HVAC dampers typically help control and regulate airflow by managing how much air flows through certain areas of your space. They can help conserve energy and create more consistently maintained temperatures in specific rooms by preventing temperature fluctuations in one area of the house from affecting others.
There are also fire and smoke dampers that are safety measures in the event of a fire that should be a part of your HVAC system. They are installed within the ductwork of your system to help prevent the spread of fire and smoke through the HVAC system.
What Are Fire Dampers?
Fire dampers are devices installed in ducts and air transfer openings designed to automatically close upon the detection of heat. They are also intended to interrupt airflow, resist the passage of flame, and maintain the integrity from one side of a fire-rated separation to the other.
Fire dampers are triggered by high temperatures; typically, they’re designed to have a fusible device, a link that melts at a certain temperature. On reaching the melting point, the link melts, and the blades it was holding then close and prevent the fire from moving beyond that point.
Fire dampers are required by building codes and regulations in structures where fire barriers and compartmentalization are mandated for safety reasons. Duct fire dampers are an essential safety feature to limit the spread of fire and protect occupants.
What Is the Purpose of a Smoke Damper?
A smoke damper is used to limit the passage of smoke through the HVAC system or from one side of a fire-rated separation to the other. They operate automatically using a smoke detection system, or sometimes they can be operated remotely by a fire command station.
Smoke dampers should be installed either in the smoke barriers or adjacent to them. They are installed in ducts passing through, or air outlet openings terminating at, smoke barriers, shaft walls, horizontal exit walls, corridor walls, corridor ceilings, and other barriers designed to resist the spread of smoke as required by a building or life safety code and other applicable standards.
What Do HVAC Dampers Do?
HVAC dampers are small valves or plates that regulate airflow within the HVAC system. It works by closing or opening to certain degrees to control airflow to different rooms, or zones, within the structure. They can help conserve energy while maintaining comfortable temperatures in the space.
Are Dampers Necessary for HVAC?
Dampers are generally found in zoned HVAC systems and are used to create a smooth flow of air from one room to another. By regulating the airflow in a system, dampers help create consistency when the HVAC unit is running, which can help extend the life of the system. HVAC dampers are a smart investment in extending the health of your unit as well as saving on your heating and cooling expenses.
