Abstract

V magistrskem delu smo želeli pokazati, ali obstaja možnost uporabe visoko–temperaturne toplotne črpalke z namenom izrabe odpadne toplote v postrojenju Leka, d. d., Proizvodnja Lendava. Najpomembnejša parametra, potrebna za to raziskavo, sta vstopna in izstopna temperatura iz visoko–temperaturne toplotne črpalke in delovna snov. V tem primeru je vstopna temperatura visoko–temperaturne toplotne črpalke 60 °C, izstopna temperatura pa 120 °C. Te temperature tudi predstavljajo temperature izhlapevanja in kondenzacije, kar je pomembno za izbiro delovne snovi. Na podlagi preračuna je prikazana analiza faktorja ogrevanja in ekonomske upravičenosti za različne delovne snovi. Najprimernejša se je izkazala delovna snov R1234ze(Z) z faktorom ogrevanja 4,06 in povračilno dobo 55 let.

Secondary title: High temperature heat pump for exploiting heat weast
Secondary abstract: In this thesis the goal was to show if there is a possibility of using a high temperature heat pump for utilizing waste heat at the plant of the company Lek d.d., Production Lendava. The most important parameters required for this research are the inlet and outlet temperature from the high temperature heat pump and the working substance. For this example, the inlet temperature to the high temperature heat pump is 60 °C while the outlet temperature from the high temperature heat pump is 120 °C. These temperatures also represent the evaporation and condensation temperatures, which is important for the selection of the working substance. Based on the calculation the analysis of the COP and the economic viability for different working substances is presented. The working substance R1234ze (Z) with a COP of 4.06 and a payback period of 55 years proved to be the most suitable.
