Abstract
Desalination stands out as a prominent method for obtaining fresh water from saltwater sources. The focus of this study revolves around a dehumidifier-dehumidifier system within a closed air-open water desalination framework, exploring two distinct modes: one without integration with solar collectors and the other incorporating solar collectors.Optimal conditions emerged with a fresh water circulation rate of 3 L/min and an incoming salt water flow rate of 1 L/min, resulting in a commendable maximum recovery ratio of 5.33%. Subsequently, in these optimal operating conditions, photovoltaic-thermal (PVT) panels were introduced to the desalination system, yielding insightful results. The output gain ratio (GOR), indicating the efficiency of converting heat to water evaporation, was 0.78 without connecting panels and 0.48 when panels were integrated. With panels connected, the desalination system achieved a peak fresh water production of 2.04 L/hr. Notably, the humidifier tower exhibited an impressive efficiency of 97%, while the dehumidifier tower operated at 40%. The solar collectors contributed significantly, meeting approximately 10% of the system's heating requirements and satisfying 7.3% of its electrical needs. The findings underscore the viability of integrating solar technology into desalination systems, showcasing not only increased fresh water output but also a noteworthy reduction in reliance on conventional energy sources. This innovative approach aligns with the global pursuit of sustainable and efficient water management solutions.
