DISCLOSED IS A REFRIGERATOR HAVING A COOL AIR DISPERSING DEVICE (30). A DUCT, HOUSING (20) FORMING A COOL AIR DUCT (15) IS INSTALLED ON A REAR PART OF A COOLING COMPARTMENT, AND MANY COOL AIR DISCHARGE PORTS (16,16A,16B,16C) OPEN INTO THE COOLING COMPARTMENT ARE FORMED ON THE DUCT HOUSING (20). IN THE COOL AIR DUCT (15) ARE INSTALLED MANY COOL AIR DISPERSING BLADES (41) OF PLANAR PLATE SHAPE CORRESPONDING TO THE DISCHARGE PORTS RESPECTIVELY AND CAPABLE OF ROTATING. THE BLADES (41) CONTROL A DISCHARGE DIRECTION OF COOL AIR SUPPLIED INTO THE COOLING COMPARTMENT ACCORDING TO A ROTATIONAL POSITION THEREOF. THE BLADES (41) HAVE A SIZE SIMILAR TO THE DISCHARGE PORTS (16), AND CAN CLOSE THE DISCHARGE PORTS (16,16A,16B,16C) AT A PREDETERMINED ROTATIONAL POSITION THEREOF. WHILE A COOLING SYSTEM IS NOT OPERATING, THE DISCHARGE PORTS (16,16A,16B,16C) ARE CLOSED BY THE BLADES (41), WHEREBY THE BACKFLOW OF AIR IN THE COOLING COMPARTMENT TOWARD AN EVAPORATOR IS PREVENTED, AND LESS FROST IS GENERATED ON THE EVAPORATOR.
