Experimental study on a humidification and dehumidification desalination system of solar air heater with evacuated tubes

Comparative 4E analysis for solar desalinated water production by utilizing organic fluid and water

“…Then, four scenarios were examined showing that the best scenario had a return of capital by 3.5 years. Li et al [32] designed a humidification-dehumidification (HDH) small-scale pilot model. In this work, a series of several experiments have been accomplished for water desalination according to a new type of solar water desalination.…”

Experimental Study of a Humidification-Dehumidification Seawater Desalination System Combined with the Chimney

“…The experimental demonstration devices validate the feasibility of the SHDHSDS [12][13][14][15][16][17][18][19]. And the literature review indicates that the methods of increasing the freshwater productivity mainly include reasonably increasing the system energy recovery stages [7,14], increasing the temperatures of the air side and the water side [4-7, 10, 11, 13, 16], increasing the fluid mass flow rate [10,11,16], increasing the compactness of the evaporation and condensation devices [4][5][6][7], and increasing the heat exchange area [4][5][6][7].…”

“…Literature Review. Recent studies on the SHDHSDSs mainly focus on the heat transfer enhancement in the evaporators and condensers [4][5][6][7], the configuration and operation parameters analyses [8][9][10][11], and the experimental studies on demonstration systems [12][13][14][15][16][17][18][19]. Sievers and Lienhard analyzed the heat transfer and fluid flow inside the flatplate and finned-pipe condensers using numerical simulations [4,5].…”

“…Gu combined the solar air collector, the solar water heater, and the condenser together to form a new guide-plate-infiltration SHDHSDS and found that the seawater temperature, the inlet air, and the cooling water flow rates had high influence on the freshwater productivity [18]. Li et al found the freshwater productivity could be increased by increasing the collector air outlet temperature and relative humidity under the same air velocity and cooling conditions [19].…”

Experimental and analytical study on productivity augmentation of a novel solar humidification–dehumidification (HDH) system

“…They showed that preheating results in high productivity of about 22 L/day and the total unit cost was about 0.0578 USD/L. Li et al [26] designed a new kind of solar air heater with evacuated tubes for humidification-dehumidification desalination unit. Sharqawy et al [27] proposed an optimal thermal design for humidification-dehumidification systems.…”
