The fan is one of the major noise sources of an air conditioner. Because of the presence of other components in the fan assembly, such as the bell-mouth, outlet grille and compressor chamber, the ingested and discharged flow fields around the fan impellers are distinctly different from those in a free field. Therefore, the noise generation mechanisms become much more difficult to analyze and model. This paper concentrates on understanding the generation mechanism and evaluating the noise in the fan system of a split-type air conditioner.
