In refrigeration maintenance, what does dehydration refer to?

Dehydration in refrigeration maintenance specifically refers to the process of removing moisture from the refrigeration system. Moisture in the system can lead to serious issues such as corrosion, the formation of ice, and decreased efficiency of the refrigerant. When moisture is present, it can mix with refrigerant and create acids that can damage components of the system, such as the compressor and evaporator.

By effectively managing moisture levels, refrigeration technicians ensure that the system operates efficiently and reliably. Dehydration is typically achieved using a device called a dehydrator or a filter-drier, which absorbs moisture and keeps the refrigerant dry, thereby maintaining the integrity and functionality of the refrigeration system.
