Multi-stage regulation and control intelligent precise air supply system and control method

The invention discloses a multi-stage regulation and control intelligent precise air supply system and a control method. The system comprises a cabinet, an air supply fan and a flow guide mechanism, wherein the cabinet is divided into an air supply cavity and a loading cavity. An air inlet is formed in the cabinet body of the air supply cavity, and the air supply fan is correspondingly and fixedlyarranged at the air inlet. The flow guide mechanism comprises a flow guide shutter correspondingly arranged at an air outlet of the air supply fan and a driving mechanism for driving the flow guide shutter to turn over so as to change an air outgoing angle. The cooling capacity in the cabinet can be distributed according to needs through the driving of the flow guide shutter, the problem of localoverheating of a single cabinet of a data center is effectively solved, power consumption is effectively reduced, and the purpose of saving energy is achieved. Moreover, the system effectively solvesthe problem that a heating
