FabricAir received a request for an air distribution system that would stabilize the ice surface temperature at -8.5℃. In addition, it has to remove any humidity above the ice surface which would affect the quality of live broadcasting, as required by the Organizing Committee.
“It is a great honor to be trusted for such important works. Olympic games are the main and the most important sports event in the world and we are proud that FabricAir was chosen to create a tailored air distribution solution for a transformed arena. This proves the high quality of our product and engineering capabilities”, says Song He, Sales Manager at FabricAir China.
To keep the ice from melting from the higher temperatures coming from the spectators on either side of the rink, the heat needed to be separated by cool, dry air. However, the wind speed must be controlled below 0.5m/s. Excessive wind speed can affect the ice surface around the competition area. For this reason, FabricAir engineers designed a fabric ducting system with micro-perforations, through which air is sent into the cavity. The cavity length is 5.3m, and the air passes through the cavity and then goes out to the ground to form a barrier to insulate hot air. The initial velocity of the fabric duct is 0.35m/s, and the exit velocity of the ground cavity is 0.44m/s.
In addition, FabricAir prepared a CFD simulation for the customer in the early stage of the project. FabricAir CFD Service is the computational fluid dynamics program designed specifically for fabric ducting. Software program confirms a commercial ventilation design’s airflow patterns, temperature distribution, and velocities; or identifies potentially inaccurate performance issues before factory fabrication and site installation. The software also calculates the flow patterns, pressure loss, air velocity, temperature, and other invaluable parameters affecting a space’s ventilation design.
