“…The papers in the Table 3 [12,19,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] respond to the proposal in a negative way. A. Cipollini states that this method is used in areas where they require a short demand of water [15]. While Delyannis states that the method is appropriate for capacities less than 70 cubic meters per day but if more water is required, they another recommend to use other technology [16].…”

Water is essential for the hotel industry, its disposition is key to ensure the viability of the tourism sector that grows disproportionately day by day plus the scarcity of water in the world, this situation forces hotels to find alternatives to meet the demand for water. One of the preferred alternatives is solar water desalination. The purpose of this paper is to demonstrate through this first literature review whether solar desalination is a viable technique to meet the demand of potable water in a medium-sized hotel in a coastal area. We conducted a review of the literature published between 1987 and 2018, the subject of which is solar HDH desalination. Inclusion and exclusion criteria were formulated and applied to determine the most relevant studies to achieve the purpose of this research. The review found that solar desalination can be feasible to apply in hotels if they have large amounts of land for installation or the demand for water is not large. However, there are more economic methods to desalinate water while at the same time producing more water with similar sizes of facilities. Such results have practical implication for the use of the systems of hotels in general.

“…Various factors influence the packing materials selection such as porosity, water absorbent availability, and cost. Various types of packing were used in the HDH desalination systems such as honeycomb paper, 88,178 pall rings, 152,179 wooden chips, 180 ceramic cubic matrix, 181 wooden slats, 182,183 textile or cotton, 31 metallic structure, 184 thorn trees, 185 and plastic Raschig rings. 186 Further, more types of packing materials are presented in details in Tables 2 to 6. Kabeel et al 93 evaluated experimentally a solar HDHWDS utilizing two types of humidifying packing materials of cellulose paper with 5 mm and 7 mm corrugation height.…”

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.

“…The overall productivity of their system increased with the increase in solar intensity and ambient temperature. Farsad et al [10][11] numerically and thermodynamically analyzed one type of HD solar desalinator and investigated parameters influencing fresh water production cycle. Then, using DoE method, they reexamined the sensitivity of parameters affecting the cycle to optimize and to increase the amount of fresh water production.…”
