Title:
AIR CONDITIONING SYSTEM AND VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146121
Kind Code:
A1
Abstract:
The present invention aims to obtain an air conditioning system that is capable of reducing power consumption due to ventilation. The air conditioning system (1) comprises: a ventilation device (2) that ventilates a room and has an exhaust fan (22) that feeds air taken in from inside the room to outside the room, an air supply fan (23) that feeds air taken in from outside the room to inside the room, and a control unit (20) that controls the ventilation air flow resulting from the operation of the exhaust fan (22) and the air supply fan (23); and a human sensor (35) that detects the presence of a person inside the room. The control unit (20) is capable of switching ventilation air flow between a first air flow and a second air flow that is greater than the first air flow. If the presence of a person is not detected by the human sensor (35), the ventilation air flow is set to the first air flow.
