Is the hotel exhaust fan installed in the stairwell?

Not so good. According to relevant data, stairwells are generally the main channels for fire and smoke diffusion. If the exhaust fan is improperly installed or operated, it will affect the air quality in the stairwell and the fire escape. When the exhaust fan is working, the noise will interfere with the daily life of residents. Especially at night, noise is more noticeable.
