Title:
SUPERCOOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/079946
Kind Code:
A2
Abstract:
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 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 at a temperature below the maximum ice crystal formation zone, and a supercooling apparatus including an independent storage room having a storing space therein to receive a storing container containing a liquid to be supercooled and mounted and cooled in the storing unit, a temperature sensing unit sensing the temperature of the independent storage room, a temperature control means mounted in the independent storage room 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, and a sub-control unit controlling the temperature control means based on the sensed temperature from the temperature sensing unit 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 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.
