The second law analysis of a humidification-dehumidification desalination system using M-cycle

Humidification-dehumidification desalination (HDD) systems offer a feasible approach for the production of fresh water in inaccessible areas as they can be operational using renewable energy and require little maintenance. Various studies are being carried out to boost system performance. In this paper, an open air HDD is proposed that exploits enhanced evaporation condensation processes by implementing with Maisotsenko cycle (M-cycle). The utilizes solar input heat saline water. A thermodynamic model formulated under steady-state conditions, considering first second law thermodynamics. energetic exergetic performance studied. validated experimental data good agreement found where maximum discrepancy about 6.0 %. Effects different operating conditions on key parameters such Gain Output Ratio (GOR), specific consumption (SEC), exergy destruction, efficiency analyzed. An improvement observed GOR when inlet temperature raised at constant humidity ratio. exhibits better dry environment compared humid environment. analysis shows mass flow rate desalinated 22.3 kg/h, recovery ratio (RR) 0.223, 3, SEC 0.23 kWh/kg 43.21
