Through this recent simulation, we investigated the effect of different physical parameters on the productivity of the greenhouse still coupled with a cylindro-parabolic solar concentrator and an autonomous photovoltaic generator that prolongs the distillation time during the night. An attempt has been made to determine the various parameters that improve the productivity of the hybrid distiller during the day and at night. We identify new modifications and thermal and electrical storage mechanisms to achieve results, which illustrate the advantage and disadvantage of physical parameters to have a solar-based distillation that lasts 24 hours. This study will be a research opening to increase the productivity of solar distillers. Until we reached the water fill for a long time possible in allweather cases by solar energy.

Various studies have been made to improve the efficiency of the solar still. These studies had devoted to the combination of solar collectors with solar still. This article proposes the use of all forms of solar thermal or photovoltaic energy. In addition, photovoltaic electric storage systems convert them to thermal energy that increases the temperature of a greenhouse solar still. We investigated the possibility of improving the productivity of a greenhouse still and prolong solar distillation overnight. The proposed system is the incorporation of thermal energy produced by a parabolic-cylindrical concentrator, a greenhouse still, and photovoltaic solar energy by panels. The production at 14 pm reaches 110 L/m2 thanks to the various thermal sources made up of the hybrid still. It has better productivity than other distillers. The distillation is extended in the evening thanks to a storage system using electric batteries. The production at 18 pm to 18 L/m2 is reduced at 24 pm to 5 L/m2 in the dark. The accumulated temperature decreases the negative influence of the physical parameters on the production which exceeds 100 L/m2 per day. In the evening, the production is reached 16 L/m2 at 22 pm, which is an advantage compared to other distillers.

“…Electric generation by closed Brayton cycle (BC) using supercritical carbon dioxide (sCO 2 ) as a working fluid has gained considerable attention in recent years 29 because of the potential for higher cycle efficiency and simple design than the steam RC. Generally, sCO 2 ‐BC operates between low pressure of 8000 kPa, which is close to the critical point (7.39 MPa and 31°C), and high pressures up to 25 000 kPa 30 . sCO 2 ‐BC ensures operating at high temperatures than RC and attains better performance than other closed BCs such as helium‐BC, providing appealing working conditions for variable temperature ranges 31 .…”

The main objective of this study is to investigate the feasibility of a waste heat recovery (WHR) closed Brayton cycle (BC) working with supercritical carbon dioxide (sCO 2). For this aim, an actual WHR steam Rankine cycle (RC) in a cement plant was evaluated thermodynamically. After, a sCO 2-BC was theoretically adapted to the actual WHR system for the performance assessment. Both systems were analyzed comparatively in terms of energy and exergy. According to the results, the sCO 2-BC showed higher performance than the actual steam RC with a net electricity generation of 9363 kW where it was calculated as 8275 kW for the actual cycle. In addition, the energy efficiencies were found to be 27.6% and 24.18% where the exergy efficiencies were calculated as 58.22% and 51.39% for sCO 2-BC and steam RC, respectively. In the following part of the study, the closed BC was examined for different supercritical working fluids, namely, CO 2 , pentafluoroethane (R125), fluoromethane (R41), and sulfur hexafluoride (SF6). Parametrical analyses were conducted to determine the effects of the system parameters such as turbine inlet temperature, compressor inlet temperature, and pressure ratio on the cycle performance. The simulation results of the comparative study showed that, among the supercritical fluids, the CO 2 demonstrated a higher performance for the closed BC with an energy efficiency of 27.9% followed by R41, SF6, and R125. As a result, the utilization of sCO 2-BC for WHR can be sustainably adapted and extended for environmentally friendly energy generation.
