4. Mathematical Analysis of Air-Conditioning Systems

Try these first

1. 1.

   Define Dry Bulb Temperature.

   Hint

   Think about how you would measure temperature with a thermometer.

2. 2.

   What does the mass balance principle state?

   Hint

   Consider how closed systems function.

3. 3.

   Which of the following variables represents the ordinary air temperature?

   • Wet Bulb Temperature
   • Dry Bulb Temperature
   • Dew Point

   Hint

   Consider what you measure with a basic thermometer.

4. 4.

   True or False: Mass balance states that mass can be created.

   • True
   • False

   Hint

   Think about how baking ingredients don't disappear.

5. 5.

   Design a simple air-conditioning system with a given room size and required temperature. Calculate both sensible and latent heat loads if provided with specific details.

   Hint

   List out the parameters; you might need to calculate heat gains first.

6. 6.

   Critically evaluate the performance of an HVAC system that fails to maintain specified humidity levels despite achieving target temperatures.

   Hint

   Consider areas for improvement in both cooling and air mixing.
