"Lentpark" – ice skating and swimming stadium / Cologne, Germany

Implementation / Main components

Refrigerant

System start-up

2011

In 2011, KölnBäder GmbH completed the construction of an entirely new building on the grounds of the old ice skating and swimming stadium. Together with the swimming pool facility with indoor pool, outdoor pool and sauna, an ice rink was also constructed in combination with Europe's only elevated ice track.

Demands

The main requirement was for energy-efficient refrigeration. Both the elevated ice track and the ice rink were therefore designed as a direct evaporation system.

Solution

GfKK mbH installed a central refrigeration plant with reciprocating compressors. The waste heat is put to energy-efficient use for heating process water, melting the snow pits and antifreeze protection. The remaining waste heat is emitted to the outside with an air-cooled condenser that operates with EC ventilators.
