[Problem] To provide an air conditioner device which carries out defrosting operation control in accordance with the capacities of the indoor expansion valves, thereby preventing damage to the compressor, and delayed return to heating operation. [Solution] An outdoor equipment controller (200) has a defrosting operation condition table (300a) which defines startup rotation speeds (Cr) in accordance with a flow coefficient sum (Cva) representing the sum of flow coefficients (Cv) which indicate the capacities of indoor expansion valves (52a-52c). The outdoor equipment controller (200) adds the flow coefficients (Cv) of the indoor expansion valves (52a-52c) which have been input by an installation information input unit (250) and calculates the flow coefficient sum (Cva), and referring to the defrosting operation condition table (300a), decides upon a startup rotation speed (Cr). When initiating a defrosting operation, the outdoor equipment controller (200) starts up the compressor (21) at the decided startup rotation speed (Cr), and for a predetermined time (one minute) after initiating the defrosting operation, maintains this startup rotation speed (Cr) and drives the compressor (21). |
