The Thermodynamic-Analysis-Derived Structure Optimization on the Solar Thermal Localized Desalination and Water-Treatments
The solar thermal localization (STL) technology is promising and cost-effective for desalination or wastewater treatments, but currently in an insufficient status on its structure optimization. This study emphasized the water-cooled STL (WSTL) system and its step-forward modifications, involving the air-insulated WSTL (AWSTL) system and the vacuum WSTL (VWSTL) system, together with their thermodynamic modeling analysis on energy-water conversions, heat-mass transfers, and energy losses. Results indicated the best-performing VWSTL mode can achieve a freshwater yield as high as 1.503 kg·m−2·h−1 at energy efficiency of 68.0% (the light intensity at 1500 W·m−2 indoor), and that of 4.31 kg·m−2·day−1 at energy efficiency of 47.5% (the 8-h averaged solar light intensity at 769.7 W·m−2 outdoor per-day) whose energy efficiency is exceeded all competitors in open literature. There likely is an improvement space in applying better evaporation materials.
