The present invention relates to a refrigerator having a centrifugal fan-duct assembly including a body having a storage room therein; and the centrifugal fan-duct assembly in the storage room, configured to separate a flow of cool air and a flow of defrosted water from each other, in order to prevent freezing in the cool air passage. Since the flow and/or directions of cool air and the defrosted water are different and/or separate from each other, the cool air passage is prevented from freezing.
