Title (EN) LOW TEMPERATURE STORAGE CABINET
(FR) MEUBLE DE RANGEMENT A BASSE TEMPERATURE
Abstract:
(EN) A low temperature storage cabinet whose freezing compartment maintained at an ultra-low temperature by a binary refrigerating apparatus is improved in thermal insulation effect. A vertical ultra-low temperature freezer (1) is constituted of an insulating case of a composite configuration formed of vacuum insulating panels and foamed insulating material, an insulating door of a composite configuration formed of a vacuum insulating panel and foamed insulating material, and the binary refrigerating apparatus for refrigerating articles stored within the insulating case. The binary refrigerating apparatus generates ultra-low temperature by cascading a high temperature side refrigerant circuit and a low temperature side refrigerant circuit.
(FR) Cette invention se rapporte à un meuble de rangement à basse température dont le compartiment de congélation, maintenu à une température ultra-basse par un appareil de réfrigération en deux parties, possède des caractéristiques d'isolation thermique améliorée. Un compartiment congélateur (1) vertical à ultra-basse température est constitué d'un logement isolant de structure composite formée de panneaux à vide isolant et d'un matériau expansé isolant, d'une porte isolante de structure composite formée d'un panneau à vide isolant et d'un matériau expansé isolant, et de l'appareil de réfrigération en deux parties conçu pour réfrigérer des articles stockés à l'intérieur du logement isolant. Ledit appareil de réfrigération en deux parties génère une température ultra-basse au moyen d'une liaison en cascade d'un circuit réfrigérant du côté haute température et un circuit réfrigérant du côté basse température.
