🔍 Key Concepts

• Behavior of refrigerant and lubricating oil inside a compressor crankcase • What happens when pressure or temperature suddenly changes in the crankcase • Difference between dissolved gases/liquids and entrapped (bubbled or mixed) gases/liquids

💭 Think About

• Think about which substance is mainly responsible for visible foaming in the crankcase: is it the oil, the refrigerant, moisture, or air? • Ask yourself: when a compressor starts or stops, what could suddenly change that might cause bubbles or foam to appear in the oil? • Consider which option would create the most violent, rapid bubbling action inside the crankcase.

✅ Before You Answer

• Verify which fluid (refrigerant, moisture, or air) is most likely to be dissolved in the lubricant under normal operating pressure. • Check which event would cause a sudden release of bubbles from the oil, making it look like foam. • Eliminate any answers that involve substances that are normally kept out of the system (like moisture and non‑condensable air).
