, 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: -
ANS Plenum
A duct accessory which acts as a valve (or plate) for regulating the flow of air out of the duct. -
ANS 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. - ANS 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. - ANS 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. - ANS CUH
What purpose does the stamped pattern on this plate heat exchanger serve? -
ANS Strenghtens the plate, adds surface area for more efficient heat exchange
There is no difference between PSI and PSIG. - ANS false
