Numerical Simulation Flow and Temperature Fields of Fiber Air Dispersion System

摘要

Fiber air dispersion system (FADS) is an advanced flexible ventilation terminal in ventilated areas. Its benefits are numerous, which are air diffusion without feeling, anti-condensation, easy cleaning and low cost etc. The technology of computational fluid dynamics (CFD) was used in this paper. At first, a physical model of the environment conditioned by FADS was built. Then, the both field of temperature and flow in the environment was simulated. The boundary conditions and parameters was measured and calculated. Finally, the numerical results were verified by comparing with the experiment data to confirm the reliability of the model. Meanwhile, by using the indoor air evaluation standard, FADS was confirmed to provide a more comfortable environment and better air quality.
