5.1.4. Dew Point Temperature

Try these first

1. 1.

   What is Dew Point Temperature?

   Hint

   Think of condensation.

2. 2.

   How does high Dew Point Temperature affect comfort?

   Hint

   Consider how sticky weather feels.

3. 3.

   What happens at Dew Point Temperature?

   • Air becomes saturated with moisture
   • Air heats up
   • Moisture evaporates

   Hint

   Consider what happens on a cold glass outside.

4. 4.

   True or False: Low Dew Point Temperature indicates high humidity.

   • True
   • False

   Hint

   Think about what dry air feels like.

5. 5.

   In a HVAC system design, if the outside temperature is 35°C and the desired indoor DPT is 20°C, what would be the considerations for cooling the air?

   Hint

   Consider the interaction of cooling and dehumidification.

6. 6.

   An industrial application requires a maximum DPT of 15°C to avoid mold growth. Given the air temperature is 25°C and RH is measured at 70%, should the system initiate dehumidification?

   Hint

   Use the formula to confirm DPT is above the threshold.
