Mep exam Questions and Answers
100% Pass
Which of the following is NOT one of the 5 basic "requirements" of comfort? - ✔✔IAQ
Large Forced-Air mechanical unit which conditions 100% outside air. - ✔✔MAU
The process of moving air within a space to prevent air from becoming stagnant. -
✔✔circulation
Which type of ductwork is most commonly used due to its durability and its limited
concern of mold and bacteria growth? - ✔✔Sheet Metal Duct
Why is IAQ such a difficult concept to understand and manage? - ✔✔There are few
rules/laws about IAQ
b.
There are many variables involved in each situation
c.
IAQ concepts often contradict equipment efficiency and LEED requirements
Calculates cooling and heating capacity over a certain time. - ✔✔Btuh
In a forced air system, a pressurized chamber that contains gas (typically just air) at a
positive pressure which is used instead of ductwork to distribute air throughout a space
is known as: - ✔✔Plenum

, A duct accessory which acts as a valve (or plate) for regulating the flow of air out of the
duct. - ✔✔Damper
In a typical high-efficiency furnace, air has to go through 5 basic steps/components/etc.
before cycling back through the building. After return air enters from a duct, put the
following components in order (1 being first, 5 being last) of when the air passes by, or
through, them before it enters the supply air duct. - ✔✔Filter, Blower, Secondary Heat
Exchanger, Combustion Chamber, Primary heat exchanger
A forced -air system used for both heating and cooling, which moves heat from the
surrounding air either into, or out of, a building depending on the need. It does not
generate additional heat (no combustion) but requires a moderate climate to be efficient.
- ✔✔heat pump
A type of forced air unit which does not require ductwork, heats only single areas, and
is common in areas that aren't utilized full-time or is inefficient to run a ducted
mechanical system to on a regular use basis. - ✔✔CUH
What purpose does the stamped pattern on this plate heat exchanger serve? -
✔✔Strenghtens the plate, adds surface area for more efficient heat exchange
There is no difference between PSI and PSIG. - ✔✔false
In a forced air system, a pressurized chamber that contains gas (typically just air) at a
positive pressure which is used instead of ductwork to distribute air throughout a space
is known as: - ✔✔Plenum
A two-pipe hydronic system which has a supply and return line, and the return line
provides the shortest path back to the boiler for the liquid (first unit supplied is the first
unit returned, and vice versa). - ✔✔Direct Return System
