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(zhǔn)備工作：

Preparation before installation:

1.圍護(hù)結(jié)構(gòu)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(tǒng)風(fēng)管安裝時(shí)，建筑物內(nèi)部安裝構(gòu)件的地面已完成，墻體混凝土已找平。需要在室內(nèi)無粉塵或防塵措施的情況下進(jìn)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(xiàn)場的輔助材料要齊全，施工技術(shù)人員應(yīng)提供質(zhì)量和技術(shù)指導(dǎo)。

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

風(fēng)管安裝注意事項(xiàng)：

Precautions for air duct installation:

1.風(fēng)管內(nèi)嚴(yán)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(huán)境中的風(fēng)管應(yīng)良好接地。穿過生活區(qū)或生產(chǎn)區(qū)的風(fēng)管一定要安裝嚴(yán)密，不得與設(shè)備風(fēng)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(fēng)管的固定不得與避雷針或房屋防雷設(shè)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(fēng)管安裝需要符合下列技術(shù)規(guī)定：

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

① 風(fēng)管與通風(fēng)設(shè)備及附件的連接配置不應(yīng)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(shè)置在出風(fēng)口、風(fēng)閥、檢查門和自動(dòng)控制機(jī)構(gòu)上，不得固定在法蘭上，以免風(fēng)管變形影響風(fēng)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(yīng)的安裝規(guī)定。懸掛風(fēng)管及部件應(yīng)設(shè)置固定點(diǎn)，防止擺動(dòng)，如固定支架、支架等。固定點(diǎn)的設(shè)置位置和數(shù)量應(yīng)根據(jù)系統(tǒng)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(jù)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(fēng)管及構(gòu)件穿墻、穿屋面時(shí)，應(yīng)設(shè)置防雨罩。當(dāng)風(fēng)管穿過屋面超過1.5m時(shí)，電纜應(yīng)鍍鋅或使用鋼絲繩。電纜不得固定在風(fēng)管法蘭或避雷針或防雷網(wǎng)絡(luò)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(yīng)具有適當(dāng)?shù)拿芊庑?，不得扭曲。柔性金屬或非金屬柔性風(fēng)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(fēng)管支吊架應(yīng)設(shè)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(shí)上，無論是末端風(fēng)管安裝還是主機(jī)的安裝，都需要經(jīng)過的方案設(shè)計(jì)，由的安裝團(tuán)隊(duì)進(jìn)行，盡量避免出現(xiàn)不必要的麻煩，耽誤施工進(jìn)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.
