Özet

Energy efficiency techniques are among the most significant methods for reaching net-zero emissions in the following years. This research paper covers the feasibility and thermodynamic investigation of a combined model that utilizes flue gas heat recovery for a factory application. Here, the applicability of the developed energy conversion method to factory waste heat at 232 °C and the energy and exergy efficiency of this structure in terms of thermodynamics are investigated parametrically and theoretically. This developed study consists of a waste heat recovery cycle, an isobutane fluid Organic Rankine cycle, an ammonia-water coupled fluid absorption cooling system, a PEM electrolysis, and solar PV units. Power, heating, cooling, and hydrogen are among the useful products produced by this plant's integrated, simultaneous operation. From the comprehensive thermodynamic analysis, the developed multigeneration model can generate 56.73 kW of net electricity, 143.8 kW of cooling demand, 360.4 kW of heating demand, and 0.00007213 kg/s of hydrogen rate under the specific working condition. Furthermore, the energetic and exergetic performance indicators of the modeled cycle are found to be 38.83 % and 16.50 %, respectively.
