Performance Assessment of Air Conditioning Installation In Multifunctional Sports Hall Using Cfd Simulations

The purpose of the paper was testing of the air distribution system performance in the multifunctional hall. The numerical simulations of the airflows were made with the Ansys software. Three cases with two working modes of the installation were simulated: a large sport event with audience on the stalls, an exhibition with presentation boxes and an indoor ice rink. Direct results of the simulations and statistical data were analyzed. The results showed that for the ice rink and exhibition the system performance was very good, but during the large sport event with the full audience the air temperature in the occupied zone was much higher than the desired value.
