A solar collector cum regenerator (C/R) is a key component of a liquid desiccant air cooling system that concentrates liquid desiccant flowing over its absorber surface. Simultaneous collection of solar energy and evaporation of water occurs as the solution flows over the absorber surface of the solar C/R being exposed to the ambient air throughout sunshine period. This paper discusses the use of a single solution tank for regeneration of liquid desiccants (LiCl and CaCl2 solutions) using a solar C/R of absorber area 4.0 m2 using experimentally collected data sets in a day (9am up to 4 pm) across seasons.
