“…Another technique that has been presenting advances and improvements for the desalination of saline waters is Humidification-Dehumidification (HDH) coupled with different types of renewable energies and cooling and desalination technologies [157][158][159]. Recent studies reported an increase in the water production rate from 10.8 to 32.1 Kg/m 2 /day thanks to the use of hygroscopic solutions such as kaolin [160].…”

Thermal desalination is yet a reliable technology in the treatment of brackish water and seawater; however, its demanding high energy requirements have lagged it compared to other non-thermal technologies such as reverse osmosis. This review provides an outline of the development and trends of the three most commercially used thermal or phase change technologies worldwide: Multi Effect Distillation (MED), Multi Stage Flash (MSF), and Vapor Compression Distillation (VCD). First, state of water stress suffered by regions with little fresh water availability and existing desalination technologies that could become an alternative solution are shown. The most recent studies published for each commercial thermal technology are presented, focusing on optimizing the desalination process, improving efficiencies, and reducing energy demands. Then, an overview of the use of renewable energy and its potential for integration into both commercial and non-commercial desalination systems is shown. Finally, research trends and their orientation towards hybridization of technologies and use of renewable energies as a relevant alternative to the current problems of brackish water desalination are discussed. This reflective and updated review will help researchers to have a detailed state of the art of the subject and to have a starting point for their research, since current advances and trends on thermal desalination are shown.

“…This classification was based on the research methodology to achieve an appropriate balance among previously implemented studies. The authors introduced and discussed the major research points, important research findings, and future work for each category, while Lawal and Qasem 62 classified the HDH desalination systems depending on the renewable and low‐grade energy sources such as waste energy of photovoltaic/thermal (PV/T), refrigerators and heat pumps, and thermal power plants.…”

Desalination process using humidification–dehumidification technique: A detailed review

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.

“…More than 60% of the energy produced by fossil fuels is dissipated as wasted heat, from which more than 50% is low-grade heat energy with temperatures lying lower than 275 • C [1][2][3]. Low-grade heat is also available from green energy resources like geothermal [4] and solar energy [5]; hence, utilizing low-temperature thermal energy leads to an increased thermal efficiency [6] and in the percentage of green energy [7]. Buildings, primarily for HVAC, consume about 40% of the world's primary energy and are responsible for about one-third of global CO2 emissions [8].…”

Direct Analytical Modeling for Optimal, On-Design Performance of Ejector for Simulating Heat-Driven Systems

This paper describes an ejector model for the prediction of on-design performance under available conditions. This is a direct method of calculating the optimal ejector performance (entrainment ratio or ER) without the need for iterative methods, which have been conventionally used. The values of three ejector efficiencies used to account for losses in the ejector are calculated by using a systematic approach (by employing CFD analysis) rather than the hit and trial method. Both experimental and analytical data from literature are used to validate the presented analytical model with good agreement for on-design performance. R245fa working fluid has been used for low-grade heat applications, and Engineering Equation Solver (EES) has been employed for simulating the proposed model. The presented model is suitable for integration with any thermal system model and its optimization because of its direct, non-iterative methodology. This model is a non-dimensional model and therefore requires no geometrical dimensions to be able to calculate ejector performance. The model has been validated against various experimental results, and the model is employed to generate the ejector performance curves for R245fa working fluid. In addition, system simulation results of the ejector refrigeration system (ERS) and combined cooling and power (CCP) system have been produced by using the proposed analytical model.
