High. The advantage of multi-blade is the larger torque conversion rate, but in terms of energy conversion rate, the efficiency of 4-blade and 5-blade fans is lower than that of 3-blade fans, but there is no special impact. The feasibility of multi-blade breeze power generation is high. Feasibility, in a narrow sense, means that the existing resources and conditions of the enterprise ensure the execution of the production operation plan.
