Question 6Refrigeration/AC - QMED70% to pass
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 the following conditions:
1. Freezing the expansion valve closed: Moisture can freeze and clog the expansion valve, preventing proper refrigerant flow and leading to system issues.
2. Hermetic motor burnout: Moisture can cause corrosion and electrical shorts, leading to the failure of the hermetically sealed compressor motor.
3. Corrosion of system piping: Moisture can lead to the corrosion of metal components within the refrigeration system, including the piping, which can compromise the system's integrity.
Therefore, the presence of moisture in a refrigeration system can result in all of the listed conditions, making option D the correct answer.
