We describe how to find sometimes hidden manual duct dampers, and which way to set the duct damper lever to increase or decrease airflow through various sections of the ductwork and the building. We illustrate using air supply register controls to fine tune airflow in individual rooms or areas.

22 Αυγ 2024 · How Do HVAC Dampers Work? HVAC dampers are essentially valves for airflow. When closed, they act like a river dam, blocking airflow in a home’s ductwork like a dam stops water from flowing in a river. A closed damper will shut airflow to a specific zone that doesn’t need conditioning.
5 ημέρες πριν · Duct dampers, also known as duct zone dampers or air dampers, are mechanical devices used to control and balance airflow in HVAC systems. These dampers are strategically placed within the ductwork and can be adjusted manually or automatically to control the amount of air flowing through specific ducts.
Zone dampers, strategically installed within the ductwork, act as gateways that control the flow of cold air to each zone. When a specific zone calls for cooling, the damper corresponding to that area opens, allowing the conditioned air to flow through, while dampers in other zones may remain closed. This smart zone control prevents overcooling ...
20 Δεκ 2023 · For in duct mounting, size the damper along its outer dimensions (O.D.) or the outer perimeter of the damper’s frame. For on face mounting, use the inner dimensions (I.D.) or the perimeter along inside of the damper frame. For in-duct mounting, measure the damper along the outer dimensions.
Fire dampers interrupt airflow through the duct automatically, restricting the passage of flames. To accomplish their function, these dampers are installed in ducts that cross fire-rated assemblies or fire-rated walls.
20 Ιαν 2022 · When closed, a damper prevents the air from going across it like a dam does with water. HVAC dampers are an important part of your zoning system. They function as valves in the ducts. Their use determines which portion of your property gets heated/cooled air until desired settings are reached.
