Moisture in a refrigeration system can cause which of the following conditions?
AI Explanation
The correct answer is D) all of the above.
Moisture in a refrigeration system can cause:
1) Corrosion of system piping: Moisture can lead to corrosion of metal components in the refrigeration system, including the piping.
2) Freezing the expansion valve closed: Moisture can freeze at the expansion valve, causing it to close and restrict refrigerant flow.
3) Hermetic motor burnout: Moisture can damage the hermetic compressor motor, leading to premature failure.
Therefore, the presence of moisture in a refrigeration system can lead to all of the conditions listed in the answer choices.
