Pipeline and construction pipeline should pay attention to the operation specification in the construction. The use of ventilation pipeline in family buildings also needs to meet certain construction standards. For the construction process of air duct, the type of air duct is generally selected according to the design level. At the same time, in the design, it is necessary to refer to the construction environment and the difficulty of the role, and estimate the layout design of the ventilation pipeline.

因為風管資料是鍍鋅板或者是金屬資料，在施工時要嚴厲按照施工驗收標準選擇鋼板厚度和施工工藝，比如風管制造偏差、平直度、風管加固、支吊架選擇及制造裝置等等。到了施工階段，出風口盡量不要靠近設備。

Because the air duct information is galvanized sheet or metal information, the steel plate thickness and construction technology should be strictly selected according to the construction acceptance standard, such as the air duct manufacturing deviation, straightness, air duct reinforcement, support selection and manufacturing device, etc. At the construction stage, the air outlet should not be close to the equipment as far as possible.

假如可以添加彎頭數目也可以下降噪音，風口加裝過濾網，噪音操控效果也很好。 風機的聲響。處理辦法我們通常可裝消聲器處理風管中風的沖突聲。通常在設計階段就要思考噪聲的問題，設計操控好管內風速，防止風聲嘯叫，以下是一些經歷。

If the number of elbows can be added, the noise can also be reduced. If the air outlet is equipped with a filter, the noise control effect is also very good. The sound of the fan. How to deal with it we can usually install a muffler to deal with the conflicting sound of the wind in the air duct. Usually in the design stage, we need to consider the problem of noise, design and control the wind speed in the pipe to prevent the wind from whistling. Here are some experiences.

1、螺旋風管風道轉角盡量削減。

1. The angle of spiral duct should be reduced as much as possible.

2、軟接頭裝置標準，防止軟接帆布松垮發生風阻而形成風噪。

2. The standard of flexible joint device can prevent wind resistance and wind noise caused by loose canvas.

3、螺旋風管風機葉輪體系動平衡校調合理正常正負不大于5絲的起伏。

3. The dynamic balance adjustment of spiral duct fan impeller system is reasonable, and the fluctuation of positive and negative is no more than 5 threads.

4、操控出風、回風間隔，防止空氣對流時自激表象和小循環空間。

4. Control the air outlet and return air interval to prevent the self-excited appearance and small circulation space during air convection.

5、懸掛選用順便彈簧避震專職的連接器，減輕運轉時因扭力發生的跳動或共頻。

5. The suspension adopts the spring shock absorber connector to reduce the runout or common frequency caused by torsion during operation.

通過設計能夠很好的規劃出管道的界限，這樣也能夠為其他的系統提供可靠的保障。而且設計布局更加合理，也能夠增加建筑的溫馨指數，可謂是一勞多益

The pipeline boundary can be well planned through the design, which can also provide reliable guarantee for other systems. Moreover, the design layout is more reasonable, which can also increase the warmth index of the building
