Abstract (Croatian)

U ovom radu prikazan je razvoj stacionarnog simulacijskog modela za kompresijske dizalice topline koje se koriste za zagrijavanje prostora i pripremu potrošne tople vode. Iskustveni model se bazira na polinomima drugog stupnja koji aproksimiraju faktor grijanja i toplinski kapacitet dizalice topline u ovisnosti o temperaturama izvora i ponora topline. Koeficijenti polinoma određuju se pomoću mjerenja provedenih prema normi E\N 14511. Model je programiran u Neutral Model Format (NMF) jeziku i implementiran u IDA Indoor Climate and Energy simulacijsko okruženje. Provedena potvrda valjanosti modela pokazala je odstupanja rezultata simulacije od mjerenih vrijednosti u okviru očekivanja s obzirom na tip simulacijskog modela.

Abstract

A steady-state simulation model is presented in this thesis along with the stages in its development. The model aims to simulate compression heat pumps with electrically driven compressors used for space and domestic hot water heating. This empirical model is based on second order polynomials that are used for approximation of coefficient of performance and heat capacity of the heat pump as functions of source-side and sink-side temperatures. Polynomial coefficients are calculated using test results conducted according to EN 14511. Programming was done in Neutral Model Format (NMF) modeling language and implemented in IDA Indoor Climate and Energy (IDA ICE) simulation environment. Accuracy assessment tests were conducted showing that deviations within expected values are obtained.
