The present invention discloses an air volume adjustment device for a refrigerator. The air volume adjustment device comprises: a fan capable of introducing cold air from an evaporator into the first air inlet cavity and the second air inlet cavity; a baffle arranged between a first air inlet cavity of a first compartment and a second air inlet cavity of a second compartment, which is capable of moving among a plurality of positions to adjust the volume of air entering the first air inlet cavity and the second air inlet cavity; and an operating knob and a potentiometer which are connected to the front side and the rear side of the baffle, respectively. The operating knob is capable of operably driving the baffle to move. The potentiometer transfers an electrical signal corresponding to a position of the baffle to the controller for controlling the fan or the compressor.
