Ice rinks feature unique indoor environment and high energy consumption. Therefore, there is an urgent need to investigate the key challenges in the thermal environmental construction process and explore potential directions for optimization. This study conducts on-site measurement at six distinct ice rinks in Beijing to analyze the current environmental conditions and indoor heat and moisture flow in these facilities. In competitive ice rinks, zonal heat and moisture mixing from external warmer and more humid zones to the cold and dry ice field is pronounced, with the heat mixing ratio μh exceeding 66% and moisture mixing ratio μm exceeding 52%. Counteraction may occur between the ice refrigeration and the dehumidification air conditioning systems to simultaneously meet the control standards of the ice sheet and indoor air. The heating/cooling counteraction is common in traditional structured ice rinks, with the counteraction ratio exceeding 65%, while the humidification/dehumidification counteraction only occurs in a few cases. The negative impacts of mixing and counteraction amplify the system load, reaching up to 100.4 times the net demand value, significantly contributing to the high operational energy consumption. Targeted optimization measures are proposed to guide energy-efficient operations of ice rinks.
