What could happen if a damper is not powered properly?

• A. The damper stays closed
• B. The damper may remain open
• C. The damper operates inconsistently
• D. The damper will not function at all

Answer: (B)

The correct answer is that if a damper is not powered properly, it may remain open. Dampers are used in HVAC systems to control airflow, and they rely on a power source for their operation. If a damper does not receive adequate power, it could fail to close when required, leading to unrestricted airflow through that system. This can result in improper temperature control, increased energy consumption, and inefficiencies in the overall HVAC system performance. When dampers remain open, it can also lead to airflow imbalances, affecting the comfort levels in different zones of a building. This scenario can create issues such as drafts or over-conditioning of particular areas, which is why ensuring that dampers are properly powered is crucial to maintain efficient and effective building operations. In contrast, a damper that is continuously closed or operates inconsistently would suggest different underlying issues, such as mechanical failure or control system errors, rather than a direct result of improper power conditions.
