Analiza hranilnika toplote z uporabo makro-enkapsuliranih fazno spremenljivih snovi

Nusev, Petar (author), Stritih, Uroš (mentor)

V magistrskem delu smo predstavili teoretične osnove senzibilnih in latentnih hranilnikov toplote, pri čemer smo se podrobneje osredotočili na shranjevanje toplote v makroenkapsularnih fazno spremenljivih snoveh. Zasnovali in izdelali smo prototipni latentni hranilnik toplote s sferičnimi moduli, napolnjenimi s FSS. V eksperimentalnem delu smo izvedli meritve pri konstantnih vstopnih pogojih latentnega hranilnika toplote. Nato smo s programskim orodjem TRANSYS prilagodili numerični model latentnega hranilnika toplote Type 840 na začetne in robne pogoje eksperimentalnega sistema ter ga validirali z rezultati meritev. Z validiranim numeričnim modelom smo izvedli parametrično analizo različnih premerov sferičnih modulov, napolnjenih s fazno spremenljivo snovjo, ki se nahaja v obravnavanem hranilniku toplote.

• Title: Heat storage analysis using macro encapsulated phase change materials

Abstract

In this thesis, sensible and latent storage are described, as well as phase transformation of materials are described. The focus of this work is on the analysis of thermal energy storage devices based on macroencapsulated phase change materials (PCM). A prototype of a latent heat storage system with spherical modules filled with PCM was designed. Several measurements were performed on the experimental system under constant input conditions. With the help of the computer simulation program TRNSYS, a validation of the simulation model of the latent heat storage system Type 840 was carried out with the initial and boundary conditions of the experimental system. Finally, a parameter analysis for different diameters of the spherical modules was carried out using the simulation model.
