Abstract: A method of controlling a refrigerator includes starting a first cooling cycle to cool a first storage compartment by operating a compressor and a first fan, determining whether a start condition of a second cooling cycle to cool a second storage compartment is satisfied, operating a second fan for the second storage compartment when the start condition of the second cooling cycle is satisfied, determining whether an output change condition of the second fan is satisfied while the second fan operates, and changing a speed of the second fan when the output change condition of the second fan is satisfied.

Abstract: A refrigerator of the present embodiment comprises: a cabinet having a storage compartment; a cooling means which operates to cool the storage compartment; a temperature sensor for sensing a temperature of the storage space at a set time interval; and a controller for controlling the cooling means, wherein the controller adjusts an output of the cooling means on the basis of at least one of a first factor which is a difference value between a previous temperature of the storage compartment and a current temperature of the storage compartment and a second factor which is a difference value between a predetermined set temperature and a current temperature of the storage compartment, and adjusts the set time interval on the basis of at least one of the first factor and the second factor.
