1. A fan blade motor matching method of a duct machine comprises the following steps:

  • obtaining a plurality of primary selection schemes formed by different matching modes of the motor and the axial flow fan blades based on the performance requirements of the air duct machine, the number of available axial flow fan blades and the number of motors;

    testing the plurality of initial selection schemes to obtain a plurality of numerical values of preset process parameters;

    comparing the numerical values, performance characteristics and/or cost of the preset process parameters of the primary selection schemes, and selecting the primary selection scheme meeting the preset conditions as an optimal fan blade motor matching scheme;

    wherein, before forming the primary selection scheme, the method further comprises the following steps;

    determining the number of available axial flow fan blades of the air duct machine according to the air volume requirement of the air duct machine;

    judging whether the number of the axial flow fan blades available for the air duct machine is 1 or not;

    if the number of the axial flow fan blades is 1, directly determining a matching scheme of coaxial connection of the single fan blade and the single fan as an optimal fan blade motor matching scheme;

    if the number of the axial flow fan blades is larger than 1, a plurality of primary selection schemes are formed, and the primary selection schemes comprise;

    the fan blade motor matching scheme that each motor only drives one axial flow fan blade specifically comprises the following steps;

    two-way fan blade motor coaxial coupling scheme of air-out formula, two-way air-out tuber pipe machine in this scheme includes;

    the air conditioner comprises a shell, at least one motor and at least one axial flow fan blade driven by the at least one motor, wherein the at least one motor and the at least one axial flow fan blade are arranged in the shell, air outlets are formed in two different directions of the shell, and two different air outlet and return directions are realized by changing the driving direction of the at least one motor.
