What is the purpose of a dehydrator in a refrigeration system?

The purpose of a dehydrator in a refrigeration system is to remove moisture from the refrigerant. Moisture in the refrigerant can lead to various problems, including corrosion, reduced efficiency, and the formation of ice within the system. By eliminating moisture, the dehydrator helps maintain the integrity of the refrigeration system and ensures that the refrigerant operates effectively and safely.

In a typical refrigeration cycle, moisture can enter through leaks or during the charging process. The dehydrator, often found in the form of a filter-drier, absorbs or traps this moisture, allowing the refrigerant to remain clean and dry. This contributes to the overall reliability and longevity of the refrigeration system, preventing issues that could lead to costly repairs or system failure.
