questions and answers 2025
BOMI - answer Air Handling, Water Treatment & Plumbing System
Chapter 1 - answer Human Comfort
Review Quiz 1 - answer
1 - The rate of exchange of fresh air for returned air in an 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
4 - To compensate for heat gain from office equipment in modern office building, air-
conditioning systems have been designed to offset how many watts per square foot? -
answer 1 to 3 Watts per square foot.
5 - The leftover heat in a building from the day before is the: - answer Pull-down load
,6 - What exists when the temperature and relative humidity of a person's environment
permit the person to lose metabolic heat at the same rate he or she produces it? - answer
Thermal comfort
7 - Why is it most important to air-condition with sedentary people? - answer They think
about their comfort more
8 - How is sensible heat measured? - answer Dry-bulb thermometer
9 - What type of heat is released or used during a change of state between solid, liquid, and
gas? - answer Latent heat
10 - Which of the following affects the amount of water vapor the atmosphere can hold? -
answer Air temperature
11 - Which of the following is true about mechanical refrigeration cycle air flows? - answer
Air flows from higher pressure to lower pressure
12 - Boyle's law states: - answer As Pressure goes up, volume goes down.
13 - Maintaining temperature and ___Blank___ have a direct impact on maintaining human
comfort. - answer Humidity
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.
Chapter 1 Key Concept - answer
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 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.
14 - Explain Boyle's law - answer Boyle's law states that a constant temperature, as the
volume increases, the pressure decreases.
15 - How does the human body regulate temperature? - answer Sweating when
overheating too cool down.
16 - What system produces the most heat in a building? - answer Zoning HVAC system?
Maybe look into this one.
17 - What are the four main categories of internal heat loads? - answer People Heat Load
Lighting Heat Load
Equipment Heat Load
System Heat Load
