How do ice rinks stay frozen?
6 min read
Asked by: Kim Lewis
The most common method of refrigeration used in keeping an ice rink frozen is an indirect refrigeration system. This is where a liquid refrigerant (often ammonia) absorbs heat from a secondary liquid (often brine) which has absorbed heat from the source.
How does ice stay frozen on the ice rink?
In ice rinks, the refrigerant cools brine water, an anti-freezing agent, which goes through pipes underneath the ice. These steel pipes are typically embedded into a concrete slab and kept at 32 F / 0 C, so that any water placed on top of the slab freezes and becomes the skating surface that we see.
