Abstract:
Provided is a ventilation device that can control a ventilation amount which is in accordance with the activity amount of a person in a room, even if the CO2 concentration of outside air has changed. The present invention comprises: a ventilation unit 170 that exchanges air in an interior space 27 and air in an exterior space, which is a space different from the interior space 27, thereby ventilating the interior space 27; a computation unit 112 that computes a threshold value T, on the basis of a CO2 concentration Coa of the air in the exterior space and a selected operating mode preselected from among a plurality of operating modes; and an operation control unit 113 that, in a case where the CO2 concentration of the air in the interior space 27 is equal to or greater than the threshold value T, controls the ventilation unit 170 so that the ventilation amount is greater than in a case where the CO2 concentration Cra of the air in the interior space 27 is below the threshold value T.
