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: The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure comprises: an evaporator; a defrost heater; a temperature sensor to sense ambient temperature around the evaporator; and a controller to control the defrost heater, wherein the controller is configured to: perform a defrost operation mode in a case of reaching a defrosting operation start time point; perform, based on the defrost operation mode, a continuous operation mode in which the defrost heater is continuously turned on, and a pulse operation mode in which the defrost heater is repeatedly turned on and off; and perform the continuous operation mode again after performing the pulse operation mode. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.
