Abstract: (19 Views) |
Today, due to the increasing population and the increasing decrease in non-renewable energy sources and the high level of pollution from fossil fuels, humanity is looking for an alternative to them that can reduce costs as much as possible while preventing atmospheric pollution. Solar and geothermal energies are among the clean and cost-effective sources. In this study, the air conditioning system of a building based on the use of two renewable solar and geothermal energies was simulated using EES software and its exergy and energy dissipation were examined. Based on the calculations, the highest exergy efficiency is related to the cold seasons in January and December. In these seasons, the geothermal system performs better due to the highest temperature difference between the depth of the earth and the ambient temperature. The largest required panel surface area is also related to the cold seasons. Based on the obtained graphs, the highest exergy dissipation occurred in the PV system. Also, the refrigerant flow rate required in the refrigeration cycle is higher for the cold. |
