Numerical Investigation on Auxiliary Heat Sources for Horizontal Ground Heat Exchangers

Human interference with the Earth’s climate cannot be ignored any longer. Renewable energy sources need utmost attention in all sectors. For buildings, geothermal for heating, cooling, and domestic hot water is a sustainable solution. Horizontal ground heat exchangers (HGHE) demonstrate promising results low installation costs. Research focused on increasing their thermal performances by structural improvements proprieties improvements, little research using auxiliary to increase performances. A numerical model an HGHE was established investigate effects of HGHE. The that transfer into increases overall temperature at end heating season 138.50% compared no from sources. freezing period decreased approximately 24.74% having heated basement, 40.20% transferring solar panels, 62.88% both difference between undisturbed 3.45 °C. resulted 0.92
