The invention relates to an air supply device and a refrigerator with the air supply device. Particularly, the air supply device provided by the invention comprises a
peripheral wall part, a first axial end part and an adjusting part, wherein a plurality of first air outlets are arranged in the
peripheral wall part; the first axial end part is arranged at one end of the
peripheral wall part, and at least one second air outlet is arranged in the first axial end part; and the adjusting part is rotatably arranged relative to the peripheral wall part so as to fully block, partially block and fully
expose each first air outlet in different movement positions, thereby adjusting the respective air supply area of the plurality of first air outlets. The air supply device and the refrigerator have the advantages that the quantity of
cold air entering a storage chamber can be adjusted in a unified manner, and the
cold air can also be fed into another storage chamber; the structure is special and simple; and the demand of
cold air in a refrigerating chamber can be ensured, and the temperature of different parts in a
freezing chamber can also be adjusted in real time, so that the
nutrient losses of food are prevented,
power consumption is reduced, and energy is saved.
