Abstract: A method of controlling a refrigerator is disclosed. The method includes: operating a cool air supply means with a predetermined output; a controller determining the output of the cool air supply means based on a current temperature of a storage compartment sensed by a temperature sensor while the cool air supply means operates with the predetermined output; and the controller operating the cool air supply means with the determined output. The controller determines that the output of the cool air supply means is decreased or increased when an absolute value of a difference between a previous temperature and a current temperature of the storage compartment is equal to or greater than a first reference value, and wherein the output of the cool air supply means is decreased or increased again when the absolute value of the difference between a current temperature of the storage compartment sensed again after a predetermined time has elapses and the previous temperature of the storage compartment is equal to or greater than the first reference value.

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 refrigerator control method of the present embodiment comprises the steps of: operating a compressor by operating a first cooling cycle for cooling a first storage chamber, and operating a first cold air supply means for the first storage chamber; and operating the compressor by switching into a second cooling cycle for cooling a second storage chamber, and operating a second cold air supply means, when a stop condition of the first cooling cycle is satisfied, wherein the cooling capacity of the compressor in the current second cooling cycle is determined on the basis of the representative temperature of the second storage chamber during one operating cycle which includes the previous first cooling cycle and the previous second cooling cycle, and a control unit performs control such that the compressor is operated in the current second cooling cycle with the determined cooling capacity.

Abstract: A refrigerator is disclosed. The refrigerator includes a cabinet including a storage compartment, a cool air supply means configured to operate to supply cool air to the storage compartment, a temperature sensor configured to sense a temperature of the storage compartment, and a controller configured to control an output of the cool air supply means based on a difference between a set temperature and a current temperature sensed by the temperature sensor and increase or decrease in temperature of the storage compartment sensed by the temperature sensor at a predetermined time interval.

Abstract: A refrigerator includes a control module which controls a first compressor, a second compressor, a first fan, a second fan, and a third fan, in which the control module performs a high-temperature initial simultaneous operation when the outside air temperature is at the outside air set temperature or more, performs a high-temperature initial alternation operation when the freezing compartment temperature is at the freezing compartment set temperature or less and the refrigerating compartment temperature is at the refrigerating compartment set temperature or less during the high-temperature initial simultaneous operation. The control module drives the first compressor and the second compressor together during the high-temperature initial simultaneous operation, and alternately drives the first compressor and the second compressor during the high-temperature initial alternation operation.
