<p>A capacity shortfall in an indoor unit at a high load is prevented. An outdoor unit (10) includes at least three compressors (CM1, CM2, CM3) and has an oil equalization mode function for maintaining a proper oil level in each of the compressors (CM1, CM2, CM3). The outdoor unit (10) includes a controller (12) that controls starting and stopping of the compressors (CM1, CM2, CM3) in the oil equalization mode such that one of the compressors (CM1, CM2, CM3) at a time is stopped or operated at a low load while the other compressors (CM1, CM2, CM3) are operated.</p> |
