Algeria, with its burgeoning industrial sector, faces a growing need for sustainable and efficient sources of thermal energy. This study explores the potential of parabolic trough systems to address the specific heat requirements of Algerian industries, highlighting the importance of utilizing TRNSYS and EES for a comprehensive simulation and optimization approach. This paper aim to investigate the utilization of parabolic trough technology to meet the specific heat demands of industrial processes in Algeria. Focusing on simultaneous heat and electricity generation, the study employs the combined capabilities of TRNSYS (Transient Systems Simulation Tool) and EES (Engineering Equation Solver) to simulate and optimize a tailored parabolic trough system for sustainable and efficient industrial heat applications. A case study was taken of a factory that processes animal wool at a temperature of treated water. The results obtained were that the heat generated by solar energy can provide water to reach a temperature between 50–90 ℃, and this allows Operating the industrial cycle of the factory well.
