I. Refrigerated Air Dryer:
A refrigerated air dryer (also known as a cold dryer) uses physical principles to reduce the moisture in compressed air below the dew point, expelling water from the air to obtain drier air. Simply put, it cools the air to separate water. However, limited by the freezing point of water, the theoretical dew point temperature of a refrigerated dryer can approach 0°C but cannot reach 0°C. After treatment by a refrigerated dryer, the pressure dew point typically ranges from 2–10°C. The water removal efficiency reaches 99.44%.
Compressed air flows into the evaporator, where it exchanges heat with the refrigerant through the evaporator's heat exchange function. The heat in the compressed air is carried away by the refrigerant, rapidly cooling the compressed air. The moisture in the humid air reaches saturation temperature and quickly condenses. The condensed water forms droplets, which are separated, and the water is discharged through the automatic drain valve.
The pressure dew point of air treated by a refrigerated dryer can reach 2°C. Air at this dew point generally meets the moisture content requirements of most equipment. If a lower dew point is needed, an adsorption dryer must be used.
