Question:
The refrigeration system for an indoor ice rink is to be sized by an HVAC contractor. The refrigeration system has a COP (coefficient of performance) of 0.5. The ice surface is estimated to be ??2?C and the ambient air is 24?C. Determine the size of the refrigeration system in kW required for a 110 m diameter circular ice surface.GIVENRound ice rinkDiameter (D) = 110 mIce surface temperature (Ts) = ?? 2?CAir temperature (T??) = 24?CCOP of refrigeration system = 0.5ASSUMPTIONSAir is quiescentThe effects of sublimation are negligibleRadiation heat transfer isnegligible
