Abstract
A refrigerator includes a refrigerating compartment temperature sensor, a cooling apparatus, in a state when driving time points of a refrigerating compartment and a freezing compartment are synchronized, to maintain an inside temperature of the refrigerating compartment by performing a cooling operation of the refrigerating compartment on the basis of a cut-off temperature of the refrigerating compartment that is varied by a difference between a temperature of the refrigerating compartment at a driving time point of the refrigerating compartment that is sensed by the refrigerating compartment temperature sensor and a cut-in temperature of the refrigerating compartment, and a control unit to control the driving of the cooling apparatus by varying the cut-off temperature of the cooling apparatus according to the difference between the temperature of the refrigerating compartment at the driving time point of the refrigerating compartment and the cut-in temperature of the refrigerating compartment.
