Abstract
A refrigerator capable of supercooling a target object and a control method thereof are provided. The refrigerator includes a temperature sensor which senses a temperature of the target object in the cooling compartment, wherein the temperature sensor is prevented from being in contact with ambient cool air and is installed on a bottom surface on which the target object is placed so as to sense only the temperature of the target object. Further, the control method includes sensing a temperature of the target object at each interval of a specified time Δt, calculating a difference between two temperatures sensed at specified time intervals, and comparing the difference between two temperatures with a predetermined reference value ΔTc to determine the supercooled state of the target object.
