PIR HVAC Ductwork is an outstanding air conditioning and ventilation duct system.
characteristics and advantages of PIR HVAC Ductwork
PIR air ducts are much lighter than traditional galvanized iron sheet air ducts. For instance, in the air conditioning system of a large shopping mall in Xi 'an, the total area of the air ducts is 14,000 square meters. The weight of the galvanized iron sheet and glass wool insulated air ducts is 188 tons, while that of the PIR energy-saving insulated air ducts is only 16 tons. This reduces the labor intensity and the load on buildings, which is very important for high-rise buildings and light steel structure factories.
The core material of the PIR air duct is PIR foam plastic, and the surface of the air duct is embovered anti-rust aluminum foil. The average noise reduction can reach 3dB/m, and the noise at the air outlet is less than or equal to 47dB. It can eliminate the machine noise and aerodynamic noise of the air conditioning system without the need to install additional silencers and silencing elbows.
Core advantage of PIR HVAC Ductwork
Low resistance:
PIR air ducts use embossed anti-rust aluminum foil and other materials as the air duct surface. The aerodynamic obtuse Angle linear flow type relief design has a buoyancy effect on the air, greatly reducing the frictional resistance of the transmitted air. There is almost no dust sedimentation, and the frictional resistance is less than that of traditional galvanized iron sheet air ducts.
Fire-resistant and safe:
PIR air ducts have excellent flame-retardant performance. When burning, a carbonized layer forms on the surface of the foam, preventing the spread of flames and not generating harmful gases. They meet relevant Fire protection standards, such as reaching the domestic B1 standard (GB 8624-2006).
