A refrigerator, comprising: a compressor configured to compress and circulate a refrigerant; a cooler configured to generate cold air; a first storage compartment having an internal temperature maintained within a first temperature range; a second storage compartment having an internal temperature maintained within a second temperature range different from the first temperature range; a first cold air passage configured to guide the cold air generated in the cooler to the first storage compartment; a second cold air passage configured to guide the cold air generated in the cooler to the second storage compartment; a partition configured to separate the first cold air passage from the second cold air passage, wherein the first cold air passage is partially defined by a first surface of the partition, the second cold air passage is partially defined by a second surface of the partition, and the first surface is opposite to the second surface on the partition; and a damper comprising: a first opening configured to communicate with the first cold air passage, a second opening configured to communicate with the second cold air passage, characterized by a plate configured to selectively open one of the first opening and the second opening and close the other of the first opening and the second opening, wherein the damper is configured to move the plate to guide the cold air generated in the cooler to selectively flow into one of the first cold air passage through the first opening and the second cold air passage through the second opening. a compressor configured to compress and circulate a refrigerant; a cooler configured to generate cold air; a first storage compartment having an internal temperature maintained within a first temperature range; a second storage compartment having an internal temperature maintained within a second temperature range different from the first temperature range; a first cold air passage configured to guide the cold air generated in the cooler to the first storage compartment; a second cold air passage configured to guide the cold air generated in the cooler to the second storage compartment; a partition configured to separate the first cold air passage from the second cold air passage, wherein the first cold air passage is partially defined by a first surface of the partition, the second cold air passage is partially defined by a second surface of the partition, and the first surface is opposite to the second surface on the partition; and a damper comprising: a first opening configured to communicate with the first cold air passage, a second opening configured to communicate with the second cold air passage, characterized by a plate configured to selectively open one of the first opening and the second opening and close the other of the first opening and the second opening, wherein the damper is configured to move the plate to guide the cold air generated in the cooler to selectively flow into one of the first cold air passage through the first opening and the second cold air passage through the second opening. a first opening configured to communicate with the first cold air passage, a second opening configured to communicate with the second cold air passage, characterized by a plate configured to selectively open one of the first opening and the second opening and close the other of the first opening and the second opening, wherein the damper is configured to move the plate to guide the cold air generated in the cooler to selectively flow into one of the first cold air passage through the first opening and the second cold air passage through the second opening.
