Abstract
A refrigerator includes a control apparatus and a storing space composed of an upper space and a lower space between which the air or heat exchange is limited. The storing space has a liquid in a supercooled state. A determination unit calculates an accumulated time during which the temperature of the storing space is maintained in a supercooling temperature range below the maximum ice crystal formation zone of the stored liquid after the sensed temperature enters the supercooling temperature range, compares the accumulated time with a supercooled-state determination time and determines that the stored liquid is in the supercooled state if the accumulated time is equal to or greater than the supercooled-state determination time.
