Description
A relief damper, also known as a relief air damper or pressure relief damper, is used in ventilation systems to manage excess air pressure and ensure proper system operation. Here’s an overview of its functions and features:
Functions of a Relief Damper
- Pressure Regulation: Relief dampers are designed to release excess air pressure from the ductwork or ventilation system. This helps prevent damage to the system and maintains proper air balance.
- Preventing Overpressure: In systems where the airflow can become too high due to changes in fan speed, system malfunctions, or other factors, a relief damper can open to allow excess air to escape, thus protecting the ductwork and other components.
- Maintaining System Efficiency: By managing excess pressure, relief dampers help to maintain optimal airflow and efficiency in the ventilation system. This can also help in reducing noise and improving overall comfort.
- Emergency Ventilation: In some systems, relief dampers can act as emergency vents to ensure that excess pressure does not compromise the safety of the system or the building.
