What Is an HVAC Duct?

South cloth air duct system is a kind of flexible air distribution system (Air Dispersion) made of special fibers. It is a unique air outlet mode that can uniformly supply air by relying on the unique air outlet mode of fiber penetration and nozzle jet. In China, the South system is often called cloth duct, bag duct, cloth duct, fiber cloth duct and so on.

In the world's frozen food industry in the 1960s and 1970s, in order to meet the special requirements of large cooling capacity and low wind speed in refrigerated areas, HVAC engineers in various countries tried to make air outlets made of ordinary cotton fiber fabrics, shaped like cloth bags (SOCKS). The same was true in China in the 1950s and 1960s, and many cases of cloth ducts were installed in the refrigeration industry. DURKEE INTERNATIONAL has been committed to the development of international new technologies and new products in the field of HVAC ... DURKEE INTERNATIONAL paid attention to the development prospects of global fiber fabric air distribution systems. Air ducts have brought a technological revolution to the field of Chinese wind systems. It has been widely used in commercial, public, stadium, industrial factory, food factory and other construction fields, and has quickly developed into a leader in the Asian market. Over the past few years, its international brand, Durkeesox, has developed rapidly around the world and has become a major supplier of international fiber fabric air distribution systems.

First, the surface air, large air volume, no sense of blowing. The South system adopts a unique surface air outlet mode in which the entire pipe wall fiber penetrates the air and microporous jets. The air outlet area is large, the air volume is large, the wind speed is low, there is no blowing feeling, and the comfort is excellent.

Second, the overall supply air is evenly distributed. The South system sends out air through the fiber gaps in the entire pipe wall or evenly distributed designed rows of small holes, and the air is distributed uniformly at each point to achieve a truly ideal overall uniform air supply.

Third, anti-condensation. The South system penetrates the cold air through the fiber of the entire pipe wall, and forms a cold air layer outside the pipe wall, so that there is almost no temperature difference between the inside and the outside of the pipe wall, which completely solves the problem of condensation and does not require pipe insulation.

Fourth, easy to clean and maintain, healthy and environmentally friendly. Because the South system is easy to disassemble and install, it can be easily wiped and cleaned to improve the cleanliness of indoor air and meet higher requirements for health and environmental protection.

Fifth, beautiful and high-end, diverse colors, outstanding individuality. A variety of colors can keep harmony with any environment style in the room, simple and upscale. At the same time, the system and color are completely personalized and customized.

6. Light weight, negligible roof load. The South system is made of special fibers and is extremely light. It is about 1/40 of the traditional metal wind system. It is especially suitable for places with no load-bearing capacity on the roof.

7. The system runs quietly and improves the quality of the environment (the Sox system has soft materials and low wind speed during operation, does not generate and transmit resonance, is quiet, and improves the quality of the environment).

Eight, simple installation, shorten the engineering cycle. The South system adopts a special supporting steel rope or aluminum rail suspension device system, which is simple and fast, and the installation time is often more than 1/10 of the traditional system, which greatly shortens the engineering cycle. Nine; flexible installation and reusable. The whole system is made of soft materials, and no trimming or calibration is required during installation. When in use, it will not be as easy to be scratched, pitted, and leaked as the metal pipe system, and the system suspension device is flexible to move, easy to install, and reusable. It is best in various places where temporary ventilation is required. select.

X. Comprehensive system cost savings and high cost performance. South's system design is simpler than the traditional air supply system, and replaces traditional air supply pipes, dampers, diffusers, tuyeres and other single components, accessories, and thermal insulation materials, single products, extremely light weight, easy transportation and installation, and comprehensive savings Total system cost. ^[1]
