A review of liquid desiccant cooling

Dessicant cooling has the ability to provide efficient indoor humidity and temperature control, while at the same time reducing the electrical energy requirement as compared to conventional vapor compression systems. Unlike other surveys on dessicant cooling, this review focuses on a more detailed coverage of liquid dessicant systems. Physical properties are compared for commonly used liquid dessicants (salt solutions and triethylene glycol). Findings from studies considering dessicant/air contact equipement such as packed towers, finned coils, and solar collector regenerators have been summarized in tables for easy comparison. Key features of these tables include the dessicant material, the influence of design variables on the dehumidifier/regenerator performance, and whether experiments were performed. Finally, system configurations are presented schematically, with additional information listed in tabular form
