Abstract
Controlling a fresh air intake includes determining a fresh air intake damper position based on the supply air flowrate, a measure of energy delivered to the supply air flow, or a measure of humidity of the supply air flow. Determining the fresh air intake damper position is subject to a constraint that the AHU maintains one or more comfort conditions in the building space and one or more of a constraint regarding maintaining one or more Indoor Air Quality (IAQ) contaminants in the building space below one or more IAQ thresholds, minimizing energy consumption of the AHU, and maximizing the fresh air ventilation air flow into the building space. Various parameters used to determine the fresh air intake damper position may be derived from available sensed conditions so as to reduce the number of physical sensors that are required.
