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.

Claims (10)

1. A CO2 refrigeration system comprising :
a CO2 circuit comprising a compression stage in which CO2 refrigerant is compressed to at least a supracompression state, a cooling stage in which 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 to maintain a pressure differential therebetween;
and a cooling circuit in which cycles a second refrigerant between a second side of the heat exchanger and an ice-playing surface, such that the second refrigerant absorbs heat from the ice-playing surface and releases heat to the CO2 refrigerant in the heat exchanger.
2. The CO2 refrigeration system according to claim 1, wherein the cooling stage comprises at least one of a gas-cooling unit, a heat-reclaim exchanger, and a heating unit.
3. The CO2 refrigeration system according to claim 2, comprising a plurality of the heating unit, with valves provided in relation to the plurality of heating unit to individually control an amount of CO2 refrigerant directed to each said heating unit.
4. The CO2 refrigeration system according to claim 3, wherein a fan of each said heating unit is controlled by a controller as a function of a temperature demand and of said amount of CO2 refrigerant.
5. The CO2 refrigeration system according to claim 1, further comprising at least one pump in the cooling circuit to induce a flow of the CO2 refrigerant therein.
6. The CO2 refrigeration system according to claim 1, further comprising a CO2 condensation reservoir between the heat exchanger and the compression stage.
7. The CO2 refrigeration system according to claim 1, further comprising a line extending directly from the heat exchanger to the compression stage.
8. The CO2 refrigeration system according to any one of claims 1 to 7, wherein the heat exchanger is a shell and tube type of heat exchanger, with the CO2 circuit side of the heat exchanger being the shell, the cooling side of the heat exchanger being the tubes.
9. The CO2 refrigeration system according to claim 1, wherein the cooling circuit comprises pipes under the ice-playing surface in which circulates the CO2 refrigerant to refrigerate the ice-playing surface.
10. The CO2 refrigeration system according to any one of claims 1-9, wherein the CO2 refrigerant in the CO2 circuit is compressed to a transcritical state.
