Cloth 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, referred to as "cloth duct or 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. 
 
 
 
LingHuaBu duct characteristics is introduced: 
 
 
 
1, the comprehensive system of saving cost, cost-effective 
 
 
 
LingHuaBu duct system set duct, air valve, in a diffuser, insulation materials, and the system design is relatively traditional 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, in line with the fire code, safe and reliable 
 
 
 
All LingHuaBu 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, technical indexes of better than 5 seconds, it has 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 
 
 
 
LingHuaBu duct system through walls or fiber aperture by specially designed to sew, the wind hole outward uniform air supply, and effectively solves the sending, summer cold winter warm air under the air conditioning design problems, to ensure uniform distribution of indoor air. Tested, different areas can be used cloth duct system within 1 ℃ indoor temperature control, to achieve the ideal effect of uniform air supply whole. 
 
 
 
4, high-efficient air large area, saving energy and reducing consumption 
 
 
 
The whole LingHuaBu 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 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 
 
 
 
LingHuaBu 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 
 
 
 
Traditional metal duct material to noise is a kind of refraction, running noise is bigger, but LingHuaBu duct system made of soft flexible special fibers does not produce resonance and transmission, and runtime wind speed is low, under normal operating conditions, noise lower than 20 db. 
 
 
 
7, light weight, low cost transportation and installation 
 
 
 
LingHuaBu 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 
 
 
 
LingHuaBu 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 
 
 
 
Disassembling LingHuaBu 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, individuation 
 
 
 
Every LingHuaBu duct system is tailored for the customer design and production 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.
