[0002] With the rapid development of urban construction, the number of cars has increased rapidly, and the problem of ground parking has become increasingly prominent. Building underground garages has become one of the main measures to solve this problem. Since underground garages generally have no other holes connected to the outdoors except for car entrances and exits, a daily ventilation system must be set up to exhaust dirty air and replenish fresh air in a timely manner. At the same time, due to the high airtightness of underground garages, high-temperature smoke will spread rapidly in the underground garage when a fire occurs because there is nowhere to discharge it, so a fire smoke exhaust system must also be set up.
