Abstract (en)
An object is to make it possible to perform refrigerant recovery in a rapid manner by using pump-down operation of outdoor units 4 even in the case in which a large amount of refrigerant that exceeds a storable amount of the outdoor unit 4 is charged in an air conditioner 2.An air conditioning system 1 includes: an air conditioner 2 including an indoor unit 5 and a plurality of outdoor units 4 connected to the indoor unit 5; and a control-device controller 30 that controls the air conditioner 2, and the control-device controller 30 alternately executes first control in which one of the outdoor units 4 is caused to execute pump-down operation and in which another one of the outdoor units 4 is put into a state where refrigerant is allowed to be recovered by a refrigerant recovery machine 6 and second control in which the outdoor unit 4 that executes the pump-down operation in the first control is put into a state where the refrigerant is allowed to be recovered by the refrigerant recovery machine 6 and in which the outdoor unit 4 that is put, in the first control, into the state where the refrigerant is allowed to be recovered is caused to execute pump-down operation.
