Abstract

Un système de refroidissement comprend une première boucle de refroidissement, une deuxième boucle de refroidissement et un échangeur de chaleur configuré pour transférer la chaleur de la première boucle de refroidissement à la deuxième boucle de refroidissement. La première boucle de refroidissement comprend une caractéristique de séparation vapeur/liquide configurée pour séparer la vapeur présente dans la première boucle de refroidissement en raison d’une fuite entre la première boucle de refroidissement et la deuxième boucle de refroidissement. La première boucle de refroidissement comprend également un capteur de pression configuré pour détecter une augmentation de pression dans la première boucle de refroidissement qui peut résulter d’une fuite du deuxième réfrigérant dans la première boucle de refroidissement.
