6.1.3. Latent Heating

Try these first

1. 1.

   What is latent heating?

   Hint

   Think about moisture changes in air.

2. 2.

   What does Dew Point Temperature indicate?

   Hint

   Relate this to humidity levels.

3. 3.

   What does latent heating involve?

   • Temperature change
   • Phase change without temperature change
   • Increasing air pressure

   Hint

   Focus on the concept of phase changes.

4. 4.

   True or False: Dew Point Temperature is when air is completely dry.

   • True
   • False

   Hint

   Consider what happens at saturation.

5. 5.

   If an air conditioning unit needs to remove 1,000 kg of humid air, how much energy must it expend if the humidity is reduced by half?

   Hint

   Look into the formulas connecting mass, latent heat, and humidity changes.

6. 6.

   Design a system that maintains a constant Dew Point Temperature in a clean room. What factors must be considered?

   Hint

   Think about how each variable contributes to the control of conditions.
