FLUID COMPRESSION SYSTEM AND CONTROL DEVICE THEREFOR

摘要

An object of the present invention is to provide a fluid compression system which can supply compressed fluid in accordance with a sudden change in an amount of fluid used even when the number of compressors to be installed is increased, and a control device thereof. In order to solve the problem, provided is a fluid compression system, including: a plurality of compression devices which compress fluid; and a number of device controller which controls the number of operating compression devices of the plurality of compression devices, in which at least one of the plurality of compression devices is configured of a plurality of compressor main bodies, and performs a volume control operation which changes the number of operating compression devices in accordance with an amount of compressed fluid used, or a fixed control operation which does not change an output during the operation regardless of the amount of the compressed fluid used, and the number of device controller switches a state where the plurality of compression devices perform the volume control operation and a state where the compression devices perform the fixed control operation.
