🔍 Key Concepts

• Effect of overheating on lubricating oil in compressors • How refrigerant normally interacts with lube oil (viscosity, bubbles, miscibility) • Meaning of sludge formation vs. changes in viscosity or cloud point

💭 Think About

• Which option describes a condition that would chemically or thermally break down the oil into deposits, rather than just thinning or mixing it? • Think about what physical signs you would see if sludge is present in a crankcase—would that more likely come from temperature damage or from dissolved refrigerant? • Which choice involves a permanent degradation of the oil, instead of a reversible effect when conditions return to normal?

✅ Before You Answer

• Identify which answer choice involves overheating or burning of the oil • Distinguish between viscosity change and sludge/deposit formation • Recall that cloud/floc point deals with waxy separation at low temperatures, not necessarily crankcase sludge in normal operation
