Why is a refrigerant system dehydrated?

• A. To cool the refrigerant
• B. To prevent compressor failure
• C. To remove the water and moisture
• D. To improve efficiency

Answer: (C)

A refrigerant system is dehydrated primarily to remove water and moisture. The presence of water in a refrigeration system can lead to several serious issues. Water can react with refrigerants and lubricant oils, forming acids that can corrode metal components and damage the system over time. Additionally, moisture can lead to the formation of ice within the system, which can obstruct the flow of refrigerant and disrupt the system's operation.

By ensuring that the system is dehydrated, technicians help maintain the integrity of the refrigerant, protect the compressor from potential damage, and ensure reliable system operation. This process is essential for the longevity and effectiveness of the refrigeration system, making it a critical step in installation, maintenance, and repair.
