Carbon Dioxide in Ice Rink Refrigeration

This scientific paper is to evaluate a new refrigerant application in ice rink refrigeration system under three different aspects; energy performance, heat recovery potential and economic efficiency. In order to make this evaluation, three main tasks are executed.

The average energy consumption of one ice rink is around 1000MWh/year, which approximately69% is occupied by the refrigeration unit and heating demand. With the aim of decreasing theenergy consumption, a new concept of refrigeration system with CO2 as a refrigerant has beendeveloped and it is promising to become a high potential next generation for refrigeration systemin ice rink.
