Cooling Load Calculations Quiz 1

Which tool is commonly used to perform detailed cooling load calculations?

• Handheld calculator

• HVAC simulation software

• Thermometer

• Anemometer

In the context of cooling load calculations, what does "U-value" represent?

• The thermal resistance of a material

• The overall heat transfer coefficient

• The specific heat capacity

• The rate of air infiltration

What does the acronym "ASHRAE" stand for?

• American Society of Heating, Refrigerating and Air-Conditioning Engineers

• Association of Solar Heating and Refrigeration Engineers

• American Society of Home and Residential Engineers

• Association for Sustainable Heating and Renewable Energy

What is the primary purpose of calculating the cooling load for a building?

• To determine the heating requirements

• To size the air conditioning equipment

• To estimate electricity usage

• To measure indoor air quality

In cooling load calculations, the term "diversity factor" refers to:

• The peak load divided by the total connected load

• The load variation due to different seasons

• The ratio of actual load to estimated load

• The fraction of the total load that is latent heat

What is the typical specific heat capacity of air in BTU/(lb·°F)?

• 0.12

• 0.24

• 1.00

• 1.08

Latent heat gain in a building is primarily due to which of the following?

• Solar radiation

• Air infiltration

• Moisture from occupants

• Electrical appliances

Which of the following is a sensible heat gain component?

• Heat from people

• Heat from lights

• Heat from appliances

• All of the above

Which of the following factors does NOT directly affect the cooling load calculation?

• Occupant activity levels

• Building orientation

• Outdoor temperature

• Building height

What is the unit of measurement commonly used for cooling load in the SI system?

• BTU

• Watts (W)

• Celsius (°C)

• Kilograms (kg)
