Abstract
A CO2 refrigeration system comprises a CO2 circuit. In a compression stage of the circuit, CO2 refrigerant is compressed to a supracompression state. In a cooling stage, the CO2 refrigerant from the compression stage releases heat. A pressure-regulating unit in a line extending from the cooling stage to one side of a heat exchanger maintains a pressure differential. A second refrigerant cycles in a cooling circuit between a second side of the heat exchanger and an ice-playing surface. The second refrigerant absorbs heat from the ice-playing surface and releases heat to the CO2 refrigerant in the heat exchanger.
