14 - How does introducing air-conditioned and filtered air
at a positive pressure into a building help building
comfort? - Answer-It causes the outward escape of air,
limiting infiltration.
1 - What is the relationship between thermal comfort and
metabolic heat? - Answer-Thermal comfort exists when
the temperature and relative humidity of a persons
environment permit the person to lose, without conscious
effort, metabolic heat at the same rate he or she produces
it.
2 - What occupant activity level is chosen when engineers
design an air-conditioning system? - Answer-average and
peak activity levels
3 - What is the rate of exchange of fresh air for return air
based on in an air-conditioning system? - Answer-The rate
of exchange of fresh air for returned air is based on the
,2|Page
quantity of fresh air required for each building occupant
over the course of time.
4- Define heat - Answer-Heat is a form of energy which
cannot be destroyed only transformed or moved.
Heat is added to conditioned air in the winter and removed
in the summer. No shit.
5 - What happens to the rate of heat transfer if the
difference in temperature increases? - Answer-the rate of
heat transfer Increases if the difference in temperature
increases
6 - What are three methods in which heat is transferred? -
Answer-Convection
Conduction
Radiation
7 - Define conduction - Answer-The direct transfer of heat
from one body to another.

Define connvection - Answer-The transfer of heat using a
substance
Define radiation - Answer-Heat that an object throws off to
its surroundings.
8 - Define sensible heat - Answer-A measure of the
internal heat of a substance.
No change in state or physical property.
9 - Define latent heat - Answer-The energy that is used or
released during the change in state.
10 - Define relative humidity - Answer-The amount of
water vapor held in the air
11 - Does moist air have more or less density than dry air?
- Answer-Moist air has less mass than dry air and is less
dense than dry air.

12 - What is the atmospheric pressure of air at sea level? -
Answer-14.7 psi
13 - Explain Charles' law: - Answer-Charles law explains
why gases expand when heated and contract when
cooled.

air conditioning-system is based on the period of time
covered and the number of building: - Answer-Occupants
2 - All of the 3 following are methods of heat - Answer-
Radiation
Convection
Conduction
NOT Reduction
3 - Which heat load source is most likely to affect all zones
of a building? - Answer-Lighting equipment
