Title (EN) METHOD FOR REGULATING OF COOLING APPARATUS AND AN APPARATUS FOR APPLYING OF THE METHOD
(FR) PROCEDE DE REGULATION D'UN APPAREIL DE REFRIGERATION ET APPAREIL DE MISE EN APPLICATION DU PROCEDE
Abstract:
(EN) The invention relates to a method of controlling cooling aggregates in which two or more compressors (1, 2) are parallelly joined and in which the power output of said compressor is regulated by a control system according to the amount of output required. Additionally, the invention relates to the aggregate machinery necessary to execute the method. In accordance with the invention, the method requires that at least one compressor (2) be controlled by a frequency transformer in order to regulate the power output of the compressor in steps. In accordance with the invention, the aggregate includes at least one frequency transformer which is joined to at least one compressor (2) in order to regulate its power output without steps.
(FR) L'invention concerne un procédé de régulation d'ensembles de réfrigération dans lesquels au moins deux compresseurs (1, 2) sont reliés parallèlement et dans lesquels la sortie de puissance dudit compresseur est régulée par un système de commande selon le volume du débit requis. De plus, l'invention concerne le matériel relatif auxdits ensembles nécessaires à l'exécution du procédé. Selon l'invention, le procédé requiert qu'au moins un compresseur (2) soit commandé par un transformateur de fréquence afin de réguler la sortie de puissance du compresseur par étapes. Selon l'invention, l'ensemble comprend au moins un transformateur de fréquence relié à au moins un compresseur (2) afin de réguler sa sortie de puissance sans étapes.
