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: A method of controlling a refrigerator includes: controlling a cooling unit such that an output of the cooling unit becomes a first reference output for a first reference time previously determined; controlling the cooling unit such that the output of the cooling unit becomes a second reference output for a second reference time previously determined; calculating a representative value of a temperature of a storage compartment for an operating period, which is made by a sum of the first reference time and the second reference time, and comparing the calculated representative value with a specific temperature in a temperature satisfying range of the storage compartment; and varying, by a control unit, at least one of the first reference time and the second reference time depending on a comparison result between the specific temperature and the representative value and controlling operating of the cooling unit based on a varied reference time.

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 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.
