Abstract: A refrigerator includes a storage space, an evaporator configured to cool air in the storage space based on heat exchange of a refrigerant, and a defroster configured to remove frost formed on the evaporator. The defroster incudes a pipe extended around the evaporator and including a circulation channel through which working fluid circulates, a fluid storage including a first opening and a second opening respectively communicating with opposite end portions of the pipe and configured to store the working fluid, and a pumping part disposed at a selected position on the circulation channel of the pipe between the evaporator and the fluid storage and configured to vaporize the working fluid to circulate the vaporized working fluid in the circulation channel.
