A refrigerator equipped with storage compartments in which objects to be cooled are housed, a cooling device that supplies cold air to the interior of the storage compartments, and a control device that controls the cooling device, and repeatedly executes a first step in which, during a first period of time, the temperature in the storage compartments is lowered to a first temperature which is lower than the freezing point of the objects to be cooled, and a second step in which, during a second period of time, the temperature in the storage compartments is raised to a second temperature which is higher than the freezing point of the objects to be cooled. Furthermore, the time-integrated value of the difference between the freezing point and the temperature in the storage compartments while the temperature in the storage compartments is lower than the freezing point of the objects to be cooled is identical to the time-integrated value of the difference between the temperature in the storage compartments and the freezing point while the temperature in the storage compartments is higher than the freezing point of the objects to be cooled. |
