Abstract

The present disclosure relates to a thermal storage unit 100 used for a refrigeration apparatus using CO₂ as refrigerant, including: a thermal storage 20 including a thermal storage material 21, particularly a phase changing material PCM, a thermal storage unit gas port 62 configured to communicate to a utilization-side heat exchanger 80A disposed outside the thermal storage unit 100, a first thermal storage unit fluid port 72 configured to communicate to the utilization-side heat exchanger 80A, a second thermal storage unit fluid port 32A configured to communicate to a heat-source-side heat exchanger 11, disposed outside the thermal storage unit 100, and a third thermal storage unit fluid port 52A configured to communicate to an expansion device 12 disposed outside the thermal storage unit 100, wherein the thermal storage unit 100 further includes: a first switching mechanism 31 communicating among the second thermal storage unit fluid port 32A, the third thermal storage fluid port 52A, the thermal storage unit gas port 62 and one side of the thermal storage 20, and a second switching mechanism 41 communicating among the first thermal storage unit fluid port 72, the third thermal storage unit fluid port 52A and the other side of the thermal storage 20. Moreover, the disclosure relates to a refrigerant circuit 1 for a refrigeration apparatus with a thermal storage, which is using CO₂ as refrigerant. Additionally, the disclosure relates to a heat exchange unit 200 that is particularly used for a refrigeration apparatus with a thermal storage, which uses CO₂ as refrigerant.
