Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draught of boilers and industrial furnaces; the centrifugal fan for cooling and ventilating in air conditioning equipment and household appliances is based on the principle that kinetic energy is converted into potential energy, and utilizes an impeller rotating at high speed to accelerate gas, then decelerate and change flow direction so as to convert kinetic energy into potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from an axial direction, changes to a radial direction as it flows through the impeller, and then enters the diffuser. The gas changes flow direction and the increase in cross-sectional area of the conduit slows the gas flow, which converts kinetic energy into pressure energy.
