Abstract
A refrigerator controls the temperature of an upper space and a lower space. A heat source supplier provides heat in the upper space. A control unit controls the heat source supplier based on the sensed temperature from a temperature sensor to maintain the temperature of the upper space to be higher than the temperature of the lower space, and control a cooling circuit to maintain the temperature of the lower space to be below the temperature of a maximum ice crystal formation zone of water and the temperature of the upper space to be over the temperature of the maximum ice crystal formation zone of water, thus maintaining a supercooled state of a stored liquid in the container as a preset state during a first time period.
