Beschreibung
Zusammenfassung:	A refrigeration system includes a plurality of utilization units provided for one air conditioning target space, a refrigerant leakage sensor that detects a leakage of the refrigerant in a lower part of the air conditioning target space, and a control unit. In a case where the refrigerant leakage sensor detects the refrigerant leakage, the control unit performs detection standby control on the utilization units such that the supply of the refrigerant to utilization-side heat exchangers is temporarily stopped. In a case where the refrigerant leakage is detected based on the state quantity of the refrigerant corresponding to the utilization units under the detection standby control, the control unit stops the use of the utilization unit in which the refrigerant leakage has been detected.
