Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2018/033968
Kind Code:
A1
Abstract:
A refrigerator comprises: an insulated box that has a storage space therein, with the space partitioned into a plurality of storage chambers by a partitioning member; a low temperature chamber that is provided as one of the storage chambers and that stores, without freezing, an object to be refrigerated at a temperature below the freezing point; a cooling device that cools the storage space; and a control device that repeats, by controlling the cooling device, a first process in which the interior temperature of the low temperature chamber is lowered from a second temperature that is higher than the freezing point of the object to be refrigerated to a first temperature that is lower than the freezing point during a predetermined time period, and a second process in which the temperature is increased from the first temperature to the second temperature and the second temperature is maintained for a predetermined amount of time. The control device controls so that the time integral value of the difference between the freezing point and the interior temperature of the low temperature chamber when the interior temperature of the low temperature chamber is lower than the freezing point balances with the time integral value of the difference between the freezing point and the interior temperature of the low temperature chamber when the interior temperature of the low temperature chamber is higher than the freezing point.
