    Abstract: A centrifugal fan having improved efficiency and noise reduction includes a hub configured to have a central part combined with a rotary shaft, a shroud spaced apart from the hub, and a plurality of blades provided between the hub and the shroud. The shroud includes outer circumferential parts each connecting the trailing edges of a plurality of respective adjacent blades. Each outer circumferential part is asymmetrically formed based on the center of the outer circumferential part.
