What is the primary purpose of dynamic smoke dampers in HVAC systems?

• A. Temperature regulation
• B. Smoke control
• C. Humidity control
• D. Air filtration

Answer: (B)

The primary purpose of dynamic smoke dampers in HVAC systems is smoke control. These dampers are specifically designed to detect and respond to the presence of smoke in the air, thereby preventing its spread and protecting building occupants and property. In a building fire, dynamic smoke dampers automatically close to contain smoke within specific areas, thereby assisting in maintaining clear paths for evacuation and enhancing the effectiveness of smoke evacuation systems. This function is critical for life safety as well as property protection, aligning with standards established by the National Fire Protection Association (NFPA). Effective smoke control minimizes the risk of smoke inhalation, which is a significant cause of injury and death during a fire incident.
