Title:
VENTILATION SYSTEM AND AIR-CONDITIONING SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/243071
Kind Code:
A1
Abstract:
This ventilation system comprises: a CO2 concentration detection device that detects the CO2 concentration within a room; a ventilation device that ventilates the room; and a ventilation control device that has a first control mode, in which the ventilation device is set to an operating state when the CO2 concentration is equal to or greater than a first threshold value lower than a ventilation reference value that is a reference value at which ventilation is required, and a second control mode, in which the ventilation device is set to an operating state when it is estimated that the CO2 concentration exceeds the ventilation reference value on the basis of the CO2 concentration and the speed at which the CO2 concentration increases. The ventilation control device performs actions in the first control mode or the second control mode on the basis of the CO2 concentration and the speed at which the CO2 concentration increases.
