🔍 Key Concepts

• Oil circulation in a refrigeration system and how oil returns to the compressor crankcase • What happens to oil and refrigerant during long, steady running versus short cycling • The purpose and behavior of the suction line and oil separator during operation and after shutdown

💭 Think About

• Think about where the oil physically is while the compressor has been running for a long time. Is most of it in the crankcase or spread throughout the system? • After the compressor stops, what needs to happen so that the level you see in the crankcase sight glass represents the true amount of oil in the system? • Which option explains a condition that makes the sight glass reading most accurate, not just a normal operating process?

✅ Before You Answer

• Which choice specifically mentions oil returning to the crankcase, where you actually check the level? • Ask yourself: does the oil separator normally "fill" as a condition for checking oil, or is its purpose something else? • Consider whether the crankcase heater status would mainly affect refrigerant migration or oil level reading, and whether that matches the question’s timing: "shortly after" stopping after a long run.
