Abstract (en)
The purpose is to improve the security of a refrigeration apparatus including plural utilization units. A refrigeration apparatus (100) comprises: a refrigerant circuit (RC) that includes a heat source unit (10) which has a compressor (11), and plural utilization units (30), each of which has a utilization-side heat exchanger (32) and which are disposed in parallel to each other; plural on/off valves (36) that cut off a flow of supplied refrigerant in a closed state; and a controller (60) that controls the operation of the compressor (11) and each of the on/off valves (36) in accordance with a control mode. Each of the on/off valves (36) is disposed on a refrigerant inlet side of any of the utilization-side heat exchangers (32). The controller (60) is electrically connected to refrigerant leakage sensors (40) and, in a case where the refrigerant leakage sensors (40) have detected refrigerant leakage in any of the utilization units (30), transitions to a refrigerant leakage control mode, controls to the closed state the on/off valve (36) disposed on the inlet side of the utilization-side heat exchanger (32) of the refrigerant-leaking utilization unit (30), and causes the compressor (11) to operate at a predetermined rotational speed.
