Ice rinks and skating ovals

The ice is held at the required temperature throughout the day. Heat removed from the ice can be used for the hall or other heating needs.

Typical duties

  1. Maintain the ice temperature

    A secondary coolant circulates through pipes under the ice, between supply and return headers.

  2. Outdoor and seasonal rinks

    A containerised unit with the dry cooler on the roof: delivered, connected to the headers and running, and moved or stopped when the season is over.

  3. Heat for the hall and changing rooms

    Heat removed from the ice can be used for the hall, changing rooms or the snow-melt pit. When it cannot be used, the dry cooler rejects it to outdoor air.

  4. Replace an older plant

    Retrofit of existing rink plants with one natural-refrigerant unit, connected to the headers you already have.

Technical details

CO₂ chiller and heat pump
One water-to-water CO₂ (R744) unit with optional ejector chills the loops under the ice and can supply recovered heat to the hall.
Components in the container
The container holds pumps and the unit, which has Alfa Laval plate heat exchangers and 304 stainless steel frame and piping.
PLC control and flow measurement
The containerised unit has PLC control, an HMI (operator screen) and integrated flow measurement; valve control and remote access are options.

How it works

Simplified system diagram

  1. Loops under the ice

    A secondary coolant flows from the supply header through pipes under the ice and back to the return header.

  2. CO₂ unit in the container

    Chills the loops and lifts the heat to a useful temperature in the same machine.

  3. Uses for recovered heat

    The hall, changing rooms or snow-melt pit. The roof-mounted dry cooler rejects heat when it cannot be used.

Cooling only
The ice is cooled and the heat is rejected through the dry cooler on the container roof.
Cooling with heat recovery
The system supplies recovered heat to the hall when the temperatures and heating demand match.
