Abstract

Neprestani rast energenata uzrokovan sve većom potražnjom te svjetskim krizama dovodi do
stalne potražnje za alternativnim tehnologijama grijanja. Najpoželjniji su obnovljivi izvori
energije zbog neograničenih količina te minimalnih utjecaja na okoliš i zdravlje ljudi. Tema
ovog rada odnosi se na postavljanje simulacijskog modela solarne dizalice topline kako bi se
dobio uvid u ponašanje i učinkovitost sustava solarne dizalice topline pri realnim uvjetima.
Nakon postavljene simulacije napravljena je validacija sustava na stvarnim mjerenjima
mobilne solarne dizalice topline. Prikazana je usporedba rada modela za dva grada s različitim
klimatskim uvjetima. Napravljena je godišnja simulacija s vremenskim korakom od 1 sata.
Simulacijski model je uspoređen s konvencionalnim sustavima grijanja te je dan uvid u
troškove i isplativost ugradnje sustava. Prema simulacijskom modelu za Zagreb sustav se
pokazuje neisplativ u odnosu na ostale izvore grijanja, dok su za Split dobivene vrijednosti
manje godišnje potrošnje u odnosu prema ostalim izvorima. Razlog tome su vrijednosti veće
vrijednosti godišnje ozračenosti.

Abstract (english)

The continuous growth of energy consumption caused by increasing demand and global crises
leads to a constant demand for alternative heating technologies. The most desirable sources of
energy are renewable sources due to their unlimited quantities and minimal impact on the
environment and human health. The topic of present paper concerns the development of the
simulation model of a solar assisted heat pump to gain insight into the behaviour and
efficiency under real conditions. After setting up the simulation, the system was validated
with actual measurements of a mobile solar heat pump. A comparison of the model's
performance was shown for two cities with different climatic conditions. An annual
simulation was made with a time step of 1 hour. The simulation model was compared to
conventional heating systems, and insights into the costs and cost-effectiveness of installing
the system were given. According to the simulation model, the system is not cost-effective
compared to other heating sources for Zagreb, while for Split, lower annual consumption
values were obtained compared to other sources. The reason for this is higher annual radiation
values.
