The average energy usage of an ice rink is around 1000 MWh/year, of which approximately 70% goes to the refrigeration and heating systems. CO2 as refrigerant has favourable properties in this specific pplication due to its low-toxicity and high heat recovery potential. The use of CO2 refrigeration systems in the ice rink industry has potential to provide a paradigm shift moving from indirect systems to CO2 DX systems. This study evaluates the ice rink refrigeration system application where the overall energy performance including the heat recovery function is the main focus. A simulation model compares a conventional ice rink system with the CO2 DX alternative. The model is based on field measurements where real load profiles are generated. The results show that the CO2 DX system is the most efficient refrigeration system with the lowest total energy usage. Regarding the heat recovery function the CO2 DX system has a higher energy saving potential compared with conventional systems.
