Local Heating System to Improve Comfort of Spectators in the Stands of Indoor Ice Skating Rink

This paper discusses examples of the use of local heating systems that improve the comfort conditions of spectators, necessary for a full-fledged perception of events at an indoor ice rink. Indoor ice rinks are popular venues for sporting events, concerts and other entertainment events. However, spectators in the stands of indoor ice rinks during a hockey match or a performance of figure skaters often face the problem of low temperature, which, on the one hand, is necessary to maintain high ice quality, but on the other hand, can be uncomfortable with prolonged stay of the audience. The paper exa-mines the features of heat and mass transfer processes on indoor ice rinks, including convective and radiation heat exchange with the ice surface and the influence of the configuration of ventilation systems on the air environment inside the arena. The study on the need for mathematical modeling for a deeper understanding of the physical processes occurring inside indoor ice rinks. To study the operation of local heating systems, a numerical solution of a system of differential equations is used that describes the processes of heat and mass transfer in the air space of an indoor ice rink. The paper discusses several technical solutions for the organization of local heating systems. The advantages and disadvantages of the above technical solutions are highlighted. A comprehensive analysis of the operation of local heating systems at an indoor ice rink is an important contribution to the understanding the physical processes and parameters that affect the microclimate inside indoor ice rinks, and can also serve as the basis for optimizing such systems in order to ensure comfortable conditions for spectators.
