6.2. Nomenclature

Try these first

1. 1.

   Name one type of natural refrigerant.

   Hint

   Think of refrigerants derived from natural sources.

2. 2.

   What does ASHRAE stand for?

   Hint

   Consider the organization that sets standards for HVAC.

3. 3.

   Which of the following is a natural refrigerant?

   • R-134a
   • CO₂
   • R-22

   Hint

   Recall the examples of natural refrigerants discussed.

4. 4.

   True or False: Synthetic refrigerants typically have higher ODP.

   • True
   • False

   Hint

   Think about the environmental impact we covered.

5. 5.

   You are tasked with designing an eco-friendly refrigeration system. Consider various refrigerants and justify your selection based on their properties.

   Hint

   Focus on what we discussed about desirable properties and environmental impact.

6. 6.

   Analyze the implications of using R-410A in a refrigeration system in terms of its GWP and alternatives that could be considered.

   Hint

   Refer back to GWP discussions to evaluate its impact.
