SUMMARY:

Aware of the global need to ensure access to drinking water and that most of the water on the globe contains salinity levels that make it impossible to consume and use it in the home, we propose, in this work, simulations that allowed us to understand some of the phenomena relevant to the functioning of solar desalinators, mainly aimed at optimizing the water production capacity from conventional equipment to modified equipment. For this, simulation in EMSO software was used, starting from the mathematical modeling of energy balances. Daily productivity results were obtained of 1.5671 L/m² for the conventional model, 1.8604 L/m² for the modified model with low pressure, 1.7416 L/m² for the modified model with a 50W heat source , 1.9646 L/m² for the modified model with a 100W heat source and 2.1970 L/m² for the modified model with a 150W heat source. The results of nanofluids did not fit the proposed model, since the model used in the literature is not, according to what we have seen, capable of describing the phenomena. Furthermore, the results were compared with experimental data from the Northeast region, obtaining 2.7310 L/m² of daily production. The results made it possible to understand the characteristics of the different models regarding heat transfer, as well as it was possible to evaluate the best equipment represented by the model and its cost-benefit ratio. Within these characteristics, the modified model with a 150W heat source was the best fit.
