Abstract
A ventilator includes: a blower unit that exchanges indoor air; a corrected threshold calculation unit that calculates a corrected threshold by correcting a predetermined threshold of COconcentration in the indoor air for changing a ventilation air volume on the basis of a detected outdoor air COconcentration value that is COconcentration in outdoor air detected; and a ventilation air volume control unit that changes the ventilation air volume by controlling an air volume of the blower unit on the basis of the COconcentration in the indoor air and the corrected threshold.
