Which term refers to an enclosed space designed to capture and discharge or circulate air within a building or appliance?

• A. Plenum
• B. Safety Data Sheets
• C. Gravity System
• D. Commodity

Answer: (A)

A plenum is an enclosed space that collects and distributes air for circulation within a building or appliance. In HVAC systems, air is drawn into a return plenum or fed from a supply plenum, which serves as a central chamber connected to ducts to discharge or circulate air. This design enables controlled ventilation, distribution, and air handling throughout the space, such as the area above a drop ceiling or inside ductwork. Safety Data Sheets describe chemical hazards, a Gravity System refers to movement driven by gravity (often in plumbing), and Commodity means a basic good; none of these convey the idea of an enclosed air-capture and distribution space.
