Filed: 2016-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a centrifugal fan which automatically corresponds to such a case as to raise rotation number of the centrifugal fan without increasing wind quantity to be supplied and such a case as to suppress flow rate of air on a suction port even when the rotation number of the centrifugal fan is set large.SOLUTION: An impeller in which a plurality of blade pieces are radially arranged for a rotation shaft is stored in a casing, a bell-mouthed suction port is provided on a cover plate which forms one end surface in a shaft direction of the rotation shaft in the casing and a draft air duct is elongated from a circumferential surface of the casing. Further, a channel resistance changing part capable of changing a channel resistance of the suction port is provided and, when prescribed conditions hold, controls the drive of the channel resistance changing part on the control part. As the result, by enlarging the channel resistance of the suction port, not only the rotation number of a centrifugal fan can be raised without increasing wind quantity, but also flow rate of air on the suction port can be suppressed even when the rotation number of the centrifugal fan is set large by lessening the channel resistance of the suction port.SELECTED DRAWING: Figure 4
