Abstract

There is provided a refrigerator capable of suppressing intra-compartment temperature from rising during a defrosting operation by means of a defrosting heater and capable of preventing temperature of foods from rising after the defrosting operation. The inventive refrigerator sets temperature for ending a freezing mode during a pre-cooling operation at pre-cooling freezing mode ending temperature which is lower than temperature during a normal operation by a predetermined temperature and conducts an alternate cooling operation until when the pre-cooling operation ends based on the pre-cooling freezing mode ending temperature.
