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.

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: A control method for a refrigerator includes sensing a temperature of a storage room; operating a cool air supply at a cooling power when the sensed temperature of the storage room is equal to or above a first reference temperature; operating the cool air supply at a delay power, which is less than the cooling power, when the sensed temperature of the storage room is equal to or below a second reference temperature, which is less than the first reference temperature while the cool air supply is operating at the cooling power; and adjusting the cooling power or the delay power of the cool air supply according to the temperature of the storage room while the cool air supply is operating at the delay power, and operating the cool air supply at the determined adjusted cooling power or delay power.
