Weak current College】 【composite insulating duct and duct comparison of iron sheet.

<br> With the rapid development of air conditioner industry, thus also contributed to the brisk wind pipe industry. From the original metal duct that nowadays all types of composite wind pipe, duct industry is constantly updated. In the past, often using metal duct ., but most fiberglass insulation, with a lot of carcinogenic substances, easy with condensed water, metal and easy rust, air tightness and technology complex, manufacturing processes, life is short, and so adverse factors have also been getting out of the market. < .br> Double-sided embossed foil composite insulating duct with non-toxic, insulation and corrosion-proof, durability, environmental protection energy conservation, acoustic noise, shock safe, leak-proof quality good, the installment convenient, the material quality of light, .no condensation, fast construction. Cost economy, and a series of advantages, its price in the current market occupies a considerable advantage. Lightweight composite wind pipes system from aluminum foil laminated insulation Panel duct, it consists of aluminum foil and thermal insulation Panel material combination ., the intermediate layer is nonflammable insulation, floor layer on layer respectively cover with aluminum foil. As a result of embossed foil composite insulation Board of main building materials is rigid foam duct material, so not only light, and heat insulation features more general galvanized ducts .. Tools and comprehensive as windpipe and by design, greatly speeding up the construction process. Simple and practical, attachments system technology ensures the integrity and relevance of the system. <br> Double-sided embossed foil composite insulating duct of superior performance basic performance in .several areas <br> 1. insulation <br> The wind pipes insulation effect is fine, 25 ¡ .æ, the thermal conductivity of only 0.0267W (m · K), or so (material) thermal resistance is greater than the equivalent thickness of traditional air duct, saving the cost of materials, greatly avoided because of the quality manual. Even so, .reduces energy loss runs, lowering the cost of running the air conditioning. <br> 2. gas-tight <br> Wind pipe forming, ensure that the adhesive is close, effectively ensure the wind pipe and at every point at the same temperature, .special connections guarantee system for superior tightness, close to the metal duct of 8 times. <br> 3. no particles, ensuring the physical and mental health <br> The wind pipes for double-sided foil structure, form a layer of particle barrier .barriers prevent dust in the wind pipe as an example of stream. The surface is smooth flow, 25m / s wind speed, tested did not find a dust particle shedding. The whole system-metallic structure, complete elimination of the drops of water, cold .bridge, hidden dangers, reduce the pipe wall of microbial growth and reproduction. <br> 4. Security fire performance <br> The current market the majority of air duct is reached, the national GB8624A solid not. Double-sided foil composite duct through .national nonflammable BI certification to meet the requirements of national fire codes. Can't say that it applies to all construction environment, but it is widely used in all business, commercial and domestic space, such as shopping malls, supermarkets, hotels, guesthouses, .as you release the extra worries. <br> 5. life <br> The design life of central air conditioner is 15-20 years, therefore ideal wind pipes system of life should be 15-20 years. Double-sided foil composite duct outer .insulation - composite foil with corrosion resistance, abrasion resistance, anti-aging, and other characteristics, make any necessary maintenance is simple and convenient. <br> 6. noise <br> The wind pipes structure ensures excellent acoustic insulation performance, fully absorb air .in all kinds of noise, vibration and echo, put an end to the ship by air duct, increased the variety of sound environment of comfort, giving the user a comfortable and quiet enjoyment. <br> 7. unparalleled competitive <br> Double- .sided foil composite duct installation convenient, produce and direct thermal insulation is a complete site workload small, takes only traditional metal duct of 1 / 5, high construction efficiency and significantly shortens the duration; and light weight, far lower than sheet metal duct and fiberglass .duct, easy handling and installation. Comprehensive cost more than traditional metal duct 30 per cent. But the wind tube in the factory floor to machinery production, and then transported to the site, site requirements, construction management more convenient. Ming installed beautiful, dark .dress can maximize the ceiling height on layer high enough space is especially important, greatly improved product competitiveness. It is expedient to air temperature is-40 ° c ~ + 80 ℃, pressure under the wind speed can reach 998Pa 25m / s, the excellent .performance makes double-sided foil series air duct in the wind pipe industry often share the step-by-step increase. <br>.
