Abstract: A method of controlling a refrigerator that includes: operating a cool air supply means with a predetermined output; a controller determining the output of the cool air supply means based on a current temperature of a storage compartment sensed by a temperature sensor while the cool air supply means operates with the predetermined output; and the controller operating the cool air supply means with the determined output. The controller determines that the output of the cool air supply means is decreased or increased when an absolute value of a difference between a previous temperature and a current temperature of the storage compartment is equal to or greater than a first reference value, and wherein the output of the cool air supply means is decreased or increased again when the absolute value of the difference between a current temperature of the storage compartment sensed again after a predetermined time has elapses and the previous temperature of the storage compartment is equal to or greater than the first reference value.

Abstract: A method for controlling a refrigerator comprises: as a first refrigeration cycle for refrigeration of a first storage chamber is operated, operating a compressor and operating a first cold air supply; when the first refrigeration cycle has been operated for a first run time, converting to a second refrigeration cycle for refrigeration of a second storage chamber, and operating a second cold air supply; and if the second refrigeration cycle has been operated for a second run time, stopping the second refrigeration cycle. A first reference time is determined using a representative value obtained based on the temperature of the first storage chamber during a single run cycle, which includes a previous first refrigeration cycle and a previous second refrigeration cycle. A second reference time period is determined using a representative value obtained on the basis of the temperature of the second storage chamber during the single run cycle.

Abstract: The method for controlling the refrigerator includes operating a first cooling cycle for cooling the first storage compartment to operate the compressor and operating a first fan for the first storage compartment, and switching the first cooling cycle to a second cooling cycle for cooling the second storage compartment to operate the compressor and operating a second fan when a stop condition of the first cooling cycle is satisfied. A temperature of each storage compartment is sensed at sampling time intervals in each cooling cycle. Further, a cooling power of the compressor is determined for each sampling time based on a sensed current temperature of the storage compartment, and the compressor is operated at the determined cooling power.
