COMPARATIVE STUDY BETWEEN GEOTHERMAL AND SOLAR HVAC SYSTEMS

Many applications depend mainly on heat energy, such as solar and geothermal heat pumps. ‎There is a high increase in the use of applications that depend on renewable energy. The ‎main objective of this project is to study the heating systems and geothermal heat pumps. ‎This study also investigated solar heat pumps and the geothermal efficiency to optimize its ‎strategic plan. A performance factor (COP) was used to assess the efficiency of both ‎geothermal and solar systems. To apply the methodology, a case study was used. The ‎results in the thermal energy system are that solar energy is better and more cost-effective in ‎terms of capital. The revenues for the solar system after 25 years were higher than the ‎revenues for the geothermal system. Furthermore, solar power has a shorter payback time ‎making it superior for a similar life span, so it was clear that the expenditure on solar power ‎was safer than the expenditure on geothermal power.‎‎
