Refrigeration apparatus

A refrigeration apparatus comprising:

• a refrigerant circuit including
• a heat source-side unit installed outdoors, and
• a utilization-side unit connected to the heat source-side unit,
• the refrigerant circuit being configured to perform a refrigeration cycle in which a high pressure reaches or exceeds a critical pressure of the refrigerant;
• and
• a control unit configured to control an action of the refrigerant circuit and to perform
• a first action of recovering at least a part of the refrigerant from the utilization-side unit and returning the refrigerant thus recovered to the heat source-side unit in a case where a stop condition of the utilization-side unit is satisfied, and
• a second action of prohibiting the first action in a case where a first condition indicating that a pressure at the heat source-side unit is equal to or more than the critical pressure of the refrigerant is satisfied, and
• the heat source-side unit includes a radiator and a refrigerant storage reservoir, and
• the control unit performs the second action in a case where a predetermined condition indicating that a pressure at the refrigerant storage reservoir is equal to or more than the critical pressure of the refrigerant is satisfied as the first condition.
