A supercooling system includes a cooling apparatus and a supercooling apparatus. The cooling apparatus includes a storing unit storing an object, a cooling unit, and a main control unit controlling the cooling unit to maintain the temperature in the storing unit at a temperature below the maximum ice crystal formation zone of the liquid. The supercooling apparatus includes an independent storage room having a storing space, a temperature sensing unit sensing the temperature of the independent storage room, a temperature control unit mounted in the independent storage room and controlling the internal temperature and a sub-control unit controlling the temperature control unit based on the sensed temperature from the temperature sensing unit to store the liquid in a supercooled state.
