Air ducts are a network of pipes used to transmit hot and cold air in an air conditioning system, and their design and layout are critical to ensuring the efficiency of an air conditioning system.
Air duct cleanliness requirements:
1. The inner surface of the superior air duct is smooth.
2. The galvanized layer of the air duct made of galvanized steel plate should not have surface area damage, falling off and other phenomena.
3. The material of bolts, nuts, washers and rivets used in the air pipe should be suitable for the performance of the pipe and should not produce electrochemical corrosion.
Air duct material:
Galvanized steel plate: The common material has good corrosion resistance and high strength. It is suitable for most environments, sometimes requiring additional insulation to prevent condensation and energy loss.
Composite materials: Usually contain an insulating material, such as phenolic foam, polyurethane, or glass wool, covered with foil or other protective layers. It has the characteristics of light, energy saving, fast installation and so on.
FRP: Corrosion resistant, suitable for chemical laboratory and other special environment. Its weight is light, but the cost is relatively high.
Stainless steel: Suitable for use in humid or corrosive environments.
Polyurethane material: Suitable for occasions where the environmental protection of the material is required.
Metal materials: In addition to the above galvanized sheet and stainless steel, it also includes other metal materials such as copper and aluminum, which are suitable for specific scenes.
Air duct installation and maintenance:
The installation of galvanized air ducts should based on the design drawings and site conditions. When installing air ducts, ensure that they are straight and not twisted. For open-mounted air ducts, there are strict allowable deviation values for levelness and verticality.
It is important to check the tightness and cleanliness of air ducts regularly, to avoid the performance degradation and loss of energy efficiency. It is necessary to diagnose and maintain the fault in time.
