Title (EN) SUPERCOOLING SYSTEM
(FR) SYSTÈME DE SURFUSION
(KO) 과냉각 시스템
Abstract:
(EN) The present invention relates to a supercooling system which can supply heat to a stored object or generate heat according to a sensed temperature to maintain the stored object in a supercooled state. The supercooling system includes a cooling apparatus including a storing unit (S) storing a stored object, a cooling means cooling the storing unit, and a main control unit receiving external commercial power and controlling the cooling means to maintain the temperature in the storing unit (S) at a temperature below the maximum ice crystal formation zone, and a supercooling apparatus including an independent storage room (Sr) having a storing space therein to receive a storing container (Cr) containing a liquid to be supercooled and mounted and cooled in the storing unit (S), a temperature sensing unit (C1, C2) sensing the temperature of the independent storage room (Sr), a temperature control means mounted in the independent storage room (Sr) and controlling the internal temperature such that a temperature of an upper portion of the storing space or the storing container is higher than a temperature of the maximum ice crystal formation zone and a temperature of a lower portion of the storing space or the storing container (Cr), and a sub-control unit controlling the temperature control means based on the sensed temperature from the temperature sensing unit (C1, C2) to store the liquid in a supercooled state, maintaining the temperature control means in the off state when the temperature of the storing space or the storing container (Cr) is equal to or higher than a preset temperature-control start temperature, and controlling the temperature control means in the on and off states when the temperature of the storing space or the storing container is lower than a preset temperature-control start temperature.
(FR) La présente invention concerne un système de surfusion pouvant fournir de la chaleur à un objet stocké ou générer de la chaleur selon une température détectée afin de maintenir l'objet stocké dans un état de surfusion. Le système de surfusion comprend un appareil de refroidissement comportant une unité de stockage stockant un objet stocké, un moyen de refroidissement refroidissant l'unité de stockage, ainsi qu'une unité de commande principale reliée à une alimentation commerciale externe et commandant le moyen de refroidissement afin de maintenir la température dans l'unité de stockage inférieure à la zone de formation de cristaux de glace maximale. Le système de surfusion comprend également un appareil de surfusion comportant une chambre de stockage indépendante contenant un espace de stockage pour recevoir un récipient de stockage contenant un liquide à mettre à l'état de surfusion, qui est monté et refroidi dans l'unité de stockage, une unité de détection de température détectant la température de la chambre de stockage indépendante, un moyen de commande de la température monté dans la chambre de stockage indépendante et commandant la température interne de sorte qu'une température d'une partie supérieure de l'espace de stockage ou du récipient de stockage soit supérieure à une température de la zone de formation de cristaux de glace maximale et à une température d'une partie inférieure de l'espace de stockage ou du récipient de stockage. En outre, le système de surfusion comprend une unité de commande auxiliaire qui commande le moyen de commande de la température sur la base de la température détectée par l'unité de détection de température afin de stocker le liquide dans un état de surfusion, qui maintient le moyen de commande de la température à l'état désactivé lorsque la température de l'espace de stockage ou du récipient de stockage est égale ou supérieure à une température de démarrage de commande de la température prédéfinie, et qui commande le moyen de commande de la température dans les états activé et désactivé, lorsque la température de l'espace de stockage ou du récipient de stockage est inférieure à une température de démarrage de commande de la température prédéfinie.
(KO) 본 발명은 수납물의 과냉각 상태의 유지를 위해, 감지 온도에 대응하여 수납물에 열을 공급하거나 열이 발생되도록 하는 과냉각 시스템에 관한 것이다. 상기 과냉각 시스템은 수납물을 저장하는 저장고(S), 저장고를 냉각시키는 냉각수단과, 외부 상용전원을 인가받아, 저장고(S) 내의 온도를 최대빙결정 생성대 온도 이하로 유지하도록 냉각 수단을 제어하는 메인 제어부를 구비하는 냉각 장치와, 내부에 과냉각될 액체를 저장하는 수납용기(Cr)를 수납하는 수납공간을 구비하고, 저장고(S) 내에 장착되어 냉각되는 독립보관실(Sr)과, 독립보관실의 온도를 감지하는 온도 감지부(C1, C2)와, 독립보관실(Sr)에 장착되어 수납공간 또는 수납용기(Cr)의 상부의 온도를 최대빙결정 생성대 온도보다 높고, 수납공간 또는 수납용기(Cr)의 하부의 온도보다 높게 내부의 온도를 조절하는 온도 조절수단과, 온도 감지부(C1, C2)로부터의 감지 온도를 기준으로 하되, 수납공간 또는 수납용기(Cr)의 온도가 기설정된 온도조절 시작온도 이상인 경우, 온도 조절수단을 오프 상태로 유지하고, 수납공간 또는 수납용기(Cr)의 온도가 기설정된 온도조절 시작온도 미만인 경우, 온도 조절 수단의 온 및 오프 제어를 수행하여, 액체가 과냉각 상태로 보관되도록 하는 서브 제어부를 구비하는 과냉각 장치로 이루어진다.
