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.
