Facilities for testing desiccant materials and geometries of dehumidifiers for solar-regenerated desiccant cooling systems
Four experimental test facilities for characterizing the performance of solid desiccant materials and dehumidifier matrices which have the potential to be used in solar-regenerated desiccant cooling systems are reviewed. The water equilibrium capacity and sorption rates of desiccant materials, depending on their form, can be either measured with a quartz crystal microbalance or a desiccant sorption test facility. Pressure drop, heat- and mass-transfer rates and transient equilibrium dehumidification capacity of a dehumidifier matrices are measured in a desiccant heat and mass transfer test facility. The performance and steady state dehumidification capabilities of prototype dehumidifier components under realistic conditions are measured in a desiccant cyclic test facility. The description of the test apparatus, experimental procedure, measurement errors, and typical results for the four test facilities are presented here. 15 refs., 9 figs., 1 tab.
