Exergo-economic assessment and sensitivity analysis of a solar-driven combined cooling, heating and power system with organic Rankine cycle and absorption heat pump

District energy systems based on renewable resources help to reduce greenhouse-gas emissions and fossil-fuel use. Here, a multi-generation system combining cooling, heating, power is realized by employing organic Rankine cycle (ORC) absorption heat pump (AHP) technologies, which enable cascading the utilization of solar heat. The AHP can operate steadily providing heating hot water from thermal geothermal sources. A modelling approach presented evaluate energy, exergy, economic, exergo-economic performance above system. results show that could reach coefficient (COP) between 1.38 2.37 depending mode operation. yearly exergy efficiency tri-generation 56.5% 9.6%, respectively. Compared separate system, simple economic payback time 3.5 years. specific cost electricity produced 0.12 $/kWh, whereas much higher, or 0.31 $/kWh. sensitivity analysis performed shows inlet outlet temperatures together with irradiance have highest impact performance. This study provides new direction cost-effective sources in district systems. • Cascading generate multiple products. Energy, assessment different conditions. Specific estimates multi-products analysis. COP pump: for 2.16 water.
