POUL 1010E BUNDLED EXAM 2025 UPDATED
QUESTIONS AND ANSWERS SOLVED 100%
◉Where do you view the rotation and discharge of a centrifugal fan?
Amswer: On the drive side
◉Why are vanes used in the vane axial fan? Amswer: To straighten out
the spiraling motion of the air
◉What will allow a sheave to be used on different diameter shafts?
Amswer: Bushings
◉Where will the classic V-belts (A through E) be used? Amswer:
Medium horsepower applications
◉If you have four belts and one is bad, how many should you replace?
Amswer: 4
◉In a single-duct unit, why is the manual damper left in its initial
position? Amswer: To maintain a constant airflow through the box
, ◉Which design(s) do multiple-path systems use? Amswer: Separate
cold- and warm-air duct distribution systems or separate supply duct to
each zone
◉Why are multi-path, multi-zone systems limited to smaller areas?
Amswer: Because of the multiple runs of single-zone ducts
◉If a cooling demand is reduced in a building, what will the supply
dampers do? Amswer: Begin to close
◉What is one reason for the use of terminal reheat? Amswer: Allow
zone or space control for areas of unequal loading
◉What makes an independent variable air volume (VAV) system truly
independent? Amswer: They can control the maximum and minimum
cfm that can be supplied from the box.
◉How do you prevent carryover into the ductwork while using
atomizing sprays? Amswer: Using an eliminator or filter.
◉When is the use of a return air system generally essential? Amswer:
On larger systems
◉What is the result of a dirty or clogged filter? Amswer: Resistance to
flow and reduced efficiency.
