Energy and water management in photovoltaic and MOF-303-based hybrid systems

Metal-organic frameworks (MOF), as an innovative material, have been tested in various systems and devices for water production. However, no studies have been encountered regarding water production using hot air generated by photovoltaic systems. In this study, the effect of air heated via photovoltaic panels on water production was investigated by delivering it to the surface of MOF material. Different irradiation levels (900 W/m?, 1000 W/m?, and 1100 W/m?), fan speeds (1.0 m/s, 1.6 m/s), MOF quantities (100 g, 200 g), and MOF box dimensions (0.06190 m?, 0.07712 m?) were tested. According to the results, for each irradiation level, the thickness of the MOF-303 material increased when the surface area was reduced, leading to an extended water extraction duration. Additionally, it was observed that higher air velocities resulted in a longer water extraction time. This phenomenon is attributed to the reduction in the temperature of the air delivered to the MOF-303 surface at higher air velocities, which is initially heated via the photovoltaic panel. Consequently, the water production duration increased. Based on the experimental data, the amount of water produced ranged between 0.30 mL and 1.17 mL.
