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: A refrigerator includes an evaporator, a defrost heater, a temperature sensor to detect a temperature associated with the evaporator, and controller to control the defrost heater. 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 a 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.

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.

Abstract: According to the present disclosure, after a load operation is performed by satisfying a start condition of the load operation, the load operation is terminated when a compartment temperature of a storage compartment satisfies a termination condition when a door is opened or when a temperature change in the storage compartment satisfies the termination condition. Accordingly, excessive power consumption during the load operation may be prevented, and thus power consumption may be improved.

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.

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 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.
