20.500.12556/RUL-160346 Določitev toplotnih izgub zalogovnika za ogrevanje in hlajenje objekta Defining the heat losses of a water storage tank for heating and cooling a facility Določitev toplotnih izgub zalogovnika je ključnega pomena pri ocenjevanju učinkovitosti toplotnih sistemov, saj omogoča vpogled v njihovo termično zmogljivost in možnosti izboljšav. V diplomskem delu je predstavljeno področje hranilnikov toplote, njihove pomembne komponente, področje toplotnih izgub in razred energijske učinkovitosti. Obravnava je osredotočena predvsem na uporabo zalogovnika s senzibilnim načinom shranjevanja toplote za ogrevanje in hlajenje. Poleg določitve toplotnih izgub zalogovnika smo dodatno opravili eksperiment, s katerim smo merili dejansko kapaciteto zalogovnika. Toplotne izgube ter njegovo dejansko kapaciteto smo merili na dveh različnih zalogovnikih na za to pripravljenem preizkuševališču, ki ga definira standard. Ugotovili smo, da kakovost in debelina izolacije bistveno vplivata na zmanjšanje toplotnih izgub, kar neposredno prispeva k višji energetski učinkovitosti zalogovnika in njegovemu energijskemu razredu. Ugotovitve so tudi potrdile, da zasnova zalogovnika in način razporeditve notranjih komponent prav tako igrata pomembno vlogo pri določanju dejanske kapacitete. Defining heat losses of a water storage tank is crucial for assessing the efficiency of thermal systems, as it provides an insight into their thermal performance and potential improvements. This thesis presents thermal storage tanks, their key components, heat losses, and energy efficiency classes. It is focused primarily on the use of a water storage tank allowing sensible heat storage for heating and cooling applications. In addition to determining heat losses of the tank, we conducted an experiment to measure the actual capacity of the tank. Heat losses and actual capacity of two different storage tanks were measured at a specially prepared testing facility according to relevant standards. We found that the quality and thickness of insulation significantly reduce heat losses, which directly contributes to higher energy efficiency and a better energy class of the water storage tank. The findings also confirmed that the design of the water storage tank and the arrangement of internal components play important roles in determining its actual capacity. shranjevanja toplote zalogovniki toplotne izgube energijska učinkovitost kapacitete zalogovnikov heat storage water storage tanks heat losses energy efficiency storage tanks capacity true false false [B.
