Abstract: A method for controlling a refrigerator includes determining whether an ice bin accommodated in an ice making compartment that receives cold air from the first storage compartment is full of stored ice, determining, by a controller, whether an algorithm that prevents the ice stored in the ice bin from melting needs to be performed upon determining that the ice bin is full, and performing the algorithm.

Abstract: The present disclosure relates to a refrigerator. According to an embodiment of the present disclosure, the refrigerator comprises: an evaporator; a defrost heater; a temperature sensor to sense a temperature around the evaporator; and a controller to control the defrost heater. In response to reaching a defrost operation starting point, the controller is configured to perform a defrost operation mode, perform a continuous operation mode, in which the defrost heater continuously turns on, and a pulsed operation mode, in which the defrost heater switches between on and off, based on the defrost operation mode, wherein in response to performing the pulsed operation mode, the controller is configured to change the ON duration or power level of the defrost heater. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.

Abstract: A control method for a refrigerator comprises sensing a temperature of a first storage chamber; increasing an output of a first cooling fan if the temperature reaches a value greater than or equal to a second reference temperature; reducing the output of the first cooling fan if the temperature reaches a value less than or equal to a first reference temperature; increasing the output of the first cooling fan if a first reference time has passed after the temperature has reached the value or if the temperature chamber reaches a first setting temperature between the first reference temperature and the second reference temperature; and reducing the output of the first cooling fan if a second reference time has passed after the output of the first cooling fan has been changed, or if the temperature reaches a preset second setting temperature between the first setting temperature and the first reference temperature.

Abstract: In a refrigerator and control method thereof according to the present disclosure, when a load operation is terminated and a normal storage operation is performed, a re-input prevention control is performed to prevent the load operation from being performed even if an operation start condition of the load operation is satisfied. During the re-input prevention control, when a re-input prevention stop condition is satisfied, the re-input prevention control is controlled to be stopped. In this way, it is possible to prevent over-cooling of a first storage compartment, which may be caused by continuous input of the load operation, and respond smoothly to the corresponding load when a large load is input.

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: The present disclosure relates to a refrigerator. The refrigerator according to one embodiment of the present disclosure comprises: an evaporator; a defrosting heater; a temperature sensor; and a controller to control the defrosting heater. The controller is configured to: in response to a defrosting operation starting time arriving, perform a defrosting operation mode including a pre-defrosting cooling mode, a heater operation mode and a post-defrosting cooling mode; perform a continuous operation mode, in which the defrosting heater is continuously on; and when a temperature change rate sequentially increases, decreases and increases again, perform a pulse operation mode, in which the defrosting heater is repeatedly turned on and off. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.

Abstract: A method of controlling a refrigerator may include operating a first cooling cycle for a first storage compartment to drive a compressor and operating a first cooling fan for cooling the first storage compartment, and switching to a second cooling cycle for cooling a second storage compartment to drive the compressor and operating a second cooling fan for cooling the second storage compartment when a stop condition of the first cooling cycle is satisfied. The method may also include switching to a third cooling cycle for cooling the first storage compartment to drive the compressor and operating the first cooling fan when a stop condition of the second cooling cycle is satisfied.
