A refrigeration apparatus includes: a heat source unit including a compressor for refrigerant and a heat-source-side heat exchanger; utilization units, each of which is connected in parallel to the heat source unit and includes a utilization-side heat exchanger; a refrigerant-flow-path switching unit that includes first gas-side control valves, each of which switches a flow of refrigerant in a corresponding one of the utilization units, and individually switches a flow of refrigerant in each of the utilization units; a first gas-side connection pipe disposed between the heat source unit and each of the first gas-side control valves and through which high-pressure gas refrigerant flows; first gas-side branch pipes, each of which is included in the first gas-side connection pipe and communicates with a corresponding one of the utilization units; and a blocking valve.
