HVAC BOMA 501 EXAM
1. Dual Duct System: A system in which hot air and cold air are supplied by separate ducts and mixed at each
controlled space to provide the desired supply air temperature. This method consumes a great deal of energy.
2. Muiltizone System: an a/c system in which the zone control is obtained by mixing hot and cold air at the
unit in response to a room thermostat
3. Load Calulations: take the sensible heat and the latent heat into consideration
4. which of the following does not provide sensible heat gain?: Heat from cooking or hot
baths (latent heat has to do with moisture)
5. Which of the following is the way that solar radiation disperses in a building?-
: Transmitted directly to the interior of the building, absorbs by glass, reflected into the building
6. outside air may get into the air conditioning spaces by...: infiltration through the walls,
infiltration through the swinging doors, air induced by replaced exhaust
7. In commercial buildings heat generated by lights does not seriously affect the
1/6
,control of the heating system: false
8. the human body's feeling of well being depends upon....: The body's metabolism
9. which of the following natural laws has the greatest bearing on the science
of air conditioning?: Boyles' Law, Charles' Law, Dalton's Law
10. Why is a pitch pocket commonly used?: To protect the piping and seal the roof from refrigeration
lines passing through it
11. Which of the following is an evaporative type condenser and what governs
its cooling?: a cooling tower governed by web bulb temperature
12. on an evaporative condenser what is the purpose of the eliminator: to separate
the moisture carry over
13. specific heat of a substance: the amount of heat necessary to raise the temperature of one pound of
a substance one degree Fahrenheit
2/6
, 14. Latent Heat: the amount of heat necessary to change a liquid to a vapor with no change in temperature
15. The difference between a pump, a fan and a compressor is....: pumps pump liquid,
fans and compressors pump air
16. Which of the following checks should be made of a blower-drive?: Check the blower
belts for cracks and wear, check the motor bearings for wear, check the blower bearings for wear
17. Which of the following is a good rule to follow when checking air filters?: air
filters should be of the size and type recommended by the equipment manufacturer
3/6
