摘要：
The integration of solar water desalination utilizing humidification dehumidification (HDH) techniques with a cooling system (CS) and hot air flow rate was investigated experimentally during Sept and Oct. 2020 under Egypt's Suez governorate's climate located at 29.9669 degrees N, 32.5499 degrees E. The system performance at various air flow rates, water basin height of the daily production was tested. A porous activated carbon tube (PACT) was utilized as a humidifier where the relative humidity reaches 100%, and the cooling system was used as a dehumidifier. The results revealed that increasing water height (H-w) enhances freshwater productivity. The highest distillate yield occurred at water height 3 cm, increasing 13.75% and 5.5% compared with water height 1 cm and 2 cm, respectively. The optimal hot air flowrate is 0.01156 kg/s with an increase of 100%, 38.46%, 15.9%, and 34.5% compared with 0.0057, 0.0086, 0.0144, and 0.0173 kg/s, respectively. The maximum freshwater production is 6.12 kg/day. The energy and exergy efficiencies and gain output ratio (GOR) are 26.73% and 1.57%, and 1.24, respectively. Economic analysis showed that the cost of 1 L of fresh water is 0.01386 USD. (C) 2022 Elsevier Ltd. All rights reserved.
