The study reported in this paper is concentrated on the estimation of the heat transfer from air to ice due to convection. Together with measurements of temperature and moisture profiles, air movements have been visualised in a small-scale model of a planned indoor ice rink. Some field tests concerning moisture content and temperature also have been realized in two different ice rinks. The study indicates that a low emissivity layer in the ceiling decreases the risk for ceiling condensation, decreases the heat radiation on the ice and decreases the driving force for air mixing. The convective heat exchange coefficient was estimated to 1.0 W/m2·°C by measuring the frosting rate on the ice. The warm, humid and contaminated air from the gallery streams next to the ceiling and mixes with the air over the rink.
