Kaskadno izkoriščanje geotermalne energije

Bernjak, Primož (author), Poredoš, Alojz (mentor)

V nalogi obravnavamo možnosti kaskadnega izkoriščanja geotermalne energije. Izvedli smo zasnovo tehnične rešitve sistema daljinskega ogrevanja, kjer bi geotermalno energijo v prvi kaskadi izkoriščali za ogrevanje stanovanjskih in poslovnih objektov, v drugi kaskadi pa za ogrevanje rastlinjakov. Na podlagi tega smo izvedli oceno vpliva na okolje v primerjavi s sedanjim stanjem in ekonomsko analizo projekta za različne možnosti vzpostavitve sistema daljinskega ogrevanja, kjer smo kot rezultat določili prodajno ceno toplote za končnega uporabnika. Ugotovili smo, na kakšen način je smiselno vzpostaviti sistem daljinskega ogrevanja, da bi na čim bolj učinkovit način izkoristili geotermalno energijo, ki nam je na voljo v analiziranem kraju, in s tem prebivalcem zmanjšali potrebne stroške za ogrevanje, hkrati pa jim izboljšali udobje, kakovost življenja in kakovost zraka v zimskem času.

• Title: Cascading exploitation of geothermal energy

Abstract

This master thesis deals with possibilities of cascading exploitation of geothermal energy. We have performed a scheme for technical solution of district heating system in which the geothermal energy in the first cascade would be used for heating living areas and business premises and the geothermal energy in the other cascade for heating greenhouses. Based on this, we have performed an evaluation of impact on the environment compared to the present state and an economic analysis of the project for various possibilities of establishing district heating system in which the selling price of heat for the end user was defined as a result. We have found out in which way the establishment of district heat system is sensible in order to exploit the geothermal energy available in the analysed place in the most effective way possible and consequently lower the heating costs for the residents. At the same time, comfort, life and air quality in the winter are improved.
