| Abstract: | By means of the entropy theory, the energy dissipation of a centrifugal fan at the off design point is investigated. The efficiency of a centrifugal fan at the off designed operating point and the relevant factors are also analyzed in theory and in practise. It is proposed that swirling flow and swirling is main reason of energy dissipation a centrifugal fan at the off designed operating point. A method for energy conservation of a centrifugal fan at this point is found in this paper. |
