6.3. Desirable Properties

Try these first

1. 1.

   Why is low toxicity important for refrigerants?

   Hint

   Think about what might happen if a refrigerant leaks.

2. 2.

   What is the significance of having a low boiling point?

   Hint

   Consider how the refrigerator works.

3. 3.

   What is a desirable characteristic of refrigerants?

   • High toxicity
   • Low toxicity
   • High flammability

   Hint

   Think about safety in refrigeration.

4. 4.

   True or False: All refrigerants have a high Global Warming Potential.

   • True
   • False

   Hint

   Consider current environmental standards.

5. 5.

   Evaluate the significance of choosing a refrigerant with both low toxicity and high latent heat of vaporization for a new commercial refrigerator design. How would disregarding these factors affect the system?

   Hint

   Think about user safety and operational efficiency.

6. 6.

   Analyze a scenario where two refrigerants are competing for application in a food preservation system—one with high flammability, the other with low GWP but high cost. Discuss the decision factors a company should consider.

   Hint

   Consider the long-term impacts on both finance and safety.
