A refrigerant circuit and an operation control means are provided. A refrigerant circuit is configured by the interconnection of a heat source unit, a plurality of utilization units, and expansion mechanisms. The heat source unit has a compressor and a heat source side heat exchanger. The utilization units have utilization side heat exchangers. The operation control means is capable of performing a refrigerant quantity judging operation to control constituent equipment such that a first state value becomes a first target control value. In addition, during the refrigerant quantity judging operation, the operation control means maintains a cooling capacity of a first utilization unit among the plurality of utilization units, which air conditions a predetermined space. |
