Abstract

A supercooling apparatus includes a refrigeration area into which chilled air produced by a refrigeration cycle with a refrigerant flow is introduced: a non-freezing chamber (200) positioned inside the refrigerator area, for storing food in a non-frozen supercooled state; and electrodes (230) for applying an electric field to the non-freezing chamber. With this type of configuration, foods can be stored in a non-frozen state for an extended period of time.
