Abstract: A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.

Abstract: A control method for a refrigerator comprises: sensing a temperature of a first storage chamber; increasing an output of a first cooling fan if the temperature reaches a value greater than or equal to a second reference temperature; reducing the output of the first cooling fan if the temperature reaches a value less than or equal to a first reference temperature; increasing the output of the first cooling fan if a first reference time has passed after the temperature has reached the value or if the temperature reaches a first setting temperature between the first reference temperature and the second reference temperature; and reducing the output of the first cooling fan if a second reference time has passed after the output of the first cooling fan has been changed, or if the temperature reaches a preset second setting temperature between the first setting temperature and the first reference temperature.

Abstract: Provided are a refrigerator and a method for controlling the same. The refrigerator includes a cabinet defining a storage compartment, a door selectively opening or closing the storage compartment, a heater disposed in the cabinet or door to prevent dew from being formed on a surface of the cabinet or door, a refrigerator temperature sensor detecting a temperature of the storage compartment of the refrigerator, and a control unit adjusting an operation factor or output of the heater on the basis of a temperature value detected by the refrigerator temperature sensor.

Abstract: A refrigerator includes a compressor compressing a refrigerant, a condenser condensing the refrigerant compressed in the compressor, a refrigerant tube guiding a flow of the refrigerant condensed in the condenser, an expansion device decompressing the refrigerant condensed in the condenser, and an evaporator evaporating the refrigerant decompressed in the expansion device. The evaporator includes an evaporation tube through which the refrigerant decompressed in the expansion device flows, a coupling tube through a refrigerant heat-exchanged with the refrigerant of the evaporator flows, and a heat-exchange fin coupled to the evaporation tube and the coupling tube.
