Characterization Of Solid Desiccant For Dehumidification Applications

Solid desiccant-based dehumidification systems have been considered extensively for separate sensible and latent cooling systems. The performance of overall system heavily depends on the desiccant characteristics. The objective of the current study is to investigate the steady state and transient properties of a solid desiccant systems. Test schemes have been proposed to investigate the performance of desiccants where samples are exposed to various humidity conditions. The moisture adsorption and desorption behaviors have been evaluated and the data has been used to establish moisture adsorption and desorption isotherms at various temperature. Along with steady state performance, transient behavior has been investigated by determining the mass diffusion coefficients at different humidity and temperature conditions. The overall goal of the study is to provide designer the fundamental material characteristics which are important to the operation of a solid desiccant-based equipment.
