5.3. Standard Methods

Try these first

1. 1.

   Name the two types of air-conditioning systems based on purpose.

   Hint

   Think about who the systems serve.

2. 2.

   What does 'psychrometry' study?

   Hint

   It's related to air quality and moisture.

3. 3.

   What do we call systems designed primarily for human comfort?

   • Industrial Systems
   • Comfort Systems
   • Utility Systems

   Hint

   Consider who is affected by these systems.

4. 4.

   True or False: Psychrometry is concerned with the study of air without considering humidity.

   • True
   • False

   Hint

   Think about what psychrometry involves.

5. 5.

   You have a room where the air temperature is 35 degrees Celsius with 20% relative humidity. Estimate the cooling load needed to maintain a comfortable environment of 24 degrees Celsius at 50% relative humidity. Calculate using psychrometric principles.

   Hint

   Focus on both sensible and latent heat calculations.

6. 6.

   A factory has a cooling load estimate of 10,000 BTU/hr during the peak summer period. If internal heat gains are expected due to machinery, how would you adjust your estimates? What factors would you consider?

   Hint

   Remember to consider all sources of heat gain.
