Abstract
A system for creating rink ice and utilizing high-temperature heat generated when creating rink ice, the rink ice being created by spraying water over a base material layer and flowing cold brine through cooling tubes embedded in the base material layer includes: a heat pump performing a refrigerating cycle using CO2 as a refrigerant for producing cold brine and hot water, and a means for introducing the brine which has worked to freeze the water sprayed over the base material layer and received heat from the water sprayed over the base material layer and the ice created to the heat pump, thereby the hot water is produced by the heat pump by using heat contained in the brine introduced to the heat pump as a heat source and the brine deprived of the heat in the heat pump is returned to the cooling tubes to be used as the cold brine, thus the cold brine for creating the rink ice and cooling the ice layer created and the hot water to be used in ancillary facilities of the ice-skating rink facility are produced.
