This research designed and built a demountable prototype of a multi-stage solar still coupled to a novel concentrated heat pipe solar collector to produce fresh water from seawater on a small scale, and whose objective was to evaluate the performance of the distiller through its productivity; as well as evaluating the quality of fresh water intended for human consumption. To improve the productivity of the desalination system, an extended copper surface was designed to make the heat transfer in the base or first stage of the still more efficient. To study the effect of the extended surface on productivity, the investigation was conducted in two scenarios: with an extended surface and without an extended surface. The experimental tests were conducted all the month of March of the present in the roof of the pavilion W of the University of Lima (12°05'04“S; 76°50'16“W). For the recording of solar irradiation and temperatures, an automatic system equipped with sensors, a step 7 software and a Siemens PLC model S7-1200 were used. Additionally, a multiparameter equipment was used for manual measurement of total dissolved solids (TDS), electrical conductivity, salinity, and pH. A productivity of 7.32 kg / m2 / day and a thermal efficiency of 14.7% were determined for the still operating with the extended surface. The quality parameters of fresh water obtained from solar distillation from seawater comply with the Regulation of the National Water Quality for Human Consumption (DS N ° 031-2010-SA). Additionally, it has been estimated that the cost of fresh water produced (CPL) in this work is 0.057 $/ L.
