What are the classifications of air conditioning ducts?

* * * Plate flange air duct

* * * Plate flange air duct, also known as flangeless air duct, is faster, more convenient and has less air leakage than traditional rectangular air duct. Its advantages are saving materials, reducing engineering investment, small air leakage, reducing energy consumption and saving operating costs. * * * Automatic production line of plate flange air duct. The stainless steel and galvanized air duct produced by this production line can be directly pressed by splicing or angle steel, or the air duct and flange can be integrally formed.

Angle steel air conditioning pipeline

Angle steel air conditioning duct, also known as angle iron air conditioning duct, is the earliest form of duct connection, which is to weld long strips of steel perpendicular to each other on both sides and embed them into the duct with rivets.

Materials: iron air duct, composite air duct, FRP air duct. Among them, the composite air duct has the most varieties, which are divided into aluminum foil, color steel, glass magnesium and so on according to the outer layer veneer material; According to the interlayer (insulation layer) materials, there are polyurethane, phenolic resin, extrusion, glass fiber and polystyrene. In this way, a variety of air ducts are formed by different veneer materials and different interlayer combinations. For example, aluminum foil phenolic duct, color steel phenolic duct.

This needs to be determined according to the characteristics of various air ducts. Or adopt aluminum foil composite air duct, which is generally light and beautiful in appearance, and is more suitable for steel structure buildings with poor bearing capacity and some projects without suspended ceiling, such as supermarkets. .
