Freshwater resources are in short supply on a global scale, and existing Atmospheric Water Generation (AWG) systems encounter limitations when it comes to generating sufficient water in regions with low relative humidity. To address this challenge, an innovative AWG system employing molecular sieve desiccant has been constructed and empirically examined in ambient conditions. To achieve a high desiccant material regeneration temperature, a 4.86 m2 both ends open evacuated tube collector solar air heater is integrated. The system’s performance is assessed through energy, exergy, and economic evaluations. With an average atmospheric humidity ratio of 6.93 g/kgdry air, this developed system daily generates 3.18 L fresh water at a nominal cost of $ 0.11/L. The system exhibits energy and exergy efficiencies of 8.84% and 5.49%, respectively. Importantly, water quality tests have confirmed the safety of the generated water for its consumption.
