V magistrskem delu je predstavljena analiza izboljšave prezračevanja z uporabo latentnega hranilnika toplote v sistemu prezračevanja z zračnim sprejemnikom sončne energije. Podan je kratek opis sistema sončne energije kot vira za pridobivanje toplote, pregled sprejemnikov sončne energije in hranilnikov toplote s poudarkom na latentnih hranilnikih toplote. Na eksperimentalnem sistemu so bile izvedene meritve v obdobju ogrevanja, ki so bile osnova za validacijo računalniškega modela latentnega hranilnika toplote, ki ga je razvila skupina raziskovalcev iz Univerze za Tehnologijo v Brnu. S programskim paketom TRNSYS je bila izvedena simulacija delovanja eksperimentalnega sistema v ogrevalni sezoni. Iz dobljenih rezultatov simulacije je bilo analizirano delovanje in učinkovitost prezračevalnega sistema. Ugotovljeno je bilo, da latentni hranilnik toplote poveča povprečno temperaturo zraka za prezračevanje.

Abstract

In master's thesis analysis of ventilation improvement with phase change materials storage in ventilation system with solar collector has been presented. Short description of solar energy system as source of heat generation has been provided. Overview of solar collectors and heat storages with focus on phase change thermal storages has been described. Measurements in heating season were performed on experimental set-up which were the basis for validation of computer model of phase change thermal storage. Computer model was developed by the group of researchers from Brno University of Technology. With program tool TRNSYS simulation of experimental system in heating season were performed. From obtained results of simulation operation and effectiveness of ventilation system were analyzed. It was found out that phase change thermal storage increases average temperature of air for ventilation.
