Enhancement of freshwater production of the seawater greenhouse condenser

Seawater greenhouse (SWGH) is a technology established to overcome issues related open field cultivation in arid areas, such as the high ambient temperature and shortage of freshwater. It adopts humidification-dehumidification concept where evaporated moisture from saline water source condensed produce freshwater within body. Various condenser designs are adopted increase production order meet irrigation demand. The aim this study was experimentally investigate practicality using packed-type direct contact SWGH more at low costs, simple design efficiency, explore impact manipulating six operational variables (inlet air humidifier, mass flowrate inlet dehumidifier dehumidifier) on condensation rate. For purpose, designed manufactured. Sixty-four full factorial experiments were conducted effect variables. Each variable operated two levels (high flowrate), each experiment lasted for 10 min followed by 30-min waiting time. Results showed that varied between 0.257 2.590 L every min. When Minitab statistical software significant contributed maximum production, it found humidifier had greatest influence, humidifier; former negative while latter positive production. response optimizer tool revealed optimal combination maximize when all mode mode. comparison old plastic new proposed can 75.9 times same volume.
