INHR 15031 - Refrigerants and Oils 0.42 CR In this module, the HVAC-R student will learn about refrigerants and oils commonly used in HVAC-R systems. The HVAC-R student will also learn about the identification and classification of refrigerants; the differences between pure and blended refrigerants; the types and properties of oils; the use and testing of oils; and refrigerant retrofits.
Course Learning Outcomes:
- Explain the phase change, and how the refrigeration cycle uses the manipulation of latent heat to create the cooling effect.
- Explain and demonstrate subcooling and superheat.
- Name and understand the function of the main refrigeration components including compressors, condensers, metering devices, evaporators, and control devices.
- Identify different types of components such as compressors and controls.
- Identify and define different refrigerants, and refrigeration oils, their regulation, and how they impact the atmosphere.
- Demonstrate proper refrigerant handling, including evacuation, recharging, and leak checking systems.
- Analyze the differences between small-scale systems, through commercial and industrial refrigeration systems, and their related equipment and controls.
