  • VENTILATION DEVICE
    Publication number: 20170248149
    Abstract: A ventilation device includes AC voltage estimation unit (32) for estimating an AC voltage, based on a DC voltage detected by voltage detection unit (30) and a current detected by current detection unit (20). Air volume computation unit (24) determines a rotation speed of a motor, based on the AC voltage estimated by AC voltage estimation unit (32) and a target air volume output from a target air volume computation unit.
