The control box 70 is used for collecting ignition signals and controlling the opening degree of the electric air valve 5, and transmitting the collected signals and the working state to the control host 72. The control host 72 synthesizes the signals and the working state of each control box 70, obtains the frequency required by the variable frequency controller 7 through an algorithm, and adjusts the power of the electric fan. The communication between the control box 70 and the control main sentence is networked in a wireless or wired manner.
In another embodiment of the present invention, the algorithm for controlling the electric fan by the control host 72 is described as follows:
presetting a position factor a according to the position of the air inlet 32 in the air duct;
presetting the lowest working frequency C of the air duct according to the length from the air outlet 34 to the position closest to the air inlet 32;
the full open is measured to achieve the use effect, and the highest working frequency D of the frequency converter is set;
freq is the calculated target frequency, α represents the open electropneumatic damper 5 and β represents all electropneumatic dampers 5.
