2.1.6. DPT: Dew Point Temperature

Try these first

1. 1.

   What does DPT stand for?

   Hint

   Think about the relationship between temperature and moisture.

2. 2.

   At what point does condensation begin?

   Hint

   Consider when air becomes saturated.

3. 3.

   What does DPT indicate?

   • Temperature of dry air
   • Humidity level
   • Saturation point for air moisture

   Hint

   Think of saturation in relation to moisture.

4. 4.

   True or False: A higher DPT means the air can hold more moisture.

   • True
   • False

   Hint

   Remember the definition of DPT.

5. 5.

   An HVAC system operates at a temperature of 80°F with a relative humidity of 60%. Calculate the Dew Point Temperature.

   Hint

   Use a psychrometric chart or online calculator for assistance.

6. 6.

   Evaluate how changing room temperature affects DPT. If the temperature rises to 85°F while the RH stays the same, what happens?

   Hint

   Consider how temperature interplays with moisture saturation.
