© 2018 Author(s). This research presents the experimental and numerical results of a humidification dehumidification (HDH) unit driven by solar energy. The HDH unit is based in a CAOW water-heated configuration. The water is heated using solar thermal flat collectors. The desalination unit is located in the Renewable Energy Laboratory (LER) of the Universidad Técnica Federico Santa Maria (33°02'22.4"S 71°29'09.1"W) in Chile. The first section of the study is focused in the design of the solar HDH unit. The experimental facility has been instrumented and several operation parameters may be measured. Also, several variables may be adjusted to attempt finding an optimal performance. The modeling of the HDH unit is reviewed in the second section. The numerical model has been developed using Engineering Equation Solver (EES). The performance of the HDH unit is evaluated using mass and energy balances, and mass and heat transfer equations. Three loops are studied: water, air, and solar collector loop.
