Question 1.
What is the definition of Dry Bulb Temperature (DBT)?
Show hintHide hint
Think about how temperature is typically measured.
Question 2.
What does WBT indicate in psychrometry?
Show hintHide hint
It relates to how moisture influences temperature readings.
3Question 3.
What does DBT measure?
- Humidity
- Air temperature
- Air pressure
Show hintHide hint
Think of how a standard thermometer functions.
4Question 4.
Is Wet Bulb Temperature influenced by moisture content in the air?
- True
- False
Show hintHide hint
Consider what happens when water evaporates.
Question 5.
You are tasked with designing a cooling system for a small library. Given that the outdoor air temperature is 35°C with 60% humidity, what DBT and WBT would the system need to maintain for optimal comfort inside?
Show hintHide hint
Use the psychrometric chart to visualize the relationship between DBT and WBT.
Question 6.
Consider a scenario where you must analyze the cooling load for a commercial kitchen. Outline the steps you would take using system modeling methods and equations.
Show hintHide hint
Remember to consider both the thermal envelope and internal sources of heat gain.
