SCOPE OF GEOTHERMAL ENERGY USAGE FOR AIR CONDITIONING IN BUILDINGS

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 energy is the energy stored in the earth which is received by earth directly from sun and produced by the slow decay of radioactive substances present in the earth’s crust. Further the temperature of earth in depths is almost remains constant in all seasons. So this constant temperature can be utilised for air conditioning in the buildings. This paper presents the possibilities of geothermal energy uses for the air conditioning of buildings. The use of geothermal energy in air conditioning replaces the amount of energy (electricity) required to produce the heat. Use of this energy also minimises the production of greenhouse gases.
