Abstract: A method for controlling a refrigerator includes turning on a compressor to operate with a predetermined cooling power for cooling a storage compartment, turning off the compressor when a temperature of the storage compartment reaches a temperature equal to or lower than a first reference temperature, and turning on the compressor again when the temperature of the storage compartment reaches a temperature equal to or higher than a second reference temperature higher than the first reference temperature. In the turning on the compressor again, the compressor is operated with a cooling power determined based on an on slope, which is a temperature change slope of the storage compartment during an on time of the compressor, and an off slope, which is a temperature change slope of the storage compartment during an off time of the compressor.

Abstract: A control method for a refrigerator comprises: decreasing an output of at least one of a cold air supply means for a first storage chamber or stopping the cold air supply means, if a sensed temperature of the first storage chamber reaches a value less than or equal to a second reference temperature; increasing the output, if a certain time has passed after the temperature has reached the value less than or equal to the second reference temperature, or if the temperature reaches a first specific value between a first reference temperature and the second reference temperature; and decreasing the output or stopping the cold air supply means, if a certain time has passed after the output of the air supply means has been changed in a previous step, or if the temperature reaches a preset second specific value between the first specific value and the second reference temperature.

Abstract: A refrigerator includes a cabinet that forms a chamber, a partition wall configured to partition the chamber into a storage space and an air flow path, a partition shelf configured to partition the storage space into a first space and a second space, a heat exchanger provided in the air flow path, and a first damper provided in the air flow path to adjust air supplied to the first space.
