Resumo
In the present work was constructed and modeling a solar distiller water pilot installation. The
equipment was installed in the Institute of Chemistry of the Federal University of Goiás, in Goiânia
(16 ° 40’S 49 ° 15’W). The choice of solar distiller is due to the high incidence of solar irradiation
in Brazil. With the data of solar irradiation and using the environmental model it was determined
that 20º would be the best angle for the coverage inclination of the equipment. Besides that, using
the temperature data of water and coverage, each hour from 7 to 18, and the energy balance,
proposed by Dunkle in 1961, the heat transfer coefficients, heat transfer, mass transfer rates, and
the efficiency of the distiller were calculated. We conclude that the heat transfer coefficient of
evaporation and its corresponding rate were higher than the respective convection, the production
of distilled water in winter and summer were 0.31 and 1.51 kgm-2day- 1, respectively, and the
efficiency of the distiller was 5,4% in the winter and 41,33% in the summer. The water obtained
meets the parameters of the Brazilian Pharmacopoeia and can be used in chemical laboratories in
substitution to that obtained in the electric distillers.
