A dehumidifier is the heart of a liquid desiccant cooling system. In these systems, air is dehumidified using liquid desiccants and cooled with heat exchangers and/or evaporative coolers [I]. A Statistical Analysis Software (SAS) regression analysis was performed on experimental data from a packed tower desiccant dehumidifier tested at Texas Tech. The purpose of this analysis was to determine simple functional relationships for the liquid desiccant dehumidifier for use in computer models of liquid desiccant space cooling systems.
