Izdelava geosond in uporaba različnih injekcijskih mas

Lampič, Marko (author), Vukelič, Željko (mentor)

Uporaba obnovljivih virov energije (OVE) po svetu in Evropi dandanes zelo narašča. Vzroke zato lahko najdemo predvsem v zmanjševanju izpustov toplogrednih plinov, ter zmanjševanju odvisnosti od uvoza energije in energentov. Ena izmed oblik uporabe obnovljivih virov energije je tudi geotermalna energija. Te energije je na Zemlji v izobilju, vendar je njeno izkoriščanje še zelo majhno. Geotermalno energijo se največkrat uporablja za ogrevanje, v zadnjih letih pa lahko beležimo porast izkoriščanja toplote tudi za pridobivanje električne energije. V Zemljini notranjosti se nahaja toplota, ki jo lahko odvzamemo s pomočjo toplotne sonde oz. geosonde. Geosonda je vgrajena v vrtino katero zapolnimo z injekcijsko maso. Takšen sistem ogrevanja in hlajenja stavb je zaprt, saj medij s katerim dovajamo toploto do toplotne črpalke ne pride v stik s kamninami v notranjosti Zemlje.

• Title: Production of downhole heat exchanger and use of different injection masses

Abstract

The use of renewable energy sources (RES) around the world and in Europe is increasing today. The reasons for this can be found primarily in the reduction of greenhouse gas emissions and the reduction of dependence on energy and energy imports. One of the uses of renewable energy is also geothermal energy. This energy is abundant on Earth, but its utilization is still very low. Geothermal energy is mostly used for heating, but in recent years we can see an increase of heat for electricity production. The Earth's interior contains heat that can be removed by means of a downhole heat exchanger. The downhole heat exchanger is built into the well which is filled with injection mass. This system of heating and cooling of buildings is closed system, because the medium by which heat is supplied to the heat pump does not come into contact with rocks inside the Earth.
