The invention relates to a method of controlling a fluid compression system, said compression system comprising at least one compression means (1) for compressing a fluid medium, means for taking said compressed medium to a point of demand (9) and at least one means for conditioning said fluid medium prior to the point of demand (9). According to the method, the permissible minimum (P3min) and maximum (P3max) values of the user line pressure (P3) at the point of demand (9) are defined, the user line pressure (P3) is continuously monitored with the help of a pressure sensor (16), the working pressure (P2) of said compression means is monitored, the pressure difference between the working pressure (P2) of said compression means (1) and the user line pressure (P3) at the point of demand (9) is monitored, the pressure rate-of-change of the fluid medium delivered to the point of demand (9) is monitored, and at least one of the compression means (1) is controlled with the help of a control unit (12) on the basis of at least one of the monitored parameters defined in the foregoing steps of the method.
Technique de commande d'un système de compression de fluides comprenant au moins un dispositif compresseur (1) servant à comprimer un milieu fluide, un dispositif servant à amener ledit milieu fluide comprimé en un point déterminé (9) et au moins un dispositif de conditionnement dudit milieu fluide avant le point déterminé (9). Les valeurs minimale (P¿3min?) et maximale (P¿3max?) admissibles de la pression de fluide fixée par l'utilisateur (P¿3?) au point déterminé (9) sont définies, la pression de fluide fixée par l'utilisateur (P¿3?) est constamment contrôlée par un capteur de pression (16), la pression de régime (P¿2?) du dispositif compresseur (1) est contrôlée, la différence de pression entre la pression de régime (P¿2?) du dispositif compresseur (1) et la pression de fluide fixée par l'utilisateur (P¿3?) au point déterminé (9) est contrôlée, le taux de variation de la pression du fluide amené au point déterminé (9) est contrôlé et l'un au moins des dispositifs compresseurs est commandé par un module de commande (12) en fonction d'un au moins des paramètres contrôlés indiqués ci-dessus.
