ENERGY USAGE PREDICTION MODEL COMPARING OUTDOOR VS. INDOOR ICE RINKS

摘要

The overall aim of the project was to reduce energy usage in ice rinks with specific scope study to develop arncomparison tool for indoor and outdoor ice rinks based on an energy usage prediction model. Thernrefrigeration system, heat loads on ice surface and their correlation is studied in detail for an outdoor bandyrnice rink for season 2010-2011. The accurate estimation of heat loads on outdoor bandy rink with validatedrninput climate data and performance analysis of refrigeration system is being done. The cooling capacity andrnheat load on ice surface are calculated, compared and analysed considering energy usage affectingrnparameters and weather parameters like temperature, wind speed, relative humidity and solar load. Therndeviation between total cooling energy produced and total heat load energy is found 27% for season 2010-rn2011. The developed model provides a decision tool to choose between alternatives based on predictedrnenergy usage.
