Document Type and Number:
Japanese Patent JP2022083236
Kind Code:
A
Abstract:
To suppress an influence of change of a refrigerant state in excess/deficiency determination of the refrigerant amount in a refrigerating device.SOLUTION: A heat source unit (10) is connected to utilization units (60, 70) and includes a compression element (20) for compressing a refrigerant, and a control portion (101). The control portion (101) performs a first operation for delivering a refrigerant to the utilization units (60, 70) by operating the compression element (20), and a second operation for determining a refrigerant amount by circulating the refrigerant in the heat source unit (10) by operating the compression element (20) while stopping the circulation of the refrigerant in the utilization units (60, 70), after termination of the first operation.SELECTED DRAWING: Figure 8
