Fabric flexible ventilation duct

Project application of Buna fiber Fabric Air Duct in swimming pool of gymnasium

   With the rapid development of the construction industry, large-scale public buildings, such as cinemas, theaters, stadiums, exhibition halls, airport terminals and so on have been built. The gymnasium is one of the most typical tall space buildings. The use of fiber fabric air ducts in tall Spaces represented by gymnasiums has shown significant advantages. 
High height: usually the height of the theater and concert hall is 10-20 meters, the height of the ordinary gymnasium is between 10-30 meters, and the height of the atrium of the high-rise building can even reach 100 meters. If the traditional Air Duct is used, the installation is difficult and the risk factor is high. The weight of the fiber Fabric Duct is only 1/40 of the iron duct, and the air supply distance is up to 72 meters. 
   The ratio of exterior wall to floor area is large. The ratio of the outer wall and the ground of the standard floor of the office building is 0.2~0.3, and the ratio of the outer wall and the ground area of the large space building may reach 1, and the outside world has a greater impact on the natural convection of the indoor space, which is easy to cause cold air around the winter. The surface of the maintenance structure is prone to condensation, and it is necessary to take insulation measures for Windows and roofs. Indoor swimming pool, ice hockey hall should pay more attention to the condensation problem, the fiber fabric duct surface slowly permeates out of the air, the temperature inside and outside the pipe is the same, so the fiber fabric duct surface will not produce condensation phenomenon, and the penetration or jet flow mode is used to reduce the condensation phenomenon of the stadium wall and the glass surface. 
   Dense personnel, less ventilation. The volume of the ordinary gymnasium may be 10,000 to 20,000 square meters, the volume of the large gymnasium can reach 200,000 square meters, the upper space of the gymnasium is large, and the air distribution has higher requirements, and the use of fiber fabric air duct as the air distribution equipment at the end of the new gymnasium in China is the most ideal choice.
   Functional diversity. In addition to the function of sports facilities, the stadium building also has the functions of artistic performances, exhibitions, gatherings, etc., so it is often necessary to set up temporary stages and activity seats. This situation not only requires the stadium building to take into account the requirements of a variety of indoor air conditioning parameters, but also the presence of these devices also affects the setting of the stadium Air Conditioning System.
Therefore, the design of the ventilation system in the stadium should take into account a variety of functions, and the advantages of light weight, easy lifting and disassembly of the fiber fabric air duct can fully meet the needs of the diversity of air supply in the temporary places of the stadium.
