Abstract

Solar ground source heat pump systems offer asustainable solution that reduces energy consumptionand environmental impact. This study develops anintegrated solar ground source heat pump system,evaluating its exergy and environmental impacts. Resultsshow that the exergy efficiency is 49.16%, with a totalexergy destruction of 111.43 kW. The environmentalimpact is greatest during construction, followed byusage, disposal, and maintenance. This study providesvaluable insights for optimizing renewable energyintegration in building systems and serves as a guide forthe design of similar energy-efficient projects.
