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: A refrigerator and a method of controlling an operation thereof are proposed. In the refrigerator and method thereof, heat control of heaters for preventing a damper from freezing is performed according to at least any one condition set in consideration of a room temperature and refrigerator internal humidity. Accordingly, consumption of power due to unnecessary heat generation of the heaters may be reduced, thereby improving the power consumption.
