Abstract

A supercooling apparatus includes: a water container (106) for storing water at a low temperature by using chilled air provided thereto; a water supply passage (104a) having one end connected to a lower portion of the water container (106), for supplying water to the water container (106); a water withdrawal passage (104b) through which the water in the container (106) is withdrawn outside; and an electric field generating section positioned around the water container (106), for applying an electric field to the water container (106). Through this configuration, water in the container (106) does not undergo a phase transition even below the water phase transition temperature, but stays in a non-frozen liquid state. Since the water supply passage (104a) is connected to a lower portion of the container (106), the supercooled water kept inside container (106) does not freeze due to a shock from the fall of water being supplied to the container (106) from outside.
