The invention relates to a process for preventing condensation droplets from the ceiling or roof in skating rinks. The cause of these condensation droplets is that the ceiling/roof is cooled to below the dew point of the arena air as heat is radiated to the cold rink. The invention is now based on the fact that between the ceiling/roof and the rink there is hung a heat radiation shield, the bottom side and possibly also the top side of which has a very low emission coefficient, such as, for example, bright aluminium. The acquired effect is that both the actual ceiling/roof and the radiation shield assume the temperature of the arena air, which is higher than the dew point of the air, whereby condensation is prevented. Roughly the same effect is achieved by sticking the heat radiation shield directly to an existing ceiling. Apart from preventing condensation droplets, the heat radiation shield will reduce the energy consumed to cool the rink, owing to the lower radiation from the ceiling. In heated arenas, the heat consumption will also be reduced owing to the lower radiation from the ceiling to the rink.
