Infiltration Load Quiz

What does the Infiltration Load (QI) represent?

• The temperature of the air inside a refrigerated space

• The humidity level of the air inside

• The volume of the refrigerated space

• The enthalpy of the air entering a refrigerated space

Which factor is NOT considered when estimating the Infiltration Load?

• Interior Volume of the Space

• Air Changes per day

• External temperature

• Usage Factor

How is the interior volume of a refrigerated space calculated?

• Length + Height + Width

• Length - Height - Width

• Length × Height × Width

• Length / Height / Width

What is the interior volume of a cooler measuring 12 ft by 10 ft by 10 ft?

• 1200 ft³

• 1000 ft³

• 1100 ft³

• 1300 ft³

What is the effect of increasing the volume of a refrigerated room on air changes per day?

• Doubles the air changes

• No effect on air changes

• Decreases the air changes

• Increases the air changes

What is the air change estimation for a room in constant use compared to average usage?

• 50% more

• 100% more

• 75% more

• 25% more

What is the ACD for a 0°F refrigerated box with dimensions 9 ft × 13 ft × 8 ft?

• 10.5

• 15.5

What does the Heat Removed Table compare?

• Latent and Sensible heat values

• Temperature and pressure of air

• Humidity and temperature of water

How is the total infiltration load calculated?

• Volume + ACD + Usage Factor

• Volume - ACD - Usage Factor

• Volume × ACD × Usage Factor

• Volume / ACD / Usage Factor

What is the heat removed per day for a 36°F cold room with outside air at 90°F and 60% RH?
