Abstract (Croatian)

Napravljen je numerički model dinamičke simulacije solarnog spremnika za zimski i ljetni režim rada koji uključuje period sa potrošnjom i bez potrošnje PTV-a. Dobiveni rezultati temperaturnog polja koje je izračunato u programu ANSYS Fluent su uspoređeni sa vrijednostima dobivenim proračunom prema normi HRN EN 15316-5:2017 (podjela na više kontrolnih volumena). Napravljena je analiza utjecaja na stupanj efikasnosti pločastog i vakuumskog kolektora u slučajevima kada se u proračun izmjene topline između radne tvari kolektorskog kruga i potrošne vode ulazilo sa vrijednostima PTV-a dobivenim računalnom simulacijom, prema normi i klasičnim termodinamičkim proračunom.

Abstract

A numerical model of a dynamic simulation of a solar storage tank was made, for winter and summer working mode, including a period with and witout consumption of DHW. The results of the temperature field calculated in the ANSYS Fluent program are compared with the values obtained by the calculation according to the HRN EN 15316-5: 2017 norm (division into multiple control volumes). An analysis was made of the impact on the degree of efficiency of the plate and vacuum collectors in cases when the calculation of the heat exchange between the heat transfer fluid and consumable water entered the DHW values obtained by computer simulation, according to the norm and the classical thermodynamic calculation.
