A solar collector-cum-regenerator (C/R) concentrates liquid desiccant flowing over its absorber surface by evaporating water using solar thermal energy. It is a key component of a solar liquid desiccant air-cooling system. Simultaneous collection of solar energy and evaporation of water occurs as the solution flows over the absorber surface of the solar C/R. The mass flow rate of the solution over the absorber surface is not constant due to the evaporation of water. This paper discusses the use of a single solution tank for regeneration of liquid desiccants (calcium chloride [CaCl2] and lithium chloride [LiCl] solutions) using a solar C/R. It also presents diurnal and seasonal regeneration performance of a solar C/R of absorber area of 4.0 m2 (43.0 ft2) using experimentally collected data sets for hot and dry, hot and humid, and moderately hot and humid weather conditions of Delhi from 9:00 a.m. to 4:00 p.m. The results obtained will be helpful in the design of a solar C/R for coupling with a liquid desiccant cooling system.
