Abstract
In defrosting operation, first individual defrosting operation wherein a first cooling heat exchanger (102) is defrosted, and second individual defrosting operation wherein a second cooling heat exchanger (112) is defrosted are alternately performed. While defrosting operation is performed, a refrigerant in one of the cooling heat exchangers (102, 112) not to be individually defrosted is discharged to the other one of the cooling heat exchangers (102, 112) to be defrosted.
