Geothermal (or Geo-exchange) is a type of HVAC System (Heating, Venting, and Air-Conditioning).The earth absorbs almost 50% of all solar energy & remains a nearly constant temperature of 10°C (50°F) depending on geographic location. Working with an underground loop system, a geothermal unit utilizes this constant temperature to exchange energy between the building and the earth as needed for heating and cooling. Geothermal is the most efficient Airconditioning system because the ground temperature stays stable and has no regard for the above ground ambient temperature. A geothermal heat pump simply takes advantage of this low temperature energy source and pumps it up to a usable level to cool/heat the building. Geothermal Heat Pumps draw energy out of the ground which stays relatively constant year round. According to the Environmental Protection Agency , geothermal heat pumps can reduce energy consumption—and corresponding emissions—up to 44% compared to air source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment. The biggest benefit of GSHPs is that they use 25%–50% less electricity than conventional heating or cooling systems . Although geothermal energy is not the sole renewable energy solution, it can play a significant role in helping to meet the heating, cooling, and energy needs of communities across the India. The advantages of geothermal system are more pronounced in larger installations & institutions.
