Abstract: A refrigerator may include a cabinet having a freezer compartment. An evaporator supplies cold air to the freezer compartment and an evaporator cover covers the evaporator. The evaporator cover has a supercooling passage for flowing some of cold air that has exchanged heat through the evaporator to a supercooling compartment of the freezer compartment. A cold air duct directs the other of the cold air that has exchanged heat through the evaporator to a top storage space over the supercooling compartment. A cold air guide device guides cold air in the cold air duct to a bottom storage space under the supercooling compartment.
