Supply air refers to?

Supply air refers to?

• A. Air leaving the air handler.
• B. Air entering the air handler.
• C. Air within the building.
• D. Air at the coil.

Answer: (A)

Supply air is the conditioned air that is delivered to the occupied spaces. It exits the air handler, travels through the supply ducts, and comes out of vents into the rooms after being cooled or heated and then distributed. This is what you feel when you stand under a supply vent—the air that’s being sent into the building. Air entering the air handler is the air the system pulls in (return air or outside air) to be conditioned, not yet delivered to the spaces. Air within the building refers to the general room air before it has been supplied, and air at the coil is the air just passing over the heating or cooling coil inside the air handler—still not yet distributed as supply air.
