Abstract
A control unit determines, on the basis of a temperature and humidity detected by sensors, whether outdoor air cooling that takes outdoor air into a room is effective. Upon determination that the outdoor air cooling is effective, the control unit opens a damper and causes stoppage of an air supply fan disposed in an air supply path. Due to such operation, indoor air passing through an air discharge path bypasses a total heat exchanger by passing through a bypass air path, and thereby is discharged to the outdoors as exhaust air. However, due to stoppage of the air supply fan, although the outdoor air does not flow through the air supply path, the outdoor air flows into a building from an opening of the building.
