你知道通風(fēng)風(fēng)管設(shè)計前有什么需要注意的嗎？

1.  通風(fēng)管的資料一般選用鍍鋅板（俗稱白鐵皮），也可選用玻璃鋼、塑料風(fēng)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.  通風(fēng)口設(shè)置在實際需要降溫的當(dāng)?shù)兀L(fēng)口規(guī)劃風(fēng)量即便以其要降溫當(dāng)?shù)厮璧?通風(fēng)量，風(fēng)口標(biāo)準(zhǔn)可依據(jù)風(fēng)量與風(fēng)口風(fēng)速來斷定， 通風(fēng)口材質(zhì)可選用塑料或鋁合金等制品。

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.

出風(fēng)口風(fēng)咀方式可依據(jù)實際情況選用多種方式，引薦挑選錦煜空調(diào)專用風(fēng)咀，風(fēng)口喉部均勻流速控制在3-6m/s，（引薦選用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.  通風(fēng)管的標(biāo)準(zhǔn)一般選用假定流速法規(guī)劃，主風(fēng)管堅持在8-10m/s，支風(fēng)管6-8m/s，較末端風(fēng)管堅持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. 所規(guī)劃的風(fēng)管總體上要求既經(jīng)濟又能到達較低的風(fēng)阻和噪聲，使錦煜冷風(fēng)機的 通風(fēng)量盡量到達較大值，風(fēng)管曲折半徑一般不小于風(fēng)管直徑的兩倍，以削減管通風(fēng)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.  通風(fēng)管道的長度應(yīng)依據(jù)不同型號的錦煜空調(diào)風(fēng)壓不同的特色進行規(guī)劃

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

6. 所規(guī)劃的管道盡量取直，防止不必要的拐彎和分支管，以削減管道局部阻力

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. 從平面布置和經(jīng)濟角度上考慮，能不用風(fēng)管的當(dāng)?shù)鼐筒挥蔑L(fēng)管，有必要使用風(fēng)管的當(dāng)?shù)乇M量把風(fēng)管規(guī)劃短些

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. 較長管道依據(jù)風(fēng)量規(guī)劃成多段不同標(biāo)準(zhǔn)的風(fēng)管，選用變徑管銜接，變徑管的設(shè)置不宜過多，一般整根不超越四個，變徑管長由“>2（D-d）”來斷定

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.  通風(fēng)管道與錦煜冷風(fēng)機主機出風(fēng)口銜接處應(yīng)密封好；室外管道過長宜規(guī)劃保溫，室內(nèi)管道一般不須保溫

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. 若在規(guī)劃中存在支分管，則須在支管上裝設(shè)閥門或分風(fēng)擋板以調(diào)理風(fēng)量，使支管風(fēng)量到達規(guī)劃值。

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.
