A5 – HVAC Variety – Grader Comments

• 
  Students have done a very good job in the numeric parameter part. All teams were able to find an extensive range of parameters for their systems.
  
• 
  The system descriptions show that students have difficulties understanding how each piece of the equipments in the systems work together. A good way to understand them is to look at the circulating path of working fluid (medium such as air, water or refrigerant that delivers heating and cooling). For this purpose, I have created a summary table for the major systems presented in class. Hopefully this will be helpful to students in developing the decision matrix for the next assignment.
