2.2. Common Psychrometric Processes

Try these first

1. 1.

   What is sensible cooling?

   Hint

   Think about changes in temperature that don't affect humidity.

2. 2.

   Describe what happens during cooling with dehumidification.

   Hint

   Consider the effects on uncomfortable humidity.

3. 3.

   What does sensible cooling involve?

   • Changing temperature and moisture
   • Changing temperature only
   • Changing moisture only

   Hint

   Focus on what remains constant during sensible cooling.

4. 4.

   True or False: Cooling with dehumidification adds moisture to the air.

   • True
   • False

   Hint

   Consider what cooling does to humidity.

5. 5.

   A climate control system is designed for a room where 2 kg of air at 35°C and 60% relative humidity needs to be cooled to 22°C with removal of moisture. Calculate the total energy involved.

   Hint

   Recall how to use the heat transfer equations appropriately.

6. 6.

   A manufacturer needs to create a facility where the air must maintain 50% relative humidity at all temperatures. Explain the psychrometric processes they should implement.

   Hint

   Consider how peak seasons might affect the moisture levels.
