Fire dampers with labels indicating maximum velocity and pressure differential are intended for what type of HVAC systems?

• A. Static systems
• B. Dynamic systems
• C. Hybrid systems
• D. Closed-loop systems

Answer: (B)

Fire dampers with labels indicating maximum velocity and pressure differential are designed specifically for dynamic systems. In HVAC applications, dynamic systems refer to those that involve airflow movement, such as systems with fans that actively circulate air throughout a building. These systems experience fluctuating pressure and air velocity during operation, which necessitates the use of fire dampers that can effectively function under varying conditions. The maximum velocity and pressure differential markings on the dampers provide essential information to ensure they can withstand the forces and speeds present within dynamic airflow environments, ensuring they perform safely and effectively when a fire situation occurs. By maintaining their operational integrity under these conditions, dynamic fire dampers can help to contain smoke and heat, thereby playing a crucial role in fire protection strategies within buildings.
