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 a mechanical failure of the valves. The only proper remedy in this situation is to replace the faulty reed valves, as attempting to regrind or relap them would not address the underlying problem. Leaking reed valves will cause a loss of system efficiency and performance, resulting in the low-side pressure being below normal. Adjusting the high-pressure cut-out setting would not fix the leaking valves and could potentially lead to further system damage. Therefore, the appropriate action is to replace the damaged discharge reed valves.
