LingHuaBu duct also called fabric duct is made of special fiber woven flexible air distribution system, mainly by fiber penetration and nozzle jet unique wind patterns, and that can send wind end of uniform air supply system. In the sixties and seventies of the frozen food industry, refrigeration area to meet the special requirements of large capacity, low wind speed, the HVAC engineer to try to ordinary cotton fabric made of air supply outlet, shaped like a bag (SOCKS). The same is true of the fifties and sixties in China, there are many cases of refrigeration industry cloth duct installation, hereinafter referred to as cloth duct. For more than 20 years, as the world fiber technology and spinning and weaving technology of continuous innovation, a growing number of the fibre is made into the air distribution system with special performance, make the fabric air distribution system to expanding application domain, has become a considerable share in the market of a ventilation system model. 
1, the comprehensive system of saving cost, cost-effective, &schwarz cloth duct system set duct, air valve, in a diffuser, insulation materials, and system design relative to conventional air supply system is simple, material consumption overall save system cost. In addition, due to its light weight (about 1/40) of traditional metal duct system weight and simple way of cleaning, the operation of the system maintenance cost is only 75% of the traditional metal pipes air supply system. 
2, comply with the fire code, safe and reliable all adlink bag duct system is using phosphorus is a permanent flame retardant fiber, the series of flame retardant fiber access to the national fire protection building materials inspection center flame retardant grade 1 certification (GB20286-2006, flame retardant grade 1 in the current fiber flame retardant grade, the highest level), its oxygen index is 38.3, 32, is superior to the technique index to continue burning and flame retardant time of 0 seconds, better than 5 seconds, the technical indexes of excellent fireproof performance. Additionally, the dimensional changes of its fracture, tear, bursting strength and physical properties such as wear resistance have been authority test fiber detection with international first-class comprehensive physical properties of the fiber material. 
3, superior overall performance air supply, uniform and comfortable adlink cloth duct system through the tube wall of fiber aperture or through a specially designed to sew, out of the wind hole to uniform air supply, effectively solve the sending, summer cold winter under hot air to air conditioning design problem, to ensure uniform distribution of indoor air. After testing, application summary cloth duct system can control indoor temperature difference in different regions of less than 1 ℃, perfect results overall uniform air supply. 
4, large area and high efficiency air supply, saving energy and reducing consumption throughout the adlink cloth duct system is a unified, all said air supply, ventilation system, different from traditional metal duct system through the way of flow unit distribution of cold and hot wind scattered, not only supply more even and comfortable, and air supply area is larger, supply more efficient, significantly reduce power consumption, conform to the requirements of the economic development of energy saving and consumption reducing. 
5, prevent condensation adlink cloth duct system through whole fiber permeability to air supply pipe wall, its special fiber properties and air distribution mode, make almost no difference in temperature inside and outside the wall, to ensure that thoroughly solve the problem of condensation, don't need to pipe insulation. 
6, flexible supply air, quiet and comfortable wind traditional metal materials of noise is a kind of refraction, running noise is bigger, the adlink cloth duct system adopts special soft and elastic fiber production, won't produce and resonance, and runtime wind speed is low, under normal operating conditions, noise lower than 20 db. 
7, light weight, low cost of transportation, installation, adlink cloth duct system of small volume, light weight, ultra-thin fiber, weighing about 1/70 of traditional metal duct), convenient transport, transportation cost is low. The cloth duct light weight, can greatly save installation labor and time. 
8, easy to install, save time adlink cloth duct system using wire rope hoisting or suspension of aluminum rail installation, each section duct connect with zipper, simple and easy to install, setup time is greatly reduced. In addition, because the system is very light quality, greatly reduces the bearing of roof and hoisting crane equipment requirements. 
9, easy to clean, healthy environmental protection adlink disassembling cloth duct system is very convenient, and its soft material use general can wash washing machine or hand washing, cleaning cost is very low. It allows users to regular cleaning, in order to maintain indoor air clean, more in line with HACCP, GMP and FDA process control of the high demand for clean, healthy and environmental protection. 
10, colour diversity, personalized prominent every adlink bag duct system is tailored for the customer design and production summary company, the modelling of system according to the requirements of the customers supply, combined with the actual situation (fan of parameters such as air flow, static pressure and the size of the supply air space, layout, etc.) design, color can be customized according to customers' requirement, the style is to keep harmony with the surrounding environment.
