Refrigerant Properties


The various properties of refrigerants, an explanation of the terms zeotropes, azeotropes, and near-azeotropes and the difference between them, the thermodynamic, physical and safety properties of common refrigerants.

Upon completion of this module you will understand how to:

1. Define the term refrigerant.
2. Describe common refrigerant requirements
3. List the refrigerants that are in use today
4. Explain the difference between zeotropes, azeotropes, and nearazeotropes.
5. Define the terms bubble point, dew point, fractionation, and glide.
6. List and describe the thermodynamic, physical, and safety properties of several common refrigerants.
7. Explain the relationship between refrigerants and oils.
