Indoor ventilation is very important in home life or office. Ventilation system is a complete set of devices to realize the function of ventilation, including air inlet, exhaust outlet, air supply pipe, fan, cooling and heating, filter, control system and other auxiliary equipment. The following lists the differences of air duct installation in some specific applications:

1、抽油煙的通風管道安裝

1. Installation of ventilation pipe for lampblack

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，并一定要有生產廠家的合格證書以及檢驗證書，通常通風管尺寸在2000*450左右，是比較大的通風管道了。

When designing the ventilation duct for installing the range hood, the national standard shall prevail, and the manufacturer's certificate of conformity and inspection certificate must be provided. Generally, the size of the ventilation duct is about 2000*450, which is a relatively large ventilation duct.

2、浴霸通風管道安裝

2. Yuba ventilation pipe installation

安裝浴霸通風管道規格尺寸需要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。通風管道的規格在40厘米以下的，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。

The specification and size of Yuba ventilation pipe installation need to be 300*300mm, or 300*600, and its diameter is about 100 to 150. This ventilation pipe size should be selected according to the area of the home. If the size of the ventilation duct is less than 40cm, the distance between the hangers shall not be greater than 4m. If the size of the ventilation duct is more than 40cm, the distance between the hangers shall not be greater than 3m.

3、新風系統通風管安裝

3. Installation of ventilation pipe of fresh air system

新風系統主機、金屬風管都應該做保溫處理。應該在吊桿上安裝減震器；新風輸出口、排風輸出口和主機之間的連接都應該采取安裝消聲器或用軟連接來連接

The main machine of the fresh air system and the metal air duct shall be insulated. Shock absorbers should be installed on the suspenders; The connection between the fresh air outlet, exhaust air outlet and the main engine shall be installed with silencer or connected with soft connection

風管道風量計算

Air volume calculation of air duct

舉例來說：如果風管截面積：0.2048平方米，管道里氣流按20米/秒

For example: if the cross-sectional area of the air duct is 0.2048 square meters, the air flow in the duct is 20 meters / second

0.2048*20*3600=14745立方米/小時

0.2048*20*3600=14745 m3 / h

這就是這個管道需要的流量，其它照此計算

This is the flow required by this pipeline, and others are calculated according to this

通風管道內風速及風量的測定，是通過測量壓力換算得到。測得管道中氣體的真實壓力值，除了正確使用測壓儀器外，合理選擇測量斷面、減少氣流擾動對測量結果的影響很大。測量斷面應盡量選擇在氣流平穩的直管段上。

The measurement of wind speed and air volume in the ventilation duct is obtained by measuring pressure conversion. To measure the true pressure of the gas in the pipeline, in addition to the correct use of pressure measuring instruments, the reasonable selection of measuring section and the reduction of airflow disturbance have a great impact on the measurement results. The measuring section shall be selected on the straight pipe section with stable air flow as far as possible.
