6.1.2. Sensible Cooling

Try these first

1. 1.

   Define sensible cooling in your own words.

   Hint

   Think about what happens to temperature and humidity when air is cooled.

2. 2.

   What does a psychrometric chart help us visualize?

   Hint

   Consider what characteristics of air are represented on this chart.

3. 3.

   Sensible cooling involves:

   • A) Increasing temperature and humidity
   • B) Decreasing temperature without affecting humidity
   • C) Only affecting humidity
   • D) Increasing both temperature and humidity

   Hint

   Think about the process of cooling in HVAC systems.

4. 4.

   True or False: Sensible cooling can also lead to dehumidification.

   • True
   • False

   Hint

   Recall the definitions of these processes.

5. 5.

   An HVAC technician needs to cool an area from 35°C with 60% RH to a comfortable 23°C. Discuss how the technician would maintain humidity while achieving the desired cooling. What methods might they use?

   Hint

   Consider how different HVAC systems can be optimized for specific heating and cooling applications.

6. 6.

   Explain how changes in outdoor temperature and humidity can affect the performance of sensible cooling systems in indoor environments.

   Hint

   Think about the interplay between indoor and outdoor environmental factors.
