| Abstract: | By the multiple objective optimization, the diffusion angle of the ventilator volutes with high efficiency, low noise and high total pressure of the ventilators was calculated and selected according to the experimental data. Then a specific ventilator was chosen as an example, and by the method of (objective) functions, the diffusion angle of its volute was calculated and analysed to optimize the (operating) performance of the ventilator. |

| Keywords: | diffusion angle performance indices multiple objective optimization |
