Abstract

Plitki geotermalni sustavi grijanja i hlađenja koji opskrbljuju domaćinstva te objekte javne i
privatne namjene, prate značajan porast u proteklom desetljeću. Jedan od razloga naglog
razvoja ovog tipa tehnologije je i energetska politika EU koja zagovara proces
dekarbonizacije za zemlje članice. Trend porasta broja instalacija dizalica topline može se
pratiti i na području Republike Hrvatske, s nešto smanjenim intenzitetom u odnosu na
ostatak Europe. S obzirom da u RH ne postoji odgovorno državno tijelo koje vodi evidenciju
o broju i karakteristikama instaliranih plitkih geotermalnih sustava, u sklopu ovog
diplomskog rada napravljena je početna baza dosad instaliranih sustava. Podaci o lokacijama
i tehničkim parametrima sustava prikupljeni su u suradnji s tvrtkama koje se bave
projektiranjem i postavljanjem bušotinskih izmjenjivača topline. Na priloženoj Google Earth
Pro karti lokacije su približno unesene za sve privatne objekte kako bi se izbjeglo
eksponiranje vlasnika. Inovativnom metodom termogeoloških testova na devet lokacija na
području RH određen je karakterističan optimalni prinos bušotinskih izmjenjivača s obzirom
na tip postavljene konstrukcije. Dobiveni prosjek toplinskog prinosa s odabranih lokacija
poslužio je kao osnova procjene ukupne obnovljive energije iz plitkih geotermalnih izvora
koja se koristi na području RH.

Abstract (english)

In the last decade, there has been a tremendous growth in geothermal and aero-thermal heat
pump market. The reason for this growth is the commitment to highly energy-efficient, lowcarbon
EU economy. Trends in installation of heat pumps in Croatia are similar to global
scale of EU, but somewhat slower. Taking in to consideration that today there is no
government office is in charge of supervision of installed shallow geothermal systems and
obtained heat capacity, this Master's thesis provides data about the existing shallow
geothermal systems. Data about locations and technical parameters of the systems have been
gathered in cooperation with service companies that install the borehole heat exchangers.
The Google Earth Pro chart, which is a part of this Thesis, shows the approximate locations
of privately-owned systems, to maintain anonymity. Using an innovative method of
thermogeological tests, optimal sustainable heat extraction rate was determined on nine
locations in Croatia, with regards to the type of the building The resulting average of the
optimal heat rate from chosen locations was used as a base to assess the sum of renewable
energy from shallow geothermal resources used in Croatia.
