What can water in the refrigeration system cause?

Water in a refrigeration system can lead to significant problems, primarily resulting in valve failure, corrosion of metals, and freeze-up at the metering device.

When water is present in the refrigeration system, it can lead to corrosion of metal components. The water reacts with the refrigerant and other materials, leading to rust and degradation that can significantly reduce the lifespan of the system's components. This corrosion may also cause harmful debris to circulate within the system, potentially leading to blockages.

Additionally, the presence of water can cause freeze-up at the metering device. As the refrigerant expands and cools in the metering device, any water present can freeze, creating a blockage that interrupts the flow of refrigerant and severely affects the cooling efficiency of the system.

Overall, the presence of water negatively impacts the overall reliability and efficiency of a refrigeration system, highlighting the importance of keeping moisture out of the system to ensure optimal performance.
