To provide a refrigerator that can reduce electricity costs charged for the amount of electricity consumed by performing defrosting, and to provide a defrosting control device and a defrosting control method.
The refrigerator 10a includes: a defrosting heater 8 that defrosts by heating; a defrosting-period predicted-value acquisition unit 24 that acquires a predicted value for the defrosting period, which represents the period in which defrosting is performed by means of the defrosting heater 8; an electricity-fee-information acquisition unit 25 that acquires electricity-fee information representing an electricity fee that changes over time; a defrosting time calculation unit 26 that computes a defrosting start time on the basis of the defrosting-period predicted value acquired by the defrosting-period predicted-value acquisition unit 24 and the electricity-fee information acquired by the electricity-fee-information acquisition unit 25 so that the electricity costs charged for the amount of electricity consumed by performing defrosting becomes no greater than a predetermined fee; and a defrosting control unit 28 that controls the defrosting heater 8 on the basis of the defrosting start time computed by the defrosting time calculation unit 26.
