Experiments on Sorption Hysteresis of Desiccant Material

Research output: NRELTechnical Report


Solid desiccant cooling systems take advantage of solar energy for air conditioning. The process involves passing air through a desiccant bed for drying and subsequent evaporative cooling to provide the air conditioning. The desiccant is then regenerated with hot air provided by a gas burner or solar collectors. This performance is limited by the capacity of the desiccant, its sorptionproperties, and the long-term stability of the desiccant material under cyclic operation conditions.
