The invention provides a method and system for air blower energy recovery control and a storage medium. The method comprises an air blower, a power supply, a frequency converter, a first contactor, a second contactor, a DC / DC converter, a storage battery, a UPS and a PLC, wherein the power supply is connected with a main circuit of the frequency converter through the first contactor; the UPS is connected with the power supply, the storage battery, the second contactor and the PLC, and the UPS is used for supplying power to the second contactor and the PLC based on electric energy provided by the power supply or the storage battery; the PLC is used for controlling the opening and closing states of the first contactor and the second contactor; and the air blower is sequentially connected with the frequency converter, the second contactor, the DC / DC converter and the storage battery, when a main loop of the frequency converter loses power and the second contactor is closed, the kinetic energy of the air blower can be converted into electric energy through the frequency converter, the electric energy is output to the DC / DC converter through the second contactor, and the electric energy is stably output to the storage battery after being converted by the DC / DC converter. According to the method and system for air blower energy recovery control and the storage medium, the energy of the magnetic suspension centrifugal air blower can be recovered, and the energy loss is reduced.
