LG’s popular Therma V range of air source heat pumps were specified at the Gosport Ice Rink in Hampshire.

Ice rinks have a cooling circuit that is below the ice in concrete or sand. This keeps the ice cold. Eventually this will freeze the ground below it and cause permafrost. This has the ability to move any structure in the immediate area and can cause major structural problems over time.

Providing heat below the insulation ensures this permafrost formation cannot take place. LG needed to provide heat below an existing ice rink by replacing the old supply and convert it to an ethylene glycol/water solution. This is a mixture that works well through an LG Therma V system.

Frost heave has always been a serious issue where ice pads are located on frost susceptible soils and operated all year round. Traditionally, heat recovery from refrigeration plant is used below ice rinks to provide a frost free sub base and prevent frost heave. Therma V’s inverter driven technologies maximise these operational efficiencies with ease of use.
