Method for adjusting a compressed air installation with several compressors, which mainly consists of two or more electrically driven compressors (2-3-4) of what is called the ~loaded/unloaded~ type and /or the turbo compressor (3) type and /or the compressor (4) type with variable rotational speed, whereby these compressors (2-3-4) are each connected to a single compressed air network (8) with their outlets (5-6-7), characterized in that the method makes use of a control box (28) which makes it possible to adjust the pressure (P) in the above-mentioned compressed air network (8) around a target pressure (PS) to be set, whereby the above-mentioned adjustment takes place by controlling the flow (Q) of one or several of the above-mentioned compressors (2-3-4), in particular in order to increase the overall flow supplied by the compressors (2-3-4) when the pressure drops too much, and in order to lower the overall supplied flow when the pressure becomes too high.
L'invention concerne un procédé de réglage d'une installation à air comprimé dotée de plusieurs compresseurs, qui consiste principalement en au moins deux compresseurs électriques (2-3-4)du type <= chargé/déchargé >= et/ou du type turbocompresseur (3) et/ou du type compresseur (4) à vitesse de rotation variable. Ces compresseurs (2-3-4) sont chacun connectés à un seul réseau d'air comprimé (8) par leurs sorties (5-6-7). Ledit procédé se caractérise en ce qu'il utilise une boîte de commande (28)permettant le réglage de la pression (P) dans le réseau d'air comprimé (8) susmentionné autour d'une pression cible (PS) à atteindre, par régulation du flux (Q) d'un ou plusieurs desdits compresseurs (2-3-4), en particulier pour augmenter le débit global fourni par les compresseurs (2-3-4) lorsque la pression chute trop, et afin d'abaisser le débit global lorsque la pression devient trop élevée.
