Abstract

Namen diplomskega dela je bil izračun izkoristka toplotne črpalke zrak/voda na podlagi spreminjanja zunanje temperature zraka skozi celotno ogrevalno sezono. Izračun v diplomskem delu je narejen na podlagi zunanjih temperatur zraka v mestu Maribor, kjer se je za obdobje 5-ih let izračunala in določila krivulja vsote dnevov s srednjo dnevno temperaturo. Iz krivulje se je nato s pomočjo numeričnih izračunov določila srednja dnevna temperatura za celotno ogrevalno sezono in povprečno grelno število toplotne črpalke. Iz izračunanega povprečnega grelnega števila oz. izkoristka toplotne črpalke so se izračunali celoletni stroški ogrevanja stanovanjskega objekta. Stroški ogrevanja so se določili za tri razrede energetske učinkovitosti objektov. Glede na določeno celoletno porabo toplote objekta v posameznem energetskem razredu so se, za primerjavo stroškov ogrevanja toplotne črpalke, izračunali še stroški celoletnega ogrevanja drugih ogrevalnih sistemov. S primerjavo investicijskih in obratovalnih stroškov različnih ogrevalnih sistemov se je določil tudi vračilni rok posameznih investicij, kjer se je izkazalo, da je toplotna črpalka zrak/voda najbolj ugodna izvedba ogrevalnega sistema zgradb, če je letna poraba ogrevalne toplote dovolj velika.

Secondary title:	THE DETERMINATION OF THE COEFFICIENT OF PERFORMANCE AND THE COST OF HEATING WITH A HEAT PUMP AIR/WATER
Secondary abstract:	The aim of the present thesis was to calculate the efficiency of the air/water heat pump based on changes in ambient air temperature during the entire heating season. The calculation in the thesis was made on the basis of ambient air temperature in the city of Maribor, where a curve of the sum of days with daily mean temperature was calculated and determined for a period of 5 years. From this curve, and with the help of numerical calculations, the daily mean temperature for the entire heating season was determined, as well as the average coefficient of performance of the heat pump. The annual heating costs for a housing were calculated based on the average coefficient of performance or the efficiency of the heat pump. The heating costs for three categories of energy efficiency of buildings were determined. To compare the costs of heating with a heat pump, the annual heating costs for other heating systems were calculated depending on a housing's determined annual heat consumption in each of the categories. By comparing the investment costs and the operating costs of different heating systems the return of investment for individual investments was also set, highlighting the air/water heat pump as the most favourable heating system implementation in buildings, if the annual consumption of heat for heating purposes is high enough.
