Continuous excessive moisture collection in the purge unit of a low-pressure refrigeration system could indicate what condition?

In a low-pressure refrigeration system, continuous excessive moisture collection in the purge unit typically indicates a leak in the condenser or chiller barrel tubes. When there is a leak in these components, refrigerant can escape, leading to an inability to maintain proper internal pressure. As the system struggles to keep pressure, moisture from the environment can enter, resulting in the accumulation of water in the purge unit.

The purge unit is designed to remove non-condensable gases and moisture from the system; however, if there is a significant leak, the moisture ingress becomes more pronounced, causing the purge unit to collect more water than usual. This scenario highlights the importance of maintaining the integrity of the refrigeration system to prevent moisture contamination, which can lead to operational inefficiencies and compromise overall performance.

Understanding this context reinforces the significance of regular system checks to identify and rectify leaks, thereby preserving system functionality and refrigerant containment.
