MEP Exam 2 Questions with Detailed Verified Answers
What is a central HVAC system? Ans: ✓ ✓ ✓ Conditioned air is generated from one source
What is the most common type of central hvac systems? Ans: ✓ ✓ ✓ Split system (like your house)
What are benefits of using a central hvac system? Ans: ✓ ✓ ✓ - efficient large equipment
- concentrated maintenance
- less noise
- allows lower installed capacity
- can use thermal storage
What is a distributed hvac system? Ans: ✓ ✓ ✓ multiple sources of conditioned air that allow for
easy zoning (RTU)
What is an AHU? Ans: ✓ ✓ ✓ An air handler, or air handling unit (often abbreviated to AHU), is a
device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning
(HVAC) system.

What is a constant air volume system? Ans: ✓ ✓ ✓ In a simple CAV system, the supply air flow rate
is constant, but the supply air temperature is varied to meet the thermal loads of a space. Most CAV
systems are small, and serve a single thermal zone.
What is a variable air volume system? Ans: ✓ ✓ ✓ Unlike constant air volume (CAV) systems,
which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a
constant temperature.
What is a dual duct system? Ans: ✓ ✓ ✓ An air-conditioning system in which two supply ducts run
to each space being conditioned, one for cold air, the other for warm air; at each individually
controlled space, air from the two ducts is blended in a sheet-metal box (called a mixing box) and
then supplied to the conditioned space.
What is a multi zone system? Ans: ✓ ✓ ✓ Hot and cold air is mixed at the air handling unit
What is the hertz frequency in the USA? Ans: ✓ ✓ ✓ 60 hertz
Most chill water systems are piped in which direction? Ans: ✓ ✓ ✓ Parallel
Control valves regulate flow through? Ans: ✓ ✓ ✓ the fan coils
What are the primary hvac equipment and systems? Ans: ✓ ✓ ✓ - the primary sources of heating
and cooling
- chillers and heat rejection
- boiler
- engines and generators
