Summary

The ventilation system in indoor ice skating arenas is usually planned for spectators. However, it was confirmed experimentally that players in arenas are much more sensitive to air contaminants than spectators in seats. In this paper, the air quality in an ice arena was measured. The air in the arena was polluted by the exhaust gas from ice surface smoother vehicles and it was stagnant due to the cold air stratification in the lower part of the arena. The ventilation system of the arena was modelled and the distributions of air and pollutant concentrations were simulated with Computational Fluid Dynamics (CFD). In CFD results, the cold stratification was reproduced and the concentration was found to be very high in the lower area. Several CFD case studies were conducted to develop an effective ventilation system. CFD simulation shows that the pollutant concentration in the arena can be reduced when the supply outlets and the exhaust inlet for ventilation system are designed appropriately.
