What effect can moisture have on a refrigeration system?

Moisture is a detrimental factor in refrigeration systems, and its presence can lead to a variety of problems, primarily corrosion and system failures. Water, when introduced into the refrigeration system, often combines with refrigerant oils and other substances, forming acidic compounds that can corrode metal components. This corrosion can lead to leaks and failures in the system, compromising the operational integrity and leading to a possibly costly shutdown for repairs.

Additionally, moisture can freeze inside the system, particularly in the expansion valve or evaporator, creating blockages that impede fluid flow. This blockage can further raise system pressures and lead to compressor damage. Therefore, moisture control is essential to maintain system reliability and efficiency, as well as to prolong the lifespan of the equipment.
