Patent ID: 8640470

Claim:
In a refrigerator comprising a first storage compartment for storing an item, a second storage compartment for storing an item at a lower temperature than the first storage compartment, a cooling cycle including a compressor, a condenser for condensing a refrigerant from the compressor, a valve for directing the refrigerant from the condenser to first and second evaporators, with the first and second evaporators evaporating supplied refrigerants to cool the first and second storage compartments, respectively, and first and second fans for circulating cool air from the first and second evaporators, respectively, and a controller for controlling the first and second fans, the valve and the compressor, a control method of the refrigerator comprising: a first step of the controller activating the compressor if cooling of the second storage compartment is required and activating the second fan; and a second step of the controller deactivating the operation of the compressor, if the cooling of the second storage compartment is completed, and deactivating the operation of the second fan after the operation of the compressor is deactivated; wherein the second step includes the controller deactivating the operation of the second fan, if a temperature difference between the first evaporator and the second evaporator sensed by a sensing unit is below a predetermined level.
