Answer: The heatless regenerative adsorption dryer achieves the drying effect through "pressure change". Since the air's ability to hold water vapor is inversely proportional to the pressure, a part of the dried air (called regeneration gas) is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then it is allowed to flow through the desiccant layer that needs to be regenerated without air flow (that is, the drying tower that has absorbed enough water vapor). The dry regeneration gas absorbs the moisture in the desiccant and takes it out of the dryer to achieve the purpose of dehumidification and drying.
The heatless regeneration adsorption dryer generally consumes about 15% of the intake air as regeneration compressed air.
