Abstract

In remote areas, the use of solar distillation systems and atmospheric water extraction generators is proposed as a suitable option for water supply. Among solar distillation systems, the multi-effect vertical distillation (VMED) type is considered an optimal choice due to advantages such as high-quality freshwater production, optimal performance, simple design, and portability. Additionally, the use of thermoelectric coolers in these systems, as an innovative approach, increases the overall efficiency by effectively dissipating excess heat and enhancing the performance of the distillation units. In this research, energy and exergy analysis was conducted on multi-effect vertical distillation (VMED) systems equipped with hybrid solar panels and advanced coolers. The main goal was to improve thermal efficiency and reduce energy losses through the integration of renewable and modern technologies. In this system, hybrid solar panels (PVT) serve as the source of both thermal and electrical energy, while advanced thermoelectric coolers play a key role in reducing excess temperature and increasing panel productivity. The results show that this technology combination leads to reduced thermal losses, increased energy quality, and improved exergy performance in the distillation system. This method is particularly recommended for regions with limited water resources and abundant solar energy, offering significant economic and environmental benefits.
