Classification: CPC F  G | IPC F

Claim 1:
2. The air conditioning and ventilating system according to claim 1, wherein
the ventilation device includes the supply air fan configured to supply the outside air to the room and the exhaust fan configured to exhaust the air in the room to outside the room,
the airflow volume detector includes a supply airflow volume detector configured to detect a supply airflow volume equivalent value by the supply air fan, and an exhaust airflow volume detector configured to detect an exhaust airflow volume equivalent value by the exhaust fan, and
the processor of the controller executes fixed airflow volume control to adjust a number of revolutions of the supply air fan and the exhaust fan to cause the supply airflow volume equivalent value and the exhaust airflow volume equivalent value to approach respective target airflow volumes, and sets the operation of the air conditioning device to the stop state on determination that at least one of the supply airflow volume equivalent value and the exhaust airflow volume equivalent value is equal to or less than the first predetermined value during the fixed airflow volume control.
