Abstract
A liquid cooling system for an outdoor ice forming surface provides a geothermal heat pump that has a refrigeration circuit with a compressor that is disposed between a cold tube section and a hot tube section. An outdoor structure has an upward facing ice forming surface that is configured to retain a body of ice, where a coolant line is provided at or near the ice forming surface. A fluid pump is coupled with the coolant line and is configured to circulate liquid through the coolant line and over the cold tube section of the geothermal heat pump to dispense heat before being recirculated to the ice forming surface of the outdoor structure.
