Abstract
The present invention provides a refrigerator comprising: a cabinet provided with a storage compartment; a chamber provided with an evaporator for supplying cold air, a discharge duct through which the cold air having gone through a heat exchange by means of the evaporator is supplied to the storage compartment, and an introduction duct guiding the air in the storage compartment to the evaporator; a first temperature sensor for measuring the temperature of the evaporator; a second temperature sensor for measuring the temperature of the storage compartment; a third temperature sensor for measuring the temperature of the air supplied from the chamber to the storage compartment; and a control unit for determining the time for defrosting the evaporator on the basis of the temperatures measured by the first temperature sensor, the second temperature sensor and the third temperature sensor.
