2. ASHRAE Nomenclature

Try these first

1. 1.

   Define Dry Bulb Temperature (DBT).

   Hint

   Think about what you feel when you check the weather.

2. 2.

   What does Wet Bulb Temperature (WBT) tell us?

   Hint

   Consider the function of a wet thermometer.

3. 3.

   What does Dry Bulb Temperature measure?

   • Actual air temperature
   • Potential evaporative cooling
   • Saturation temperature

   Hint

   Think of the standard thermometer.

4. 4.

   True or False: Dew Point Temperature is where air moisture condenses.

   • True
   • False

   Hint

   Remember when dew forms at night!

5. 5.

   Design a small air conditioning system for a tropical house. Consider DBT, RH, and DPT, and how ASHRAE standards influence your design.

   Hint

   Research the usual humidity levels in tropical climates.

6. 6.

   Critique the application of ASHRAE Standard 55 in an office environment. How could changing parameters impact worker productivity?

   Hint

   Consider why comfort directly influences work performance.
