What are registers equipped with that allow them to mix air in the conditioned space?

• A. Air volume control devices
• B. Duct dampers
• C. Temperature sensors
• D. Humidity inserts

Answer: (A)

The ability to mix air in the room comes from an air volume control device built into the register. This damper or adjustable blade inside the register lets you vary how much supply air enters the space, which influences how the incoming air blends with the room air to promote even temperature and comfort. Duct dampers live in the ducts and control flow between branches, not mixing within the room. Temperature sensors only measure temperature, and humidity inserts aren’t standard means of mixing air in the space.
