🔍 Key Concepts

• Solubility of refrigerant in oil vs temperature (what happens when you heat or cool it?) • Vapor pressure of refrigerant and how temperature affects it • Physical vs chemical methods of removal (draining vs flushing vs temperature change)

💭 Think About

• Think about whether refrigerant is more likely to stay dissolved in oil when the oil is hot or when it is cold. • Which option would encourage more refrigerant to leave the oil phase and enter the vapor phase where it can be recovered? • Are any of the options likely to damage the system or be considered poor practice in normal refrigerant recovery procedures?

✅ Before You Answer

• Compare how heating vs cooling affects refrigerant coming out of solution from the oil. • Decide whether draining oil alone actually recovers more refrigerant, or just removes oil that still contains refrigerant. • Consider safety and standard practice: would flushing with solvent be a normal recommended recovery method, or does that introduce more contamination and complexity?
