你知道通风风管设计前有什么需要注意的吗？

1.  通风管的资料一般选用镀锌板（俗称白铁皮），也可选用玻璃钢、塑料风管等

1. Galvanized sheet (commonly known as white iron sheet) and glass fiber reinforced plastics (FRP) and plastic air ducts are generally used for the information of ventilation ducts.

2.  通风口设置在实际需要降温的当地，风口规划风量即便以其要降温当地所需的 通风量，风口标准可依据风量与风口风速来断定， 通风口材质可选用塑料或铝合金等制品。

2. The ventilation outlet is set in the place where the actual temperature needs to be lowered. The ventilation outlet planning air volume can be determined according to the air volume and the air velocity of the ventilation outlet. The material of the ventilation outlet can be made of plastic or aluminium alloy.

出风口风咀方式可依据实际情况选用多种方式，引荐挑选锦煜空调专用风咀，风口喉部均匀流速控制在3-6m/s，（引荐选用4-5m/s的流速）

The outlet air nozzle can be selected in many ways according to the actual situation. Jinyu air conditioning special air nozzle can be recommended. The uniform flow rate of the outlet throat can be controlled at 3-6m/s. (4-5m/s is recommended.)

3.  通风管的标准一般选用假定流速法规划，主风管坚持在8-10m/s，支风管6-8m/s，较末端风管坚持4-6m/s

3. The standard of ventilation duct generally adopts the assumed velocity method. The main duct sticks to 8-10m/s, the branch duct 6-8m/s, and the end duct sticks to 4-6m/s.

4. 所规划的风管总体上要求既经济又能到达较低的风阻和噪声，使锦煜冷风机的 通风量尽量到达较大值，风管曲折半径一般不小于风管直径的两倍，以削减管通风阻力

4. The planned ducts generally require both economical and minimal wind resistance and noise to maximize the ventilation capacity of Jinyu air cooler. The winding radius of ducts is not less than twice the diameter of ducts in order to reduce the duct ventilation resistance.

5.  通风管道的长度应依据不同型号的锦煜空调风压不同的特色进行规划

5. The length of ventilation duct should be planned according to the different characteristics of air pressure of Jinyu air conditioner.

6. 所规划的管道尽量取直，防止不必要的拐弯和分支管，以削减管道局部阻力

6. The planned pipeline should be straightened as far as possible to prevent unnecessary bending and branching so as to reduce the local resistance of the pipeline.

7. 从平面布置和经济角度上考虑，能不用风管的当地就不用风管，有必要使用风管的当地尽量把风管规划短些

7. From the perspective of layout and economy, if you can use ducts locally, you will not need ducts. It is necessary to use ducts locally to plan the ducts as short as possible.

8. 较长管道依据风量规划成多段不同标准的风管，选用变径管衔接，变径管的设置不宜过多，一般整根不超越四个，变径管长由“>2（D-d）”来断定

8. Long pipes are planned to be multi-section and different standard air pipes according to air volume. Variable-diameter pipes are selected to connect with each other. The installation of variable-diameter pipes should not be too much. Generally, the whole pipe should not exceed four. The length of variable-diameter pipes is determined by ">2(D-d)".

9.  通风管道与锦煜冷风机主机出风口衔接处应密封好；室外管道过长宜规划保温，室内管道一般不须保温

9. The joint of ventilation duct and outlet of Jinyu chiller should be sealed well; the outdoor duct should be planned for insulation when it is too long, and the indoor duct should not be insulated generally.

10. 若在规划中存在支分管，则须在支管上装设阀门或分风挡板以调理风量，使支管风量到达规划值。

10. If there are branch pipes in the planning, valves or distributor baffles shall be installed on the branch pipes to regulate the air flow so that the branch pipe air flow reaches the planning value.
