Development of methodology and programme for calculation of air parameters for air conditioning and ventilation of indoor skating rinks
Introduction. In premises with artificial ice, which include indoor ice rinks and ice arenas, in order to prevent ice softening, fog formation and condensate precipitation, the convective component of heat exchange should be spent on cooling the air of the ice field area to standardized values.
