WIPO Patent Application WO/2021/100664
Kind Code:
A1
Abstract:
In an air conditioner that performs a ventilation operation on the basis of the concentration of a predetermined gas in a room, there is no conventional guideline on how to make a normal air conditioning operation and a ventilation operation coexist. This air conditioning system (100) has a ventilation fan (54), a control unit (16), and an operation terminal (60). The control unit (16) has a forcible ventilation operation mode in which the concentration of the predetermined gas in the room is acquired, and when the acquired concentration of the predetermined gas exceeds a predetermined value, a forcible ventilation operation is automatically started in which the ventilation fan (54) is controlled to ventilate the room to lower the concentration of the predetermined gas in the room. The control unit (16) continues the forcible ventilation operation even when receiving an air conditioning operation starting command.
