<p>The present invention provides a method of controlling a refrigerator, including a main body having a plurality of storage chambers; a plurality of evaporators installed to independently cool the plurality of storage chambers, respectively; a refrigerant control valve for controlling refrigerant introduced into the plurality of evaporators; and a plurality of fans for circulating air of the storage chambers through the evaporators, respectively, the method includes a fan rotation step of, in an evaporator opening mode of the refrigerant control valve, rotating a fan of the plurality of fans, which circulates the air through an evaporator into which the refrigerant is introduced; an evaporator defrost step of, when a consecutive rotating time of the fan is greater than a setting time, operating the refrigerator in a defrost mode of the evaporator into which the refrigerant is introduced; and an evaporator defrost end step of, when a temperature sensed by a defrost sensor of the evaporator that is being defrosted is higher than a return setting temperature after the evaporator defrost step begins, finishing the defrost mode of the refrigerator. Accordingly, the present invention is advantageous in that it can defrost each evaporator efficiently at an exact point of time at which defrosting is required.</p> |
