1. A method of controlling a refrigerator, the method comprising:
performing a preliminary operation, when the refrigerator is turned on or a defrosting operation is finished;
operating a cool air supply means with a predetermined output value during the preliminary operation;
determining whether a constant temperature control start condition is satisfied during the preliminary operation;
operating the cool air supply means with a predetermined output when it is determined that the constant temperature control start condition is satisfied;
a controller determining the output of the cool air supply means based on a difference between a current temperature of a storage compartment sensed by a temperature sensor and a previous temperature of the storage compartment while the cool air supply means operates with the predetermined output; and
the controller operating the cool air supply means with the determined output.
