WebSystems employing variable air volume are most energy efficient. These include VAV, VAV reheat, VAV dual duct, VAV multizone, and VAV fan terminal units. They use only as much air and fan power as required to satisfy load and minimize waste due to reheat or mixing of warm and cold air. WebAir terminal units (ATU) are zone-level air distribution devices that regulate airflow for maximum occupant comfort. The ATU controls the zone space temperature to maintain a desired occupied space temperature. In variable air volume (VAV) systems, the flow of air is supplied by a single air handling unit. Besides the ducts themselves, complete ducting systems contain many other components. A duct system often begins at an air handler. The blowers in the air handler can create substantial vibration, and the large area of the duct system would transmit this noise and vibration to the inhabitants of the building. To avoid this… evelyn lozada makeup made by mac
