Types of composite air duct for central air conditioning

With the vigorous development of social economy, high-rise buildings are also increasing. Many office buildings are high-rise buildings. The ventilation pipes and central air-conditioning ducts of office buildings are the ventilation facilities of the whole floor and the main facilities of temperature control. The following is a brief introduction to several types of composite air ducts suitable for central air conditioning in office buildings.

1, inorganic glass magnesium composite air pipe; the material itself is double-sided inorganic glass fiber reinforced plastic polystyrene foam insulation board, made after the wind pipe no longer need to do heat treatment, coupled with high strength surface compound has an absolute advantage in wind resistance, so in the case of high-power fans, it is recommended to use glass magnesium composite air duct.

2. XPS type extruded composite air duct; XPS polystyrene composite insulation board composite double-sided aluminum foil, the weight of this material itself is quite light, and there is no impurities produced, but the fire resistance of this material is general, so it is used in ventilation facilities of small supermarkets and hotels more often, because the cost of extruded composite air duct is quite cheap.

3. Phenolic phenolic composite air duct made of phenolic aluminum foil and double sided aluminum foil. Phenolic foam is one of the most important insulation materials, so it has been widely applied in the central air-conditioning duct in recent years. Phenolic foam board is very light in weight, so it is suitable for building with heavy lifting capacity, but the phenolic board itself is easy to produce dust, so it is not suitable. It can be used in air duct with high air quality such as food.

4. Glass fiber type glass fiber composite air duct; glass fiber also known as centrifugal cotton, has strong antibacterial ability, has sterilization function, glass fiber board core has an important function is to have noise elimination and sound insulation function, so the composite glass fiber composite air duct is widely used in entertainment places, hotels, hospitals and other occasions, and is one of the most commonly used composite air duct in central air conditioning.
