Experimental validation confirms improved thermal efficiency and productivity in solar desalination systems, highlighting energy recovery.
This paper presents a novel Thermoelectric Distillation System (TEDS), a modified hemispherical solar still designed to address the efficiency limitations of conventional desalination units. The TEDS integrates a parabolic reflector to intensify solar thermal input and a Peltier thermoelectric module that performs a dual function: (i) actively cooling the condensation surface to enhance vapor condensation, and (ii) recovering waste heat from the hot side to preheat the circulating feed water. Experimental validation demonstrates a sustained average temperature differential (?T) of approximately 10.6 ?C, resulting in enhanced performance. Compared with a conventional solar still, the TEDS provides an additional 1.0?1.5 L/day of freshwater, confirming improved thermal efficiency and productivity. The results establish TEDS as an energy-efficient, scalable solution for sustainable, decentralized freshwater production.
