The structure of the conventional example and its problems Continuation of the conventional example In tunnel ventilation equipment using the ventilation method, as shown in Figures 1 and 2, the tunnel main road (
A plurality of pairs of jet fans (102) are installed at predetermined intervals on the ceiling surface of the air conditioner (101).

充満し、自然流により拡散される。However, in such equipment, when a fire occurs inside the tunnel and the jet fan (102) is stopped, smoke generated at the time of the fire fills the inside of the tunnel and is dispersed by natural flow.
一方、ジェットファン（１０２）を運転させた状態では

煙設備として利用できないという欠点がある。On the other hand, when the jet fan (102) is in operation, the entire cross section of the tunnel main road (101) becomes a smoke flow path, so smoke suddenly flows downstream of the airflow induced by the jet fan (102). This has the disadvantage that it cannot be used as a smoke evacuation system in the event of a fire because it spreads.
