What effect does moisture have in a refrigeration system?

Moisture in a refrigeration system can lead to corrosion and system failure, which is why this choice is the correct one. When moisture enters the system, it can combine with refrigerants and oils, forming acids that corrode components such as the compressor, evaporator, and condenser. This corrosion weakens parts, leading to potential failures that can compromise the entire system's functionality.

Moreover, moisture can lead to the formation of ice within the system, blocking refrigerant flow and causing operational inefficiencies. It can also affect the thermal properties of the refrigeration system, reducing its overall performance and lifespan. Therefore, managing moisture is crucial for maintaining a reliable and efficient refrigeration system.
