Abstract

In the present scenario a very large portion of energy is used for the air conditioning of the buildings which is the wastage of energy as it is required for cooling in summer and for heating in winters. So it is desired that we must use the renewable sources of energy for this purpose and geothermal energy may be one of the suitable energy source. Geothermal (or Geo-exchange) is a type of HVAC System (Heating, Venting, and Air-conditioning).The earth absorbs almost 50% of all solar energy and 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 Air-conditioning system because the ground temperature stays stable and has no regard for the above ground ambient temperature. A geothermal heat exchanger simply takes advantage of this low temperature energy source and sends it up to a usable level to cool the building. Geothermal Heat Exchanger draws energy out of the ground which stays relatively constant year round. This is typically an arrangement of pipes with selected piping material and loop design, buried in the ground. Soil temperature at a certain depth, adequate piping material, configuration and performance of the installed system evaluated experimentally. The temperature gradient of 15oC to 25oC on average has been achieved from the developed working model.
