Abstract: A refrigerator includes a controller wherein the controller detects opening and closing of a door during a normal temperature control in which a compartment temperature of a first storage compartment is maintained at a normal set temperature, to supply cold air to the first storage compartment for a first time period, in a case where the controller detects, via a temperature detection unit within the first time period, a temperature rise range equal to or more than a temperature rise range set in advance, cause the compartment temperature to shift to a first set temperature lower than the normal set temperature for a second time period and, thereafter, cause the compartment temperature to shift to a second set temperature higher than the normal set temperature for a third time period and then cause the compartment temperature to shift to the first set temperature for a fourth time period.

Abstract: A storage compartment, operation display means configured to display a plurality of power saving levels each indicating a power saving index and to accept an operation input of selecting one power saving level from among the plurality of power saving levels, and control means configured to, when an operation input of selecting one power saving level from among the plurality of power saving levels displayed on the operation display means is made, calculate one or a plurality of power saving plans regarding a target temperature for the storage compartment in accordance with the selected one power saving level, are included. The operation display means displays the power saving plans calculated by the control means and accepts an operation input of executing the power saving plan.
