的麻煩，耽誤施工進度。

In fact, whether it is the installation of terminal air ducts or the installation of hosts, it requires expert design and professional installation teams to avoid unnecessary trouble and delay the construction progress as much as possible.
