Abstract: Disclosed is a refrigerator including a main body forming a refrigerating chamber and a freezing chamber each including a temperature sensor, a cooling unit having a compressor and an evaporator accommodated inside the main body and driven to circulate a refrigerant in the compressor and the evaporator to generate cold air around the evaporator, a fan positioned inside the main body to supply the cold air to the freezing chamber, a damper positioned between the freezing chamber and the refrigerating chamber and opened and closed to allow the freezing chamber and the refrigerating chamber to selectively communicate with each other, and a controller controlling the damper for a predetermined damper opening time when a temperature of the freezing chamber reaches a freezing satisfaction temperature according to driving of the cooling unit. A temperature change of the refrigerating chamber over time may be reduced and power consumption may be improved.
