Abstract

La présente invention concerne un dispositif de commande d'un ensemble de réfrigération muni d'un compresseur à aubes de pré-rotation réglables. Un compresseur centrifuge 20 est précédé d'aubes de pré-rotation réglables 31. Le moteur à vitesse variable 36 entraîne le compresseur. Le dispositif de commande régule la vitesse du moteur sur une partie de la courbe de variation de charge et régule la vitesse du moteur de façon associée à l'ouverture des aubes de pré-rotation sur une autre partie de la courbe de variation de charge pour assurer un état de fonctionnement avec une consommation d'énergie la plus faible possible, tout en évitant la mise en pompage. Ce trajet de commande optimal est réalisé en utilisant un signal qui est une mesure de la valeur du rapport entre pressions de sortie et d'aspiration du compresseur. Application à la climatisation des immeubles.The present invention relates to a device for controlling a refrigeration assembly provided with a compressor with adjustable pre-rotation vanes. A centrifugal compressor 20 is preceded by adjustable pre-rotation vanes 31. The variable speed motor 36 drives the compressor. The controller regulates the speed of the motor on one part of the load variation curve and regulates the speed of the motor in association with the opening of the pre-rotation vanes on another part of the load variation curve for ensure an operating state with the lowest possible energy consumption, while avoiding pumping. This optimal control path is achieved by using a signal which is a measure of the value of the ratio between the compressor outlet and suction pressures. Application to the air conditioning of buildings.
