Exergoeconomic and Environmental Evaluation of a Ground Source Heat Pump System for Reducing the Fossil Fuel Dependence: A Case Study in Rome

By 2050, the European Commission aims to achieve a 90% reduction in greenhouse gas emissions within construction sector due new targets set for gases by Commission. One of most effective solutions mitigating environmental impact buildings is integrate renewable-energy systems such as air-to-water heat pumps or geothermal pumps. Several works literature investigated advantages pumps, particularly ground source specific contexts. Furthermore, evaluation can encompass not only energy considerations but also exergetic aspects, and this paper makes significant contribution latter. The study presented here applies exergy analysis pump system that interconnected with photo-voltaic solar collector building located Rome. Feasibility assessments were conducted. It evident efficiency obtained much lower than efficiency. demonstrates higher producing high-temperature thermal power compared constant dead state at relatively low temperatures. Following pump, adiabatic mixer exhibits second highest efficiency, trailed two exchangers. Compared conventional plant case, money saved EUR 16,772 per year, translating Payback Period 23 years. average annual fossil fuel estimated 26.2 metric tons CO2.
