Question 72Refrigeration/AC - 1st Asst/Chief70% to pass
If the discharge reed valves used in a refrigeration compressor are leaking badly, what statement is true?
AI Explanation
The correct answer is D) the reed valves should be replaced.
If the discharge reed valves in a refrigeration compressor are leaking badly, it indicates that the valves are worn or damaged and need to be replaced. Attempting to regrind or relap the valves (option A) may provide a temporary fix, but it does not address the underlying issue of valve deterioration. The low side pressure will actually be higher than normal (not lower as stated in option B) due to the leakage, and lowering the high-pressure cutout setting (option C) would not resolve the problem and could potentially lead to other issues.
Replacing the faulty discharge reed valves is the appropriate solution to restore the compressor's proper operation and prevent further damage to the system.
