Refrigeration apparatus

A refrigeration apparatus, comprising:

• a refrigerant circuit including a heat-source-side circuit provided with a compressor and a heat-source-side heat exchanger, and an utilization-side circuit provided with an utilization-side heat exchanger,
• the refrigeration apparatus being capable of executing a cooling operation of performing a refrigeration cycle in the refrigerant circuit with the heat-source-side heat exchanger serving as a radiator and the utilization-side heat exchanger serving as an evaporator, wherein
• the heat-source-side circuit includes
• a liquid side control valve provided for a liquid side pipe in which a refrigerant flows from the heat-source-side heat exchanger toward the utilization-side heat exchanger in the cooling operation,
• a liquid side bypass pipe that allows a portion of the liquid side pipe between the heat-source-side heat exchanger and the liquid side control valve to communicate with a suction side of the compressor, and
• a liquid side bypass valve provided for the liquid side bypass pipe,
• the refrigeration apparatus further comprises a controller configured to execute, upon receiving a leakage signal indicating a leakage of the refrigerant from the utilization-side circuit, a refrigerant recovery control operation of actuating the compressor with the liquid side control valve closed so that the refrigerant in the utilization-side circuit is recovered in the heat-source-side circuit, and
• the controller is configured to execute a valve control operation of opening the liquid side bypass valve in the refrigerant recovery control operation.
