6.1. Classification

Try these first

1. 1.

   What are the two main types of refrigerants?

   Hint

   Think of substances found in nature versus those that are man-made.

2. 2.

   What does GWP stand for?

   Hint

   Consider its relation to environmental impact.

3. 3.

   What are the two main classifications of refrigerants?

   • Natural and synthetic
   • Solid and liquid
   • Cheap and expensive

   Hint

   Consider how refrigerants are sourced.

4. 4.

   True or False: All refrigerants are synthetic.

   • True
   • False

   Hint

   Think about the definitions provided earlier.

5. 5.

   Calculate the potential GWP impact of using a refrigerant with a GWP of 1000 over 10 years in terms of CO2 equivalents for a system using 1 kg of that refrigerant.

   Hint

   Use the given GWP as a multiplier for the amount of refrigerant.

6. 6.

   A new regulation bans the use of refrigerants with an ODP greater than 0.1. If a refrigerant with an ODP of 0.2 is used in a system, what steps must be taken?

   Hint

   Consider alternative refrigerants listed in the previous studies.
