“…Another research involving hybrid systems realized a combination between a wind tower and a SAH to assist a humidification-dehumidification system used to desalinate water which works in an open-air water cycle [21]. In this way, the use of fans is eliminated, the air flow for SAH being achieved through the wind tower.…”

As conventional fossil fuel systems release toxicants into the atmosphere, humanity is increasingly moving towards sustainability, towards using products that do not cause negative effects on the environment, have a long service life and offer multiple benefits. Solar air heating systems are increasingly used in household applications, even in industrial ones at times. The principle of operation of systems of this type is established on the existence of solar radiance, without this the panels have little or no efficiency at all, so they are limited to sunny periods. One of the methods of increasing the impact and performance of these systems is the realization of hybrid systems that offer several benefits with regard to heating the air in rooms, heating water and ventilating spaces. The meaning of this article is to present a summary of the existing literature, in the sphere of solar hybrid air heating systems, on the methods of improvement and the performance achieved.

Summary The lack of fresh water resources is one of the important reasons obstructing progress all over the world. To overcome this crucial situation, the water desalination system (WDS) is progressed, enhanced, and modified. The desalination plant is mostly powered by nonrenewable energy resources, mainly by fossil fuels that make it an expensive and high‐energy‐consuming technology. Therefore, it is indispensable to depend on renewable energy supplies to drive desalination systems. Recently, the total thermal energy desired to operate the humidification–dehumidification desalination systems can be gained from renewable/sustainable energy resources such as geothermal energy and solar energy. Among the different desalination techniques, the HDH is considered one of the most effective desalination techniques to manage the critical issue of shortage of drinking water. The current paper presents a comprehensive review of diverse types of HDH desalination systems as well as their fundamental components. The present work revealed that the seawater HDH system is a promising technology to produce fresh water, particularly for decentralized demand. The packed bed humidifier is the most utilized type in the HDH water desalination system than other types of humidifiers. Furthermore, the direct dehumidifier enhances the performance of HDH desalination system compared to the indirect one. The present study concludes that the hybrid energy systems have the highest gain output ratio, while the thermal energy systems have the lowest gain output ratio. Water heating with solar energy has a significant enhancement in system productivity compared with solar air heating. The HDH WDS incorporated with heat pump achieves appropriate system productivity and gain output ratio with the lowest cost per liter.

“…In the past decade, the establishment of seawater desalination plants in the world has grown rapidly as a means of increasing water supply in countries with water problems. [4][5][6] Today, due to the feasibility of Reverse Osmosis (RO) desalination systems which are demonstrated with some complex systems, reverse osmosis membranes are the leading technologies for new desalination plants, and they are applied to a variety of saltwater resources using the pretreatment design and a suitable membrane system. [7][8][9][10] RO desalination requires much more energy than a typical treatment of surface water.…”

In this article, smart water-energy management based on an artificial neural network for a photovoltaic-wind system coupled with water pumping and reverse osmosis desalination unit with hydraulic storage is developed. The proposed system was designed to meet freshwater demand for remote areas of Tunisia's south. The authors focus on an artificial neural network-type management strategy, ensuring power-sharing between sources, hydraulic components, and tank storage. The main objective of the management strategy is to deliver and purify as much freshwater as possible by taking advantage of all the energy available according to climatic conditions. A parametric sensitivity algorithm is developed to find the most appropriate neural network architecture. A dynamic simulator for 1 year of operation integrates the energy management of the system is developed. The used water-energy management-based artificial neural network showed good results of power-sharing during a fast time with a correlation coefficient and a coefficient of determination between the actual and estimated values of the three motor pumps electrical power equal to 96% and 98%, respectively. Also, the root mean squared error was acceptable at 0.1476. These results have been proved over a year and can be used by other researchers with a similar system.
