What is one consequence of not removing moisture from a refrigeration system?

Not removing moisture from a refrigeration system can lead to corrosion and ice formation. Moisture in a refrigeration system primarily enters through air leaks, improper handling of refrigerants, or via the refrigerant itself. When moisture is present, several problems can occur.

First, moisture can react with the refrigerant, leading to the formation of acids that cause internal corrosion of the system components, such as the evaporator and condenser coils. Over time, this corrosion can lead to significant damage and failure of these components, requiring costly repairs or replacements.

Additionally, the presence of moisture can lead to the formation of ice within the system. This occurs because moisture can freeze at low temperatures, particularly in the evaporator coils. Ice buildup can obstruct the flow of refrigerant, reducing the system's efficiency and potentially causing compressor damage due to lack of lubrication and increased pressure on the compressor.

Therefore, effectively removing moisture is crucial to maintaining the integrity, efficiency, and longevity of a refrigeration system.
