Abstract

A device and a method for controlling a plurality of compressors (1-3) arranged for jointly producing a pressurized fluid, wherein each of the compressors comprises a valve (7-9), the position of the valve determining the size of the flow of the fluid and the compressor having at least three different states: a shut-off state in which the compressor has zero voltage and the valve is in a closed position, an unloaded state in which the compressor is under a voltage and the valve is in a closed position, and a loaded state in which the compressor is under a voltage and the valve is an at least partly open position. Information about each of the compressors regarding the power that the compressor consumes in the loaded and the unloaded states and which flow or flows that the compressor can deliver are stored. Information is received regarding the pressure of the fluid (P1-P4) and current valve positions for the compressors are received. The current need of fluid is estimated, based on the current valve positions of the compressors, the flow that the compressor can deliver and the pressure in the fluid. The valve positions of the compressors are adjusted with regard to the current need of fluid and the energy consumption of the compressors in a number of possible sets of valve positions, which meet the current need of fluid. <IMAGE>
