Excessive moisture being collected in the purge unit of a low-pressure refrigeration system could indicate which probable condition?

Correct Answer: Option B — leaking condenser or chiller tubes

Water accumulating inside the purge unit of a low-pressure refrigeration system typically originates from a breached condenser or chiller tube. Water from the seawater cooling side enters the refrigerant space under differential pressure, mixing with the refrigerant and flooding the purge recovery vessel.
