Question 167Refrigeration/AC - 1st Asst/Chief70% 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 lead to several problematic conditions:
1) Corrosion of system piping - Moisture can cause corrosion of metal components in the refrigeration system, leading to leaks and potential system failure.
2) Hermetic motor burnout - Moisture can infiltrate the hermetically sealed motor, leading to short-circuits and motor burnout.
3) Freezing the expansion valve closed - Moisture can freeze in the expansion valve, blocking refrigerant flow and causing the system to malfunction.
Therefore, the presence of moisture in a refrigeration system can result in all of these adverse effects, making option D the comprehensive and correct answer.
