Description
Summary:Nowadays due to the rising price of the energy, many techniques in all fields are used with the aim to reduce the energy consumption. These techniques can be new or traditional. Probably, in other time, their installation were not profitable. In this sense, the buildings heat installations include components to optimize its consumption. As an example, recently, in the rural Spanish territory, the heat installations use geothermal exchangers in combination with heat pump systems. With this component it is possible to save energy, taking heat from the ground to the installation. The use of heat exchanger could be a disturbance for the ground where it is placed. This work analyze a real case, the effect over the ground of a geothermal installation based on an horizontal heat exchanger. As can be seen in the results achieved, as time goes, the heat obtained of the ground is lower. Then, the efficiency decreases with time.
