Title (EN) CASCADE REFRIGERATION SYSTEM
(FR) SYSTEME DE REFRIGERATION EN CASCADE
Abstract: front page image
(EN) The invention relates to a method for cooling a fluid or a body by means of at least a first vapour compression circuit (10) containing a first heat transfer fluid and at least a second vapour compression circuit (20) containing a second heat transfer fluid, the method comprising: - measuring the temperature of the external surroundings; and - setting the temperature of the second heat-transfer fluid to evaporation, according to the temperature of the external surroundings. The invention also relates to an installation suited to implementing this method.
(FR) L'invention concerne un procédé de refroidissement d'un fluide ou d'un corps au moyen d'au moins un premier circuit de compression de vapeur (10) contenant un premier fluide de transfert de chaleur et d'au moins un deuxième circuit de compression de vapeur (20) contenant un deuxième fluide de transfert de chaleur, le procédé comprenant: –la mesure de la température du milieu extérieur; et –l'ajustement de la température du deuxième fluide de transfert de chaleur à l'évaporation, en fonction de la température du milieu extérieur. L'invention concerne également une installation adaptée à la mise en œuvre de ce procédé.
