The geothermal is one that takes advantage del calor interno de la Tierra, bien mediante la instalación de intercambiadores de calor en el interior de la misma, ( energía geotérmica de baja y muy baja temperatura ; entre 30º y 90º), o mediante el aprovechamiento directo de dicho calor en estaciones de generación eléctrica, ( energía geotérmica de alta y media temperatura ; más de 90º). La energía geotérmica empleada en el abastecimiento directo de energía en edificios siempre es a baja o muy baja temperatura, y permite satisfacer sin ningún problema y de forma eficiente y económica las exigencias actuales en calefacción y refrigeración inside the thermal conditioning pool and spa, as well as production hot water for domestic use. These facilities need only cover the cost of electric heat pumps and circulation from the installation, and if the thermal conditioning system is by air flow, electrical energy consumed in the corresponding drive fans.
The cost of installing geothermal in a home usually represents the double of a conventional gas (without take into account any subsidies that may be obtained, as in the Community of Madrid are up to 30% of the total budget of the facility), but operating costs as low and above the long-term savings that are obtained by energy self-sufficiency inexhaustible source of heat than justify the installation of a geothermal heat pump , taking into account that energy is increasingly expensive under reduced its offer in contrast to the growing demand for it.
On the other hand, geothermal energy can be extracted from virtually any ground, (either in a superficial or deep underground), and although the installation is ideal in climates of high temperature range (where the air pumps reduce their performance) can be used in any geographical location with excellent results. Geothermal energy production is between 2 and 4 times the electricity consumed, with yields off the electrical resistance of between 200 to 400%. Also, allows energy savings of up to 70% in heating and up to 50% on air on traditional systems of thermal conditioning .
In construction sector, recruitment is done through buried horizontal collectors, geothermal and foundation probes are connected to geothermal heat pump will be doing the transfer of power to the internal distribution system construction. In further comments see a real example of a geothermal power plant in one of the projects currently being developed MBQ Group in order to reduce energy dependence of the buildings and contribute to the improvement of the environment and lower energy expenditure of our customers.
