Variable air volume control system

摘要

A system controls the pressure at which conditioned is to be provided to one or more zones to be heated or cooled by the conditioned air. The system actively computes a setpoint for the pressure with a location in a duct system upstream of where any of the conditioned air is to be provided to the zones. The setpoint is computed as a function of the positional statuses of dampers within the duct system that regulate the flow of the conditioned air to the respective zones. The actively computed setpoint is compared with a sensed pressure in the duct system in order to determine whether the pressure in the duct system needs to be changed.
