20.500.12556/DKUM-63453 Izbira postroja za soproizvodnjo toplote in električne energije v podjetju Lentherm-invest d.o.o. Layout selection of the powerplant for cogeneration of heat and electricity in the company Lentherm-invest d.o.o. V diplomski nalogi je opisana ekonomska upravičenost vlaganja v soproizvodno enoto za podjetje Lentherm-invest d.o.o. V začetku diplomskega dela smo prikazali toplotne potrebe v podjetju, nato še potrebe po električni energiji. Na podlagi porabe toplote smo izbrali najprimernejšo soproizvodno enoto. Naredili smo primerjavo dveh soproizvodnih enot, ki sta se razlikovali po velikosti. Izračunali smo količino proizvedene toplote in električne energije iz vsake enote ter primanjkljaj, ki ga bomo pokrivali s starim kotlom na ELKO. Z izračunanjem neto sedanje vrednosti investicije smo preverili, s katero investicijo imamo v dvajsetih letih boljši donos. Izkazalo se je, da je v primeru porabe podjetja Lentherm-invest d.o.o. bolje izbrati zmogljivejšo soproizvodno enoto »indop 370M«, s katero bi v življenjski dobi enote privarčevali 1.860.020 €. This thesis describes the economic viability of investing in cogeneration unit for the company Lentherm-invest d.o.o. At the beginning of the thesis, we presented the thermal needs of the enterprise, then the demand for electricity. Based on the consumption of heat, we chose the most appropriate cogeneration unit. We made a comparison of two cogeneration units which differ in size. We calculated the quantity of heat and power from each unit and the deficit which is covered with an old boiler ELKO. By calculating the net present value of the investment, we checked which investment in the twenties produces better return. It turns out that in the case of consumption in the company Lentherm-invest d.o.o. it is better to choose a more powerful cogeneration unit "Indop 370M" which would save € 1.860.020 in the life cycle of the unit.
