This paper describes servo motor–driven variable-pitch axial flow fan, and its optimal design method, process and application results for improving the efficiency of the variable-pitch fan. The design program for constructing axial flow fan geometry is developed by combining fan blade section design and through-flow performance prediction methods. The optimization technique of this study is Hybrid Metaheuristic Algorithm which is combined with the design program to find optimal design values of blade setting angles, camber angles and chord lengths, and then to maximize the fan efficiency. The axial flow fan obtained in this optimization study shows 6.7% higher design-point efficiency than the initial design and wide operation range with high efficiency by changing the pitch-angle of the fan rotor blade.
