An ice surface is a cooling job with a deadline: the ice has to be ready for the first session and hold through the day. The plant that keeps it cold also produces heat, and a rink has places to put it.
The unit removes heat from the ice circuit. Suitable heat-recovery interfaces can supply the hall and hot-water preparation when temperatures and demand fit. The roof cooler stands idle in this mode.
Cold loops under the ice from a supply header to a return header, so the whole surface sits at the same temperature.
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.
The heat taken out of the ice is heat the hall, the dressing rooms and the snow-melt pit can use. When nobody needs it, the dry cooler takes it.
Retrofit of existing rink plants with one natural-refrigerant unit, connected to the headers you already have.
Illustrative system principle
Cold liquid from the supply header runs in loops along the track and back to the return header.
Chills the loops and lifts the heat to a useful temperature in the same machine.
The hall, the dressing rooms or the snow-melt pit; the dry cooler on the roof when nobody needs it.
Cold for the loops under the ice and heat for the hall, the dressing rooms and the snow-melt pit from one machine, delivered in a container with the dry cooler on the roof.
