Abstract
The air distribution characteristics formed by fabric air dispersion system (FADS) are investigated by visualization experiment in a full-scale room. The airflow structure of FADS was presented and verified by this experiment, and compared with the traditional airflow patterns. The jet supply velocity and the outlet orientation are choosing as major factors influent on airflow field of FADS. A semi-empirical expression was given to calculate the jet deflection angle causing by different jet supply velocities. Meanwhile, the induction and flow junction phenomena are analyzed under different combination of outlet orientation, and the experimental results show that this induction is beneficial in design and application of FADS in practical engineering. The current experimental study and its results are helpful for using fabric air dispersion method in HVAC system.
