摘要: Abstract Considering the drive to develop innovative and sustainable food production systems, this study analyzes a novel renewable energy powered self-sustainable greenhouse. The system is designed based on principles of decentralization within systems sustainability improve security region. greenhouse unit utilizes humidification-dehumidification phenomena using saline groundwater provide optimum growing conditions plants throughout year thus making self-sustaining agriculture possible in arid climates. subsystems integrated proposed include unit, parabolic trough collector, organic Rankine cycle, absorption cooling system, thermal storage. A detailed thermodynamic model developed mass, energy, entropy, exergy balance equations for all components system. comprehensive parametric performed determine performance relationship between different inputs outputs Results illustrate that capable providing year-round essential requirements an efficient environmentally friendly manner. 17.5–27.3 m3/day produced freshwater, 4.3 MW cooling, 1.03 MW electricity gained output ratio about 2.10–3.3 while maintaining temperature humidity level inside
