Abstract
Particular embodiments of the inventive technology present a method for optimizing fan performance by, e.g., adjusting fan efficiency and/or acoustics to match, or more closely match, system design requirements or preferences. Embodiments may involve the selection of a size of centrifugal fanfrom the plurality that can fit inside a certain housing, forming a fan unit that provides an annular output; such selection may be made to achieve certain performance goals. Add-on appurtenances such as one or more of, e.g., an annular housing extension, fixed vanes, and acoustic treatment, may be used to tailor the fan unit to meet system requirements, e.g., regarding efficiency, acoustic/sonic performance (e.g., noise generated by the fan), and/or static efficiency.
