Abstract:
1. A refrigerator, comprising: a refrigerator main body in which a freezing chamber and a refrigerating chamber are formed to be partitioned; a freezing chamber side evaporator installed at the freezing chamber, for directly cooling the freezing chamber; a refrigerating chamber side evaporator installed in direct contact on a rear surface of an inner wall of the refrigerating chamber, for cooling the refrigerating chamber; a refrigeration cycle including a compressor, a condenser and an expansion means connected to the freezing chamber side evaporator and the refrigerating chamber side evaporator, and performing a cooling operation around the evaporators by circulating refrigerants; a duct being installed on a front surface of the inner wall of the refrigerating chamber to form a cool air circulation passage in an up/down direction, having a suction hole at its one end, and having a plurality of cool air distribution holes at its other side of the suction hole for distributing cool air to the refrigerating chamber; an air blowing device installed at the suction hole of the duct, for blowing the air circulated in the refrigerating chamber to pass through the cool air circulation passage; and a control unit for naturally or forcibly convecting the cool air in the refrigerating chamber by controlling operations of various components including the compressor and the air blowing device.
