Abstract
A refrigerator includes a first storage compartment, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to perform a first operation based on a first notch temperature for a first cooling operation, a second operation based on a second notch temperature for a heating operation, and a third operation based on a third notch temperature for a second cooling operation. The second notch temperature is higher than 0° C., and the third notch temperature is higher than the first notch temperature. Accordingly, it may be possible to efficiently supply the cold or heat until reaching a supercooling maintenance section.
