Maintenance of air pressure in the staircase area of a multi story building uses controlled vent |
摘要 |
The multi story building has the air pressure in the staircase [1] maintained at a controlled positive level using a fan [5]. Variations are produced due to weather condition changes and also due to doors and windows in apartments [4] being opened. The pressure condition is monitored and a central air vent throttle position [8] is adjusted.
