Abstract
Provided is a refrigerator including: a carbonated water tank in which carbonated water is stored; a water tank supplying filtered water to the carbonated water tank; a carbon dioxide cylinder supplying carbon dioxide to the carbonated water tank; and a controller, if the water level of carbonated water sensed by a water level sensor is less than or equal to a predetermined minimum water level, supplying the filtered water to the carbonated water tank, and if supply of the filtered water is completed, supplying the carbon dioxide to the carbonated water tank so as to produce the carbonated water. If it is expected that the storage amount of the carbonated water is reduced or the user won't use the carbonated water for a while, carbonated water is automatically produced so that the user is not required to wait while the carbonate water is produced.
