Abstract: A refrigerator includes a cabinet configured to be formed with a first storage chamber and a second storage chamber, a first door configured to open and close the first storage chamber, a second door configured to open and close the second storage chamber, a first cooler and a heater configured to adjust the temperature of the first storage chamber, a second cooler configured to adjust a temperature of the second storage chamber, and a controller configured to perform a general operation of the first storage chamber in preference to door load response operation of the second storage chamber, of the general operation of adjusting the temperature of the first storage chamber and the door load response operation of the second storage chamber.

Abstract: A method for controlling a refrigerator includes turning on a compressor to operate with a predetermined cooling power for cooling a storage compartment, turning off the compressor when a temperature of the storage compartment reaches a temperature equal to or lower than a first reference temperature, and turning on the compressor again when the temperature of the storage compartment reaches a temperature equal to or higher than a second reference temperature higher than the first reference temperature. In the turning on the compressor again, the compressor is operated with a cooling power determined based on an on slope, which is a temperature change slope of the storage compartment during an on time of the compressor, and an off slope, which is a temperature change slope of the storage compartment during an off time of the compressor.

Abstract: In an under counter type refrigerator, when a defrosting period arrives, air of a storage compartment may be supplied towards an evaporator to perform a defrosting operation (natural defrosting operation) for removing frost generated on the evaporator, thereby improving defrosting efficiency and reducing power consumption.
