(57) A refrigerator includes a refrigeration cycle system including a compressor, a condenser,
an expansion device, and an evaporator through which a refrigerant sequentially passes;
a blower fan sending air cooled by the evaporator to a freezer compartment and a refrigerator
compartment; and a damper regulating air sent from the evaporator to the refrigerator
compartment, in which when the freezer compartment temperature is not satisfactory
and the refrigerator compartment temperature is not satisfactory, the refrigerator
operates in a concurrent operation mode in which the compressor is operated, the damper
is opened, and first voltage is applied to the blower fan, and when the freezer compartment
temperature is not satisfactory and the refrigerator compartment temperature is satisfactory,
the refrigerator operates in a freezer compartment single operation mode in which
the compressor is operated, the damper is closed, and second voltage lower than the
first voltage is applied to the blower fan. Accordingly, it is possible to minimize
the power consumed in the freezer compartment single operation mode.
