Beschreibung
Zusammenfassung:	A ventilator includes: a blower unit (23) that exchanges indoor air; a corrected threshold calculation unit (312) that calculates a corrected threshold by correcting a predetermined threshold of CO2 concentration in the indoor air for changing a ventilation air volume on the basis of a detected outdoor air CO2 concentration value that is CO2 concentration in outdoor air detected; and a ventilation air volume control unit (313) that changes the ventilation air volume by controlling an air volume of the blower unit (23) on the basis of the CO2 concentration in the indoor air and the corrected threshold. The ventilator has an effect of being able to maintain an appropriate ventilation air volume corresponding to an amount of human activity even when the CO2 concentration in the outdoor air changes.
