A method for driving a cooling fan of a chilled air circulation device for a vegetable refrigerator is provided to change a driving rpm of the cooling fan according to conditions set by a user by sensing storage state and internal temperature of a storing compartment, thereby improving chilled air circulation efficiency and keeping the internal temperature stably. A method for driving a cooling fan of a chilled air circulation device for a vegetable refrigerator includes four modes in the driving of the cooling fan, when a user sets a storage state of a storing compartment as keeping, aging, and freezing. In the keeping state, if cavity temperature is higher than reference temperature, it is determined as an overload state and the cooling fan is set to a first mode. In the other case, the cooling fan is set to a second mode for normal state. In the freezing state, the cooling fan is set to a third mode if a compressor is in operation, and a fourth mode if the compressor is not in operation. In the aging state, the cooling fan is not driven. As the aging is continued for 24 hours, then the cooling fan is driven in the same manner with the keeping mode.
