Abstract: The present disclosure relates to a refrigerator. The refrigerator includes an evaporator, a defrost heater, a temperature sensor to detect an ambient temperature of the evaporator, and controller to control the defrost heater, wherein, in response to a defrosting operation start time point arriving, the controller is configured to perform a defrost operation mode including a pre-defrost cooling mode, a heater operation mode, and post-defrost cooling mode, perform a pulse operation mode in which the defrost heater is repeatedly turned on and off based on the heater operation mode, and change a magnitude of cooling power supplied in the post-defrost cooling mode based on an ON period of the defrost heater or a temperature of a cooling compartment in the pulse operation mode. Accordingly, defrosting efficiency and power consumption may be improved, and cooling power after defrosting may be efficiently supplied.

Abstract: A method for controlling a refrigerator comprises: as a first refrigeration cycle for refrigeration of a first storage chamber is operated, operating a compressor and operating a first cold air supply; when the first refrigeration cycle has been operated for a first run time, converting to a second refrigeration cycle for refrigeration of a second storage chamber, and operating a second cold air supply; and if the second refrigeration cycle has been operated for a second run time, stopping the second refrigeration cycle. A first reference time is determined using a representative value obtained based on the temperature of the first storage chamber during a single run cycle, which includes a previous first refrigeration cycle and a previous second refrigeration cycle. A second reference time period is determined using a representative value obtained on the basis of the temperature of the second storage chamber during the single run cycle.

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 may include a cabinet having a freezer compartment. An evaporator supplies cold air to the freezer compartment and an evaporator cover covers the evaporator. The evaporator cover has a supercooling passage for flowing some of cold air that has exchanged heat through the evaporator to a supercooling compartment of the freezer compartment. A cold air duct directs the other of the cold air that has exchanged heat through the evaporator to a top storage space over the supercooling compartment. A cold air guide device guides cold air in the cold air duct to a bottom storage space under the supercooling compartment.
