Traditional air supply pipes for central air conditioners usually have an inner layer made of iron sheet or fiberglass reinforced plastic, wrapped with thermal insulation material, and wrapped with aluminum foil at the outside, which makes the air supply pipes heavy in weight, time-consuming in construction and installation, poor in appearance, low air tightness, and high energy consumption. Compared with traditional air ducts, phenolic composite air ducts have the following advantages:
1. Good thermal insulation, which can greatly reduce the heat loss of air conditioners.
2. Good noise elimination.
3. Light weight, which can reduce the building load and facilitate installation.
4. Durable and long service life.
5. Reduce the floor height.
6. It can shorten the construction period.
7. Sanitation.
8. Beautiful, suitable for surface decoration.
9. Wide application range.
The surface of the phenolic aluminum foil composite air duct is sealed with aluminum foil, thus ensuring the hygiene of the conveying medium, avoiding secondary pollution, and the inner layer is free of condensed water and rust. In traditional air ducts, glass wool and asbestos are prone to moisture absorption, leading to severe deterioration in thermal insulation performance after absorbing water. Moreover, asbestos is a carcinogen, and glass wool dust can stimulate the skin and make construction personnel itch all over. In addition, galvanized steel duct is prone to rust and cold bridge phenomenon.
8. Beautiful and suitable for surface decoration
Phenolic aluminum foil composite air duct can be made into various colors, beautiful, especially suitable for surface decoration. The surface of traditional air ducts requires on-site aluminum foil wrapping, so the surface installation effect is not very good.
The thermal conductivity of the phenolic composite air duct is 0.016~0.036W/(m · k), while the thermal conductivity of the galvanized steel plate air duct and the glass fiber reinforced plastic air duct is much larger. In addition, the unique connection method of phenolic composite air duct ensures excellent air tightness of the ventilation system, close to 8 times that of galvanized steel duct. Some data show that when conveying the same heat (cold) amount, the heat loss of galvanized steel duct is 15%, that of glass fiber reinforced plastic duct is 8%, and that of phenolic foam insulation material duct is less than 2%.
