A refrigerator having a ventilating device, the ventilating device comprising: a ventilation fan for ventilating air; a first duct for allowing some of the air discharged from the ventilation fan to flow therealong; a second duct for allowing the remaining air, excluding the air discharged from the ventilation fan and flowing along the first duct, to flow therealong; and a scroll for guiding the air discharged from the ventilation fan to the first duct and the second duct, wherein the interior of the scroll is formed in a spiral shape, wherein the first and second ducts (130, 140) have a portion in which they extend parallel to each other and the air flows in the same direction in the two ducts (130, 140), and wherein the rotation axis of the fan is horizontal and the two ducts (130, 140) extend vertically and upwardly from the scroll in the portion in which their extension is parallel, wherein the ventilation fan is mounted in the scroll and is a centrifugal fan that sucks the air in an axial direction of the ventilation fan and discharges the air in a radial direction of the ventilation fan, wherein the first duct and the second duct are fluidly connected to the scroll at two respective positions that are adjacent to each other in the circumferential direction of the ventilation fan and that both lie above the rotation axis of the fan, wherein, as seen in a cross-section of the ventilating device by a plane that is orthogonal to the rotation axis of the fan, a vertical line drawn upwardly from the center point of the ventilation fan intersects an entrance of one of the two ducts (130, 140), the refrigerator being characterised in that the scroll is constructed in a structure in which the distance between a cutoff part and the outer circumference of the ventilation fan is 2 to 8 % of the diameter of the ventilation fan, and in that, as seen in said cross-section, the angle between said vertical line and an imaginary straight line interconnecting the center point of the ventilation fan and the cutoff part is 35 to 45 degrees. a ventilation fan for ventilating air; a first duct for allowing some of the air discharged from the ventilation fan to flow therealong; a second duct for allowing the remaining air, excluding the air discharged from the ventilation fan and flowing along the first duct, to flow therealong; and a scroll for guiding the air discharged from the ventilation fan to the first duct and the second duct, wherein the interior of the scroll is formed in a spiral shape, wherein the first and second ducts (130, 140) have a portion in which they extend parallel to each other and the air flows in the same direction in the two ducts (130, 140), and wherein the rotation axis of the fan is horizontal and the two ducts (130, 140) extend vertically and upwardly from the scroll in the portion in which their extension is parallel, wherein the ventilation fan is mounted in the scroll and is a centrifugal fan that sucks the air in an axial direction of the ventilation fan and discharges the air in a radial direction of the ventilation fan, wherein the first duct and the second duct are fluidly connected to the scroll at two respective positions that are adjacent to each other in the circumferential direction of the ventilation fan and that both lie above the rotation axis of the fan, wherein, as seen in a cross-section of the ventilating device by a plane that is orthogonal to the rotation axis of the fan, a vertical line drawn upwardly from the center point of the ventilation fan intersects an entrance of one of the two ducts (130, 140), the refrigerator being characterised in that the scroll is constructed in a structure in which the distance between a cutoff part and the outer circumference of the ventilation fan is 2 to 8 % of the diameter of the ventilation fan, and in that, as seen in said cross-section, the angle between said vertical line and an imaginary straight line interconnecting the center point of the ventilation fan and the cutoff part is 35 to 45 degrees.
