20100319368 | SUPERCOOLING RECOGNITION METHOD AND SUPERCOOLING APPARATUS - The present invention relates to a supercooling recognition method and a supercooling apparatus which can rapidly and precisely judge whether a stored object is maintained in a supercooled state on the basis of a temperature thereof. A supercooling recognition method according to the present invention includes the steps of: cooling a stored object to below a temperature of a maximum ice crystal formation zone thereof; and judging whether the stored object is maintained in a supercooled state on the basis of a temperature thereof during the cooling step. | 12-23-2010 |
20110264283 | REFRIGERATOR - The present invention relates to a refrigerator which can maintain and store a stored object in various states. The refrigerator includes a non-freezing apparatus having a storage room with a storing space composed of an upper space and a lower space, the air or heat exchange being limited between the upper space and the lower space, and a temperature control unit controlling the temperature of the upper space and the lower space. The non-freezing apparatus is installed in a storing space in which the cooling is performed and controls the temperature control unit to perform at least one of a process of maintaining a temperature-control start temperature region and a process of maintaining a supercooling temperature region which is lower than the temperature-control start temperature region, thus storing the storing space or the stored object in a state caused by the performed process. | 10-27-2011 |
20110302940 | REFRIGERATOR - The present invention relates to a refrigerator which can display a supercooled state or the proceeding degree of the supercooled state. The refrigerator includes a control apparatus which is formed in a storing space in which the cooling is performed, has a storing space composed of an upper space and a lower space between which the air or heat exchange is limited, stores a stored object in the storing space in a supercooled state, and controls the temperature of the upper space and the lower space, respectively. The refrigerator includes: a determination means determining the supercooled state of the stored object or the proceeding degree of the supercooled state; and a display means visually or aurally displaying the supercooled state or the proceeding degree of the supercooled state determined by the determination means. | 12-15-2011 |
20110302952 | COOLING APPARATUS - The present invention relates to a cooling apparatus including a non-freezing apparatus which can stably store a liquid in a container in a supercooled state by maintaining an upper space receiving an upper portion of the container at a higher temperature than a lower space receiving a lower portion of the container. A cooling apparatus includes a cooling space, a door opening and closing the cooling space, and a non-freezing apparatus installed in the cooling space or the door, an upper space thereof being maintained in a higher temperature region than a lower space thereof. The non-freezing apparatus of the cooling apparatus includes a separation film formed between the upper space of a high temperature and the lower space of a low temperature and limiting the heat exchange between the upper space and the lower space, thereby stably maintaining the liquid in the supercooled state. | 12-15-2011 |
20110303103 | COOLING APPARATUS - The present invention relates to a cooling apparatus with a passage therein to introduce the cool air from a cooling space into a non-freezing apparatus to cool a lower space of the non-freezing apparatus. A cooling apparatus includes a cooling space supplied with the cool air, a non-freezing apparatus installed in the cooling space and storing food in a non-frozen state, a cooling passage for introducing the cool air from the cooling space into the non-freezing apparatus, and a discharge passage for discharging the flow from the non-freezing apparatus to the cooling space. | 12-15-2011 |
20110308264 | REFRIGERATOR - The present invention relates to a refrigerator which can maintain a stored object in a desired state by controlling the temperature of an upper region and a lower region in the same storing space. The refrigerator includes a non-freezing apparatus having a storage room with a storing space composed of an upper space and a lower space, the air or heat exchange being limited between the upper space and the lower space, and a temperature control unit controlling the temperature of the upper space and the lower space. The non-freezing apparatus is installed in a storing space in which the cooling is performed and controls the temperature control unit to perform at least one of a process of rapid cooling at a temperature over the phase transition temperature, a process of entering a supercooling temperature region, and a process of maintaining the supercooling temperature region. | 12-22-2011 |
20120011861 | SUPERCOOLING APPARATUS - The present invention relates to a supercooling apparatus which can reduce a deviation of energy applied to a stored object. The supercooling apparatus includes a storage room provided in a storing unit where the cooling is performed and having a storing space therein to store or receive an object, a heat source supply unit installed in the storage room and supplying heat to the storing space or generating heat in the storing space; a temperature sensing unit sensing the temperature of the storing space or the stored object, and a control unit operating the heat source supply unit based on the temperature sensed by the temperature sensing unit to enable an upper portion of the storing space to have a temperature higher than a temperature of the maximum ice crystal formation zone, such that the storing space or the stored object is maintained in a supercooled state at a temperature below the maximum ice crystal formation zone, the control unit supplying or generating heat over a given magnitude during the supercooled-state control. | 01-19-2012 |
20120011880 | COOLING APPARATUS - The present invention relates to a cooling apparatus including a non-freezing apparatus which can be installed in a refrigerating chamber or a refrigerating chamber door and stably store food in a non-frozen state. A cooling apparatus includes a freezing chamber, a refrigerating chamber, a freezing chamber door, a refrigerating chamber door, and a non-freezing apparatus installed in the refrigerating chamber or the refrigerating chamber door and storing food in a non-frozen state. In the non-freezing apparatus, since a lower space is cooled by the cool air introduced from the freezing chamber and an upper space is cooled by the atmosphere of the refrigerating chamber, it is possible to reduce a heating value of a heater which is operated to maintain the temperature of the upper space to be higher than that of the lower space. | 01-19-2012 |
