What effect does moisture have if it enters the refrigeration system?

Moisture entering a refrigeration system can lead to the corrosion of components, which is a significant concern in the operation and longevity of the system. When moisture is present, it can react with refrigerants and other materials within the system, leading to the formation of acids. These acids can cause corrosion on metal parts such as the evaporator, condenser, and compressor, leading to leaks, reduced efficiency, and potential system failure.

Moreover, corrosion can create debris that may clog filters and other components, further impeding system performance. Keeping moisture out of the system is critical for maintaining the integrity and reliability of refrigeration equipment, highlighting the significance of proper maintenance and operational practices in preventing moisture ingress.

The other options do not accurately represent the primary impact of moisture on refrigeration systems. For instance, while increased energy consumption might be a secondary effect of reduced efficiency due to corrosion, it is not the direct effect of moisture entering the system.
