The variable air volume adjusting control method based on the rotatable air door comprises the steps that whether a refrigerating chamber has the refrigerating requirement or not is detected, and when the refrigerating chamber has the refrigerating requirement, a refrigerating chamber refrigerating instruction is generated; based on the refrigerating chamber refrigerating instruction, a rotatable air door arranged at an air inlet in advance is controlled to be fully opened to run for first preset time; the temperature of a refrigerating chamber of the refrigerator is detected in real time, a preset opening angle value of a rotatable air door corresponding to the temperature of the refrigerating chamber is searched according to the temperature of the refrigerating chamber, the opening angle of the rotatable air door arranged at an air inlet is controlled and adjusted in real time, and the opening angle of the rotatable air door is in direct proportion to the temperature of the refrigerating chamber.
