Title:
VENTILATION DEVICE AND VENTILATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/053946
Kind Code:
A1
Abstract:
This ventilation device is provided with: an air delivery unit (23) for replacing indoor air; a corrected threshold calculation unit (312) for calculating a corrected threshold by correcting, on the basis of an outdoor air CO2 concentration detection value which is a detected outdoor air CO2 concentration, a predetermined threshold of an indoor air CO2 concentration, which is used to change the volume of ventilation air; and a ventilation air volume control unit (313) for changing the volume of ventilation air by controlling the volume of air from the air delivery unit (23) on the basis of the indoor air CO2 concentration and the corrected threshold. The ventilation device provides an effect with which an appropriate volume of ventilation air flow which corresponds to the amount of activity of a person can be maintained even if the outdoor air CO2 concentration changes.
