Furthermore, once the cold storage material 45 has been cooled, the cooling medium introduced into the space 35 to cool the cold storage material 45 can be used as is, and the cold storage device 1 can be used immediately. Therefore, an extremely easy-to-use cold storage device 1 can be provided.

Abstract

L'invention concerne un dispositif de stockage à conservation du froid qui utilise un matériau retenant le froid, dans lequel la variation de température dans un récipient à conservation du froid est supprimée, un effet de conservation du froid élevé peut être obtenu pour un article à refroidir, et permettant de refroidir efficacement le matériau retenant le froid. Dans un dispositif de stockage à conservation du froid 1, un espace 35 est formé par un fond 32 et des parois latérales 31a-31d entourant une partie de stockage à conservation du froid 33 d'un récipient à conservation du froid 30, et un matériau retenant le froid 45 est disposé dans l'espace 35. Dans l'espace 35, un fluide frigoporteur est introduit à partir d'une partie d'introduction de fluide frigoporteur 36, et est évacué par une partie d'évacuation de fluide frigoporteur 38. Le matériau retenant le froid 45 est refroidi par le fluide frigoporteur s'écoulant dans l'espace 35. Après que le matériau retenant le froid 45 a été refroidi, la partie d'introduction de fluide frigoporteur 36 et la partie d'évacuation de fluide frigoporteur 38 sont respectivement fermées par des vannes d'ouverture/fermeture 36A et 38A, et le fluide frigoporteur est maintenu dans l'espace 35. Un article à refroidir situé à l'intérieur de la partie de stockage à conservation du froid 33 est maintenu à froid au moyen du matériau retenant le froid 45 et du fluide frigoporteur remplissant l'espace 35.
