🔍 Key Concepts

• Oil circulation in mechanical refrigeration systems • Effect of oil films on heat-exchanger (evaporator) surfaces • Normal vs abnormal symptoms in compressor and expansion valve operation

💭 Think About

• Think about where excess oil that travels with the refrigerant is most likely to collect in the system and what part of the cycle that is. • Ask yourself: if heat cannot move easily from the space being cooled into the refrigerant, what symptom would you notice in operation? • Consider which options describe a realistic, common consequence of oil carryover versus something that would be relatively rare or extreme.

✅ Before You Answer

• Identify which component (compressor, evaporator, or expansion valve) is most sensitive to an insulating oil coating on its internal surfaces. • Check which choices involve heat transfer performance rather than mechanical damage or corrosion. • Eliminate any option that describes a condition that would not normally result simply from extra oil traveling with the refrigerant.
