PROBLEM TO BE SOLVED: To provide a compressor operation control device capable of reducing power consumption while dispensing with setting of a control pressure width and a reserve pressure width.SOLUTION: A compressor operation control device 10 controls starts and stops of a plurality of compressors 210, 211, 220, 230, 310, 320, 330, 331 on the basis of virtual capacities, by determining a prescribed one of invertor compressors 210, 211, 220, 230 as a reference compressor, and applying a ratio of a discharge air volume of each of the other compressors to a discharge air volume of the reference compressor, as the virtual capacity of the compressor, in controlling operations of the plurality of compressors 210, 211, 220, 230, 310, 320, 330, 331 in parallel operations of the plurality of invertor compressors 210, 211, 220, 230 and constant speed compressors 310, 320, 330, 331, which generate compressed air. |
