PROBLEM TO BE SOLVED: To provide an air conditioner capable of suppressing an excess rise of discharge pressure in each of compressors and having high stability in protection control of the compressors.SOLUTION: An air conditioner includes: an interlocking control part for interlocking controlling compressors of respective outdoor units. An outdoor unit control part in each outdoor unit controls discharge pressure Ph of the compressor in the outdoor unit to preset upper limit discharge pressure Pmax or less by increasing/decreasing a rotational frequency of each outdoor fan until the rotational frequency of the outdoor fan becomes a maximum allowable value Rmax. After the rotational frequency of the outdoor fan of any one of a plurality of outdoor units reaches the maximum allowable value Rmax, the interlocking control part reduces capacity of the compressor in which the rotational frequency of the outdoor fan reaches the maximum allowable value Rmax and increases the capacity of the compressor of the outdoor unit in which the rotational frequency of the outdoor fan does not reach the maximum allowable value Rmax. |
