Izbira geotehnoloških parametrov pri izrabi plitve geotermalne energije

Matuš, Rok (author), Vukelič, Željko (mentor)

V današnjem času se vedno pogosteje odločamo za uporabo obnovljivih virov energije, h katerim spada tudi geotermalna energija. Takšno obliko energije imamo na Zemlji v izobilju, izkorišča pa se je zelo malo. Največkrat se geotermalna voda iz globokih vrtin uporablja za ogrevanje, v zadnjih letih pa je v porastu izkoriščanje toplote za proizvodnjo električne energije. Toploto, ki se nahaja v Zemljini notranjosti, lahko odvzamemo s tako imenovano toplotno sondo oz. geosondo. V tem primeru medij ne pride v stik s kamninami v notranjosti Zemlje, saj je sistem zaprt. Toploto vodi preko mešanice glikola in vode do toplotne črpalke, od tu naprej pa v sisteme ogrevanja ali hlajenja stavbe.

Abstract

Nowadays, we are deciding to use more and more renewable energy sources. One of them, is geothermal energy. This form of energy is on Earth in abundance, but the exploits is very little. In majority, geothermal water from deep wells is using for heating. The use of heat for electricity production has increased in recent years. Heat, located in the interior of Earth, can be obtained with so-called downhole heat exchanger. In these case, the medium does not come in contact with the rocks in Earth interior, because this system is closed up. Heat, is leading by suspension of water and glycol into the heat pump, and from here into the system of heating or cooling in the building.
