Ice rinks combine a cold ice surface with relatively warm and humid air in the surrounding building. Under unfavourable conditions, moisture can condense in the cold air above the ice and form visible fog, reducing visibility and affecting the indoor climate.
FlowMotion analysed the air distribution, temperature and humidity conditions in an ice rink using CFD. The model included the ventilation system, the cold ice surface and the relevant heat and moisture sources in the hall.
The simulations showed how supplied air moved through the building and where cold, humid air could accumulate above the ice. By examining the local velocity and temperature fields, regions with a higher risk of condensation and fog formation could be identified.
Different ventilation concepts and operating conditions were then evaluated to improve air distribution while limiting the transport of moisture towards the coldest regions of the hall.
The CFD analysis provided a physical basis for improving the indoor climate and reducing the likelihood of fog above the ice.
