1. 送風管的材料一般選用鍍鋅板(俗稱白鐵皮)，也可選用玻璃鋼、塑料風管等

1. Galvanized sheet (commonly known as white iron sheet) is usually used as the material of air duct, and glass fiber reinforced plastic and plastic air duct are also used.

2. 送風口設置在實際需要降溫的當地，風口規劃風量即便以其要降溫當地所需的送風量，風口標準可依據風量與風口風速來斷定，送風口原料可選用塑料或鋁合金等制品，出風口風咀形式可依據實際情況選用多種形式，挑選錦煜空調專用風咀，風口喉部均勻流速控制在3-6m/s，(選用4-5m/s的流速)

2. The air outlet is set in the place where the actual cooling is needed. Even if the air outlet planning air volume is needed to cool down the local air supply volume, the air outlet standard can be determined according to the air volume and air velocity. The raw materials of the air outlet can be selected by plastics or aluminium alloy products. The air outlet nozzle form can be selected by various forms according to the actual situation. It is recommended that the special air outlet nozzle for Jinyu air conditioning be selected and that the air outlet throat is uniformly flowing. Speed control is 3-6m/s. (4-5m/s is recommended.)

3. 送風管的標準一般選用假定流速法規劃，主風管堅持在8-10m/s，支風管6-8m/s，較末端風管堅持4-6m/s

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

4. 所規劃的風管總體上要求既經濟又能到達較低的風阻和噪聲，使錦煜冷風機的送風量盡量到達較大值，風管曲折半徑一般不小于風管直徑的兩倍，以削減管通風阻力

4. The planned ducts are generally economical and can reach the lowest wind resistance and noise, so as to maximize the air supply capacity of Jinyu air cooler, and the winding radius of ducts is not less than twice the diameter of ducts, so as to reduce the resistance of ducts to ventilation.

5. 送風管道的長度應依據不同型號的錦煜空調風壓不同的特色進行規劃

5. The length of air supply pipeline should be planned according to the characteristics of different types of Jinyu air conditioning air pressure.

6. 所規劃的管道盡量取直，防止不必要的拐彎和分支管，以削減管道部分阻力

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

7. 從平面布置和經濟角度上考慮，能不必風管的當地就不必風管，必須運用風管的當地盡量把風管規劃短些

7. From the perspective of layout and economy, wind pipes are not necessary in places where air pipes are not needed, and local air pipes must be used to plan air pipes as short as possible.

8. 較長管道依據風量規劃成多段不同標準的風管，選用變徑管連接，變徑管的設置不宜過多，一般整根不超過四個，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. The connection of variable diameter pipes should be selected. The setting of variable diameter pipes should not be too much. Generally, the whole pipe should not exceed four. The length of variable diameter pipes should be determined by ">2(D-d)".

9. 送風管道與錦煜冷風機主機出風口連接處應密封好;室外管道過長宜規劃保溫，室內管道一般不須保溫

9. The connection between the air supply pipe and the outlet of the main engine of Jinyu air cooler should be well sealed; the outdoor pipe should be planned for insulation when it is too long, and the indoor pipe should not be insulated generally.

10. 若在規劃中存在支分管，則須在支管上裝設閥門或分風擋板以調節風量，使支管風量到達規劃值。

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.
