| Abstract | This study designs an engineering and economical system for the exploitation of low-enthalpy geothermal energy from the Albian aquifer in heating greenhouses for agricultural production in southern Algeria, specifically for tomato production. The system was designed and evaluated using a computer model that delivers 60°C water at a flow rate of 130–150 l/s. Results show that greenhouse temperatures ranging from 12°C to 15°C can be maintained even at sub-zero temperatures. Economical aspects reveal that geothermal heating can reduce energy costs by as much as 60% compared to conventional systems. The study concludes that geothermal power is a technically and financially suitable, sustainable choice for greenhouse farming in arid regions. |
