The invention provides an air-cooled refrigerator which comprises a box body, an air flue cover plate, an evaporator, a plurality of partitions, a plurality of air inlet air flues, a plurality of air return air flues and an air flue opening-closing device, wherein the partitions can be detachably arranged in a storage part for partitioning the storage part into a plurality of sub rooms; and random adjacent sub rooms are combined into a communicating room by at least partially dismounting the partitions, so that number and volume of all rooms in the storage part are regulated. The air flue opening-closing device can be used for opening or closing the air return air flues according to number and a distribution condition of all rooms in the storage part, so that each room communicates with one air return air flue in an open state. According to the air-cooled refrigerator provided by the invention, the structures of the air flues can be correspondingly changed according to the number and the distribution condition of the rooms of the storage part, so that each room is equipped with a respective independent circulating air flue, and therefore, cold and heat distribution in each room is uniform.
