A brand new sports complex is being built in Leiden on Sportboulevard De Vliet. The complex comprises an indoor swimming pool measuring 25 × 35 meters and an ice skating center with a frozen oval for ice hockey and short track, complemented by a beginner's, curling, and 250-meter skating rink.
The challenge for Nijssen was to design a sustainable NH₃ and CO₂ system that could supply both cooling and heating to the swimming pool and ice rink, while simultaneously meeting the high demands of athletes and visitors.
Under the leadership of main contractor De Vries en Verburg, Nijssen supplied an NH₃ and CO₂ cooling and heating system, including the cold distribution system. The installation serves both the ice hockey rink and short track oval, as well as the curling and recreational rinks and the swimming pool.
By combining natural refrigerants with a cleverly designed heat pump concept, the system achieves low energy consumption. The Nijssen Control System ensures integrated control, monitoring, and logging of the entire installation, guaranteeing comfort and energy efficiency.
As a Leiden-based company, Nijssen is proud to contribute to this gem of a construction project for the Municipality of Leiden.
Combined Cooling and Heating Supply
The uniqueness of this project lies in the integration of cooling and heating within a single system. By utilizing NH₃ and CO₂ as natural refrigerants, the system can optimally cool ice rinks and efficiently heat the swimming pool. Heat recovery and heat pump technology ensure a minimal ecological footprint.
Thanks to Nijssen's combined cooling and heating system, we have a future-proof sports complex where comfort and sustainability converge.
