Abstract: A method of controlling a refrigerator is disclosed. The method 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: 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.

Abstract: Provided is an apparatus for sensing and removing dew on a refrigerator. The apparatus may include a heater disposed at a refrigerator body or inside a surface of a door, and a sensor disposed in close proximity to the heater. The sensor may be configured to sense dew formed on a prescribed surface at the refrigerator body or the door. The sensor may be disposed physically separate from the prescribed surface to sense formation of dew on the prescribed surface. The heater is controlled to generate heat that removes the sensed dew on the prescribed surface based on a signal from the sensor.
