Abstract
(DE)
Um eine Kältemittelverdichteranlage umfassend eine erste, expandiertes Kältemittel führende Kältemittelleitung, eine zweite, verdichtetes Kältemittel führende Kältemittelleitung, mindestens einen zwischen der ersten und zweiten Kältemittelleitung angeordneten Kältemittelverdichter, der durch einen Motor angetrieben ist, und eine Steuereinheit zum Betreiben der Kältemittel- verdichteranlage, die Betriebssicherheit einer derartigen Kältemittel- verdichteranlage zu verbessern wird vorgeschlagen, dass die Steuereinheit eine erste Zentralprozessoreinheit sowie mindestens eine mit der ersten Zentralprozessoreinheit kommunizierende Eingabe-/Ausgabeeinheit für Steuergrößen aufweist, und dass der ersten Zentralprozessoreinheit eine zweite Zentralprozessoreinheit zugeordnet ist, welche bei Ausfall der ersten Zentralprozessoreinheit die Steuerungsfunktionen zur Steuerung der Kälte- mittelverdichteranlage übernimmt.
(EN)
The problem addressed by the invention is that of improving the operating reliability of a refrigerant compressor system comprising a first refrigerant line that conducts expanded refrigerant, a second refrigerant line that conducts compressed refrigerant, at least one refrigerant compressor, which is arranged between the first and the second refrigerant lines and which is driven by a motor, and a control unit for operating the refrigerant compressor system. This problem is solved in that the control unit has a first central processor unit and at least one input/output unit for control variables that communicates with the first central processor unit, and that a second central processor unit is associated with the first central processor unit, which second central processor unit takes over the control functions for controlling the refrigerant compressor system if the first central processor unit fails.
(FR)
L’invention concerne un système de compresseurs de réfrigérant qui comprend une première conduite de réfrigérant qui conduit un réfrigérant détendu, une seconde conduite de réfrigérant qui conduit un réfrigérant comprimé, au moins un compresseur de réfrigérant qui est disposé entre le premier et la seconde conduite de réfrigérant et qui est entraîné par un moteur, et une unité de commande destinée à actionner le système de compresseurs de réfrigérant. Selon l’invention, pour améliorer la fiabilité de fonctionnement d'un tel système de compresseurs de réfrigérant, l'unité de commande comprend une première unité centrale de traitement et au moins une unité d'entrée/de sortie de variables de commande qui communique avec la première unité centrale de traitement, et la première unité centrale de traitement est associée à une seconde unité centrale de traitement qui prend en charge, en cas de défaillance de la première unité centrale de traitement, les fonctions de commande pour commander le système de compresseurs de réfrigérant.
