Project Summary

The underlying technology behind indoor ice rinks is the same technology at work in refrigerators and air conditioners. The main difference in an ice rink, other than sheer size, is that the refrigerant does not cool the ice directly. Instead, it cools brine, a calcium-chloride solution pumped through an intricate system of pipes underneath the ice. The brine’s chemical makeup keeps it from freezing. In most rinks, the pipes are embedded in a concrete or sand base. This field assessment demonstrates energy savings by treating ice rink water using the Realice water treatment system.
