Which method of removing water vapor from a pneumatic system deposits water on the solid surface of solid media?

Refrigerated drying is a method used to remove water vapor from a pneumatic system by cooling the air below its dew point. As the air is cooled, the humidity condenses, resulting in the formation of water droplets. These droplets are then collected and separated from the air stream, effectively reducing the moisture content.

The refrigeration process involves passing compressed air through a heat exchanger, where it is cooled to a temperature low enough for water vapor to condense into liquid water. This condensed water may be deposited on surfaces throughout the drying system, especially on the solid media within the dryer, which is designed to facilitate this phase change and enable efficient moisture removal.

The other methods, while effective in drying processes, do not inherently result in water deposition on solid surfaces in the same manner. For example, low temperature drying generally involves the use of cold air but doesn’t focus on condensation through cooling; adsorption drying relies on materials that absorb water vapor, and filter drying uses physical barriers to capture moisture rather than cooling techniques.
