Aiming at the problem of low-efficiency and high noise in a type of multi-blade centrifugal fan, an improved scheme on the angle of blade outlet and volute was put forward to make a new prototype model. Comparing original-design fan and the newly designed fan, based on the Performance testing, the results shows that aerodynamic performance and noise performance is greatly improved of the newly designed fan which reaches national standard of Class 1 energy consumption.
