Abstract

Kontinuirani porast broja stanovnika i razvoj industrije u zemljama trećeg svijeta rezultiraju većom potražnjom za energijom. S obzirom da mnoge države nemaju vlastite resurse fosilnih goriva ili provode ''zelenu politiku'' postepeno se razvijaju tehnologije iskorištavanja obnovljivih izvora energije. Geotermalna energija ističe se mogućnošću kontinuirane opskrbe krajnjih korisnika. Ipak, mogućnost proizvodnje vruće slojne vode ovisi o hidrogeološkim svojstvima sloja. Bušotinski izmjenjivač topline jedna je od tehnologija koja omogućava toplinsko iskorištavanje niskih do srednje visokih temperatura suhih bušotina. Veliki broj napuštenih bušotina posjeduje takve toplinske karakteristike. S obzirom na varijabilnost cijena fosilnih goriva, revitalizacija takvih bušotina sve je češća praksa. Ovisno o karakteristikama bušotine i sloja, pridobivena toplina koristi se direktno ili u kombinaciji s drugim izvorima energije. Zbog jednostavnosti ugradnje i visoke učinkovitosti, česta je kombinacija bušotinskog izmjenjivača topline s dizalicom topline na površini. Napuštena bušotina Savica-1 ima potencijal za grijanje objekata srednje veličine. Stoga, cilj ovog diplomskog rada je odabir optimalnog sustava bušotinskog izmjenjivača topline kako bi ekstrakcija toplinske energije bila što učinkovitija.

Abstract (english)

Continuous population growth and industrial development in third-world countries result in an increased demand for energy. Given that many countries lack their own fossil fuel resources or implement "green policies," technologies for harnessing renewable energy sources are gradually developing. Geothermal energy stands out because of its ability to continuously supply end-users. However, the possibility of producing hot layer water depends on the hydrogeological properties of the layer. A borehole heat exchanger is one of the technologies that enable thermal utilization of low to medium-high temperatures of dry boreholes. A large number of abandoned boreholes possess such thermal characteristics. Considering the variability of fossil fuel prices, the revitalization of such boreholes is becoming increasingly common. Depending on the characteristics of the borehole and the layer, the obtained heat can be used directly or in combination with other energy sources. Due to the simplicity of installation and high efficiency, the combination of a borehole heat exchanger with a surface heat pump is frequent. The abandoned borehole Savica-1 has the potential to heat medium-sized buildings. Therefore, the aim of this master's thesis is to determine the optimal system of a borehole heat exchanger in order to make the extraction of thermal energy from as efficient as possible.
