Future-ready refrigeration secures reliable operation at Ice rink
FACTS
End user: Karlskrona Kommun/Nobelhallen
Contractor: Kylmekano
Segment: Sport & Leisure – Ice rinks
Background: Comprehensive renovation of Nobelhallen, inaugurated in 1971, including the existing hall A, a new hall B, and an adjacent public swimming facility. The objective is to modernise the facility to meet today’s energy, safety and performance requirements while ensuring future-proof operation.
Products: SteelXL MT-only with 2 chillers, 2-step heat recovery and multiple suction groups
Specifications
- Replacing an aging refrigeration system for hall A and B ice rinks
-
Comfort cooling for facilities and the swimming area
-
Utilisation of recovered heat for space heating and the swimming facility
-
Low environmental impact using natural refrigerant
Challenges
-
- Replacing an aging refrigeration system within a limited installation window between hockey seasons
- Ensuring consistent ice quality under varying load conditions
- Reducing energy consumption and carbon footprint in a large, multi-use facility
- Integrating ice rink cooling, comfort cooling and heat recovery into one efficient system
Solution
Advansor’s CO₂-based refrigeration solution delivers reliable and energy-efficient cooling tailored to modern ice rink requirements.
Using multiple suction groups makes it possible for each group to operate at a pressure matched to its temperature load, so no load runs colder than necessary. This ensures better part-load regulation, lower energy costs and stable and precise temperature control per application.
Medium temperature (MT1): 700 kW at -16 °C
Medium temperature (MT2): 350 kW at 3 °C
IT suction group (IT): 0 kW at 10 °C
Results
Integrated heat recovery enables surplus heat from the refrigeration process to be reused for space heating and the adjacent swimming facility, improving overall energy efficiency.
Using the natural refrigerant CO₂, the system ensures stable ice conditions while significantly reducing environmental impact.
The result is a sustainable refrigeration system that helps Nobelhallen meet both current functional demands and long-term climate goals – demonstrating how CO₂ technology can future-proof ice arenas and sports facilities.
