Intelligent air supply system for server-level cabinet and control method

The invention discloses an intelligent air supply system for a server-level cabinet and a control method. The system comprises a cabinet, and the cabinet is divided by an air valve disposed in the cabinet into an air supply cavity and a loading cavity. An air inlet and an air outlet are respectively formed in the cabinet body in a manner of being corresponding to the air supply cavity and the loading cavity. The air valve comprises a supporting frame and a plurality of air valve units arranged in the supporting frame, and each air valve unit comprises an air valve plate arranged on the supporting frame and a driving motor which is in transmission connection with the air valve plate to drive the air valve plate to turn over to change the ventilation amount. According to the invention, the control method employs overall heat dissipation as a reference basis, can achieve the key heat dissipation in a high heat dissipation area, improves the control accuracy and safety with the assistanceof the reference of the a
