How can water damage occur in refrigeration systems due to high humidity?

High humidity levels can lead to increased condensation in refrigeration systems. As air passes over the evaporator coils, it cools and loses its ability to hold moisture, which then condenses on the coils and surfaces within the refrigeration unit. When the humidity is particularly high, the volume of moisture that condenses can exceed what the system is designed to handle, leading to water pooling or dripping. This excess moisture can contribute to water damage, including corrosion of components, mold growth, or water damage to surrounding areas.

In contrast, reduced airflow can lead to other issues such as poor cooling efficiency but is not a direct cause of water damage due to humidity. Compressor overheating usually relates to mechanical or operational issues rather than humidity directly causing water damage. Refrigerant leakage is a separate issue tied to the refrigerant itself, not the moisture levels in the air affecting the system's condensation process. Therefore, increased condensation is the most relevant factor in the context of water damage caused by high humidity in refrigeration systems.
