Title (EN) COOLING STORAGE CONTAINER IN PHASES
(FR) REFROIDISSEMENT D'UN RÉCIPIENT DE STOCKAGE EN PLUSIEURS PHASES
Abstract:
(EN) A storage container in a current temperature is cooled to a target temperature in two phases comprising a first phase of convective heat transfer from the storage container to dry ice, and a second phase of flowing sublimed dry ice to the storage container. Deviation of the current temperature from the target temperature is measured. The first phase is applied, when the deviation of the current temperature inside the storage container is higher than a threshold value for the deviation. The second phase is applied, when the deviation of current temperature inside the storage container is less than a threshold value.
(FR) Selon la présente invention, un récipient de stockage dans une température actuelle est refroidi à une température cible en deux phases comprenant une première phase de transfert de chaleur par convection du récipient de stockage en glace sèche, et une seconde phase d'écoulement de la glace sèche sublimée vers le récipient de stockage. L'écart de la température actuelle par rapport à la température cible est mesuré. La première phase est appliquée lorsque l'écart de la température actuelle à l'intérieur du récipient de stockage est supérieur à une valeur seuil pour cet écart. La seconde phase est appliquée lorsque l'écart de température actuelle à l'intérieur du récipient de stockage est inférieur à une valeur seuil.
