What can moisture in a refrigeration system cause?

Moisture in a refrigeration system can lead to compressor failure due to the formation of acid and ice within the system. When moisture comes into contact with refrigerant and oil, it can react to form acids which damage the internal components of the compressor over time. Additionally, moisture can freeze and create ice blockages in the expansion valve or other components, which in turn can cause the compressor to work harder than it should, leading to overheating and potential failure.

Understanding the destructive effects of moisture highlights the importance of maintaining proper system integrity and ensuring that only dry, clean refrigerants are used in the system to ensure longevity and reliability of the compressor and the entire refrigeration system.
