Refrigerated Air Dryer – Working Principle Explained
Ease of maintenance and relative cost-effectiveness makes refrigerated air dryers one of the most common types used in industrial applications. Without special requirements such as a minimum dew point refrigerated air dryers are suitable for air-drying applications. Talking about the working principle of refrigerated air dryers, this is based on dehumidifying air by rapidly cooling it, condensing it, and draining off the moisture. Domestic refrigerators or home air-conditioning systems have a very similar operation. Step by step process of Refrigerated air dryers is explained here to help you make a wise buying decision: Step 1 - In a refrigeration unit, warm, moist air enters the dryer, which cools it rapidly to about 3°C (37.4°F). At this temperature, the water vapor in the air condenses into pure water, which collects in a water trap and is fed into discharge lines. The warm, gaseous refrigerant is cooled and regenerated in a condenser. Step 2 - The dry air in the chamber is reheat
