PROBLEM TO BE SOLVED: To provide a fluid compression system or a control device thereof, which can supply compressed fluid in response to a rapid change in the usage of the fluid even when the installation number of compressors is increased.SOLUTION: To solve the above problem, there is provided a fluid compression system comprising a plurality of compression devices for compressing fluid and a number control device for controlling the operation number of the plurality of compression devices. At least one among the plurality of compression devices is formed of a plurality of compressor bodies and is operated under capacity control of changing the operation number according to the usage of the compressed fluid or under fixed control of not changing output during operation irrespective of the usage of the compressed fluid. The number control device switches either of the capacity control operation and the fixed control operation to be performed by the plurality of compression devices.SELECTED DRAWING: Figure 1 【課題】 本発明は圧縮機の設置台数を増やした場合においても急激な流体の使用量の変化に対応して圧縮流体を供給できる流体圧縮システムまたはその制御装置を提供することを目的とする。【解決手段】 上記課題を解決するために、本発明は、流体を圧縮する複数台の圧縮装置と、複数台の前記圧縮装置の運転台数を制御する台数制御装置とを備え、複数台の前記圧縮装置のうち少なくとも１台は、複数台の圧縮機本体から構成され、圧縮流体の使用量に応じて運転台数を変更する容量制御運転または圧縮流体の使用量によらず運転時の出力を変更しない固定制御運転を行い、前記台数制御装置は、複数台の前記圧縮装置が容量制御運転または固定制御運転のいずれを行うかを切り替えることを特徴とする流体圧縮システムを提供する。【選択図】図１
