Abstract: An air treatment system includes a carbon dioxide sensor located in a conditioned space and providing a signal based on detection of an amount of carbon dioxide in the conditioned space; a control system to receive the signal from the carbon dioxide sensor, determine an air flow setting based on the amount of carbon dioxide, and provide a control signal to an air handler based on the air flow setting; and multiple-orifices that create an array of a plurality of air outlets to receive forced air from the air handler and that are substantially parallel to each other and configured to convert a substantially turbulent air flow inside of an air duct into a substantially laminar flow into the conditioned space, wherein the plurality of air outlets are defined by an array of a plurality of passages through a honeycomb structure that are substantially parallel to each other.

Abstract: An air treatment system includes an air handling unit to direct air into a building structure; a sensor to detect the presence of a target material and produce a signal indicative of the detection of a target material greater than a threshold amount; and a control system to control the air handler based on the signal from the sensor.
