    摘要: To a refrigerant circuit of an air conditioner as a refrigerating apparatus, a plurality of outdoor units are connected. In an operation state where the first outdoor unit is operated with the second outdoor unit stopped, the air conditioner performs refrigerant collection operation for collecting and retaining surplus refrigerant to and in a second outdoor heat exchanger of the second outdoor unit. During the refrigerant collection operation, a second outdoor expansion valve is closed fully, and a second outdoor fan is operated. Part of refrigerant discharged from a first compressor flows into the second outdoor heat exchanger during the refrigerant collection operation. The refrigerant flowing in the second outdoor heat exchanger dissipates heat to outdoor air to be condensed. Since the second outdoor expansion valve is closed fully, the condensed refrigerant is retained in the second outdoor heat exchanger.
