Abstract

See full text

An active stairwell compensation system includes air injection points at different elevations in a stairwell; a fan for providing airflow to the air injection points; sensors; air injection dampers; and a controller in data communication with the fan, the sensors, and the air injection dampers. At least some of the sensors are located inside the stairwell, and at least some of the sensors are located outside the stairwell. A respective air injection damper is located between each air injection point and the fan. The controller has programming to utilize data from the sensors to adjust an amount of air provided by the fan and independently adjust the air injection dampers to maintain a desirable amount of air pressure at the air injection points. The desirable amount of air pressure is selected to prevent smoke from entering the stairwell while allowing stairwell doors to open for egress.
