Abstract: An apparatus for controlling a refrigerator, and a method for diagnosing a fault of the refrigerator are presented. More specifically, a power consumption of a refrigerator may be measured, and a fault of a plurality of loads included in the refrigerator may be diagnosed based on the measured power consumption. Accordingly, all of the plurality of loads included in the refrigerator may be diagnosed whether they have a fault or not. Further, among the plurality of loads included in the refrigerator, one or more loads having feedback uncontrollable may be diagnosed whether they have a fault of not.

Abstract: A refrigerator and a method for controlling a refrigerator, including a plurality of compressors and a plurality of evaporators disposed on inlet-sides of the plurality of compressors to supply cool air to a refrigerating compartment and a freezing compartment includes determining whether a temperature of the refrigerating compartment belongs to a refrigerating compartment satisfaction range, determining an indoor temperature when the temperature of the refrigerating compartment does not belong to the refrigerating compartment satisfaction range, and determining whether a load corresponding operation condition is satisfied when the determined indoor temperature belongs to a set range. When the load corresponding operation condition is satisfied, a simultaneous operation of the refrigerating compartment and the freezing compartment is performed, and when the load corresponding operation condition is not satisfied, a cooling operation of the refrigerating compartment is performed.

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.
