Research on improving thermal and humidity conditions in a ventilated ice rink arena using a validated CFD model

Numerical simulations of physical phenomena associated with the flow of air, heat and moisture occurring in an actual ventilated ice rink were prepared by means of Ansys CFX 14.5 based on a previously validated numerical model. The validated model was supplemented with an air humidity ratio comparison. Additionally, people (skaters and spectators) were modelled. Different methods of dehumidifying and distributing the air were considered for this building. The aim of this study was to investigate the influence of different factors on improvement of indoor thermal and humidity conditions due to the presence of people and maintenance of good technical condition of the facility. The simulation results were compared with direct calculation results, the surface division method, statistical analysis and the TOPSIS method.
