Energetic, Exergetic, Economic and Environmental (4E) Assessment of a Residential Micro-CHP System: A Case Study

In this study, energetic, exergetic, economic and environmental (4E) assessment of a micro-cogeneration system implemented in multi-family building with 137 flats Konya is conducted. Although industrial CHP applications are prevalent Turkey, the first residential use reported thoroughly analysed communication. Thermodynamic analyses showed that micro-CHP was capable reaching 87% cycle efficiency 70 kWe electrical 115 kWt thermal power, respectively. Moreover, II. Law analysis revealed inefficiencies across such high temperature heat exchanger had lowest exergy 63.7% which part requiring improvement. The could generate $22.10/month return per flat payback period found to be 5.48 years. Lastly, indicated how environmentally friendly argued has prevented more CO2 emissions winter than summer due operating at full capacity. findings support potential elucidate specific conclusion for practice Turkey.
