Abstract

Ulaskom u Europsku uniju, Republika Hrvatska preuzela je obvezu ispunjenja određenih energetskih ciljeva između kojih su i smanjenje stakleničkih plinova te poboljšanje gospodarskih prilika korištenjem obnovljivih izvora energije. Prva konkretna realizacija navedenih ciljeva je puštanje u rad prve geotermalne elektrane Velika Ciglena. Jedna od gospodarskih mogućnosti koje se mogu poboljšati uz iskorištavanje obnovljivih izvora energije je opskrba poljoprivrednih gospodarstava toplinskom energijom povoljne prodajne cijene budući da se veliki udio BDP-a Hrvatske temelji na poljoprivredi. Na temelju karakteristika istražnog lokaliteta Lunjkovec – Kutnjak i planiranog projekta izgradnje elektrane i proizvodnje i distribucije transformiranih oblika energije iz geotermalne energije izrađen je dinamički model iskorištavanja geotermalne energije. Geotermalna energija bi se iskorištavala za grijanje staklenika čije su toplinske potrebe određene na temelju vanjskih temperatura zraka u vremenskom periodu od 1999. do 2013. godine. Grijanje staklenika izvedeno je putem dva termotehnička rješenja: sustava direktnog iskorištavanja geotermalne energije koristeći ventilokonvektore i kaskadnog hibridnog sustava gdje se nakon direktnog iskorištavanja geotermalne vode protok usmjerava na sljedeći sustav direktnog iskorištavanja ventilokonvektorima ili na dizalice topline, ovisno o temperaturi geotermalne vode.

Abstract (english)

By joining the European Union, the Republic of Croatia has undertaken the obligation to fulfill certain energy goals, which include reducing greenhouse gases and improving economic opportunities through the use of renewable energy sources. The first concrete realization of these goals is the commissioning of the first geothermal power plant at Velika Ciglena. One of the economic opportunities that can be improved with the use of renewable energy sources is the supply of farms and greenhouses with heat energy at a reasonable selling price, since a large share of Croatia's GDP is based on agriculture. Based on the characteristics of the Lunjkovec - Kutnjak geothermal field and the planned project for the construction of a geothermal power plant as well as the production and distribution of transformed forms of energy from geothermal energy, a dynamic model of utilization of geothermal energy from the waste heat of geothermal water was created. Geothermal energy could be used to heat greenhouses whose heat needs were determined based on outdoor air temperatures from 1999 to 2013. Greenhouse heating was performed through two thermo-technical solutions: a system of direct use of geothermal energy using a fan coil and a cascade hybrid system where, after the direct use of geothermal water, the flow is directed towards fan-coils or heat pumps, depending on the temperature of geothermal water.
