PROBLEM TO BE SOLVED: To provide a refrigeration system which properly performs cold storage and freezing by using one refrigeration machine without providing a compressor separately.SOLUTION: A refrigeration system includes a refrigeration machine unit 10 in which a cold storage compressor 11 and a freezing compressor 12 are connected in parallel to each other, a gas cooler 15 is connected to the discharge side of the cold storage compressor 11 and the freezing compressor 12, and a carbon dioxide refrigerant is enclosed therein. A cold storage cooler 31 is connected with an area between the high pressure side of the refrigeration machine unit 10 and a suction port of the cold storage compressor 11, and a freezing cooler 32 is connected with an area between the high pressure side of the refrigeration machine unit 10 and a suction port of the freezing compressor 12. |
