ABSTRACT:
A system for providing air quality control for an indoor area divided into a plurality of zones, whereby air quality is controlled both centrally and at each of the zones, including a central controller, a central damper, a supply air stream duct, a return air duct, a plurality of zone controllers, a plurality of zone dampers, a plurality of air quality sensors (i.e., CO.sub.2, volatile organic compounds, humidity, etc. . . ) and a plurality of temperature sensors. A method for providing air quality control for an indoor area divided into a plurality of zones, whereby air quality is controlled both centrally and at each of the zones, including the steps of: reading an output value of an air quality sensor from one of the zones, comparing the output value with a zone maximum threshold value and a zone minimum threshold value, modulating the zone damper to vary a supply air flow into the zone, repeating the first three steps for each zone, determining a predetermined function (i.e., average, maximum, minimum, etc. . . ) of the output values from all of the zones, comparing the function of the output values with a central maximum threshold value and a central minimum threshold value, and modulating the central damper to vary the flow of outside air into the supply air stream.
