Thermal Response of the Concrete Slab of an Indoor Ice Rink (RP-1289).

The component-based simulation of the energy performance of refrigeration systems of an indoor ice rink requires mathematical models for several of the components including chillers, heat exchangers, the ice sheet cooling load, and the concrete slab. This paper presents two mathematical models of the thermal response of the concrete slab. Those models predict the brine temperature leaving the concrete slab and returning to the evaporator of the refrigeration system in terms of variables that can be measured in the refrigeration system: the brine temperature leaving the evaporator and entering in the ice-concrete slab and the ice temperature. Both models are calibrated and compared with measurements from an existing indoor ice rink located in Montreal. [ABSTRACT FROM AUTHOR]
