The invention discloses an air-cooled refrigerator and a control method thereof, and relates to the technical field of refrigerators. The air-cooled refrigerator and the control method are invented for solving the problems that in the prior art, the refrigerator refrigerating chamber temperature uniformity is poor, and consequently foods are prone to being refrigerating or dried. The air-cooled refrigerator comprises a refrigeration air flue which is communicated with a refrigerating chamber of the refrigerator through an air outlet set arranged on an air flue front cover plate, and the air outlet set comprises a left-side air outlet, a right-side air outlet and a middle air outlet; and an air door assembly is further included and is controlled to open or close the middle air outlet. The control method can be used for refrigerating chamber temperature regulation.
