What are the advantages of hvac insulated duct board?
HVAC insulated duct board is currently widely used, among which rubber-plastic composite air ducts, phenolic, glass magnesium, etc. are the main representatives. It can completely replace the traditional air duct in the air-conditioning air delivery system. Let's take a look at the advantages of HVAC pipe insulation panels.
1. Good thermal insulation, which can greatly reduce the heat dissipation loss of the air conditioner
The thermal conductivity of the hvac insulated duct board is 0.016~0.036W/(m·k), while the thermal conductivity of galvanized steel duct and FRP duct is much larger. In addition, the unique connection method of the hvac insulated duct board ensures the excellent airtightness of the ventilation system, which is close to 8 times that of the galvanized steel duct. Data shows that when the same amount of heat (cold) is transported, the heat dissipation loss of the galvanized steel duct is 15%, the heat dissipation loss of the glass fiber reinforced plastic duct is 8%, and the heat dissipation loss of the phenolic foam insulation material duct is less than 2%.
2. Good silencing
The interlayer of the wall of the hvac insulated duct board is a porous phenolic foam material board that is interpenetrated with each other, which has good sound damping performance. In the central air-conditioning system, the noise generated by the air-conditioning unit during operation is in the range of 50-79dB, which is transmitted through the air supply duct to form indoor noise. The phenolic aluminum foil composite air duct itself is a very good tube muffler, and there is no need to set up muffler accessories such as muffler cover and muffler elbow.
3. Lightweight, can reduce construction load, and is easy to install
The weight of the hvac insulated duct board is light, about 1.4kg/㎡, while the bulk density of galvanized steel duct (0.8mm thick) and glass fiber reinforced plastic duct (3mm thick) are 7.08kg/㎡ and 15~20kg respectively /㎡, which can greatly reduce the load on the building and is extremely beneficial to the installation of the air duct. When installing, only need to set up a bracket every 4m or so to have enough supporting force. This greatly reduces the requirements for the bearing capacity of the brackets, hangers, etc., which makes transportation and installation very convenient.
