Abstract: Ice surfaces dictate energy usage in skating rinks because they are the largest heat exchangers in the building. This study aimed to improve the concrete material used in ice rinks to maximize the performance of their refrigeration systems. The Hot Disk TPS 2500 S measured the thermal conductivity and thermal diffusivity of the improved concrete using the Transient Plane Source (TPS) method. Results indicated that adding iron ore to the concrete might improve the thermal conductivity of the cooling system by more than 50%, making it more efficient.
