Disclosed is a refrigerator incorporating a condenser functioning as a backcover. The condenser is provided in one portion of the outer periphery of a machine room in a lower portion of the refrigerator while the machine is closed in other portions of the outer periphery so that air flow to/from the machine room is enabled only through the condenser to enhance cooling efficient and thus condensing efficient.
