System and/or method for monitoring and/or controlling the relative internal air pressure of a facility

Abstract

A system is provided for maintaining a balanced interior air pressure in a building (10) having a plurality of different localized areas (20). The system includes: a main fan or set of main fans (12) that is selectively controlled to support a desired overall interior air pressure inside the building (10); a plurality of interior sensors (22), each interior sensor (22) arranged to detect a localized air pressure at one of the areas (20) in the building; a plurality of auxiliary fans (26), each auxiliary fan (26) being provisioned to selectively modify the localized air pressure at one of the areas (20) in the building (10); and, a control unit (11) that is in operative communication with the plurality of sensors (22) to obtain air pressure readings therefrom, in operative communication with the plurality of auxiliary fans (26) to control operation thereof, and in operative communication with the main fan or set of main fans (12) to control operation thereof. Suitably, based upon the localized air pressure detected by a given sensor (22), a corresponding auxiliary fan (26), provisioned for the area in which the air pressure was detected by the given sensor (22), is controlled by the control unit (11) to modify the localized air pressure at the area (20) in the building (10) for which the corresponding auxiliary fan (26) was provisioned.
