The negative pressure fan in the air intake part blows air into the inner space, so that the air pressure inside the space is less than the outside air pressure, so that the outside air can enter the space, and then the fresh air flow can be poured into the classroom through the pipe. On the other hand, the negative pressure fan blows outward, so that the local air pressure at the exhaust outlet is less than in the space, so that the exhaust gas in the classroom can be discharged to the outside through the exhaust pipe through the air pressure difference.
