Which term refers to the device that regulates the amount and/or the temperature of the controlled medium?

• A. Testing
• B. Terminal Unit
• C. Static Head
• D. Suction Head

Answer: (B)

The term describes the device that directly controls how much of the medium is delivered and what its temperature is at the point of use. Terminal units sit at the end of the distribution system and regulate the flow and conditioning of the medium going into the space, typically by adjusting dampers, coils, or valves. Examples include VAV boxes, fan-coil units, and mixing boxes, all of which modulate both quantity (air or water flow) and temperature as required. Static head and suction head relate to pressures in piping or pump systems, not to devices that regulate flow or temperature. Testing is a separate activity, not a regulating device.
