Abstract

Pri projektiranju stavb je potrebno zadostiti zahtevam prehoda vodne pare v gradbeni konstrukciji, da le ta ne bo prekomerno vplival na prenos toplote in trajnost gradbene konstrukcije. V magistrski nalogi smo predstavili obstoječe raziskave, standarde in pravilnike v povezane s prehajanjem vodne pare in kondenzacijo vodne pare v lahkih gradbenih elementih. Prikazano je vrednotenje kondenzacije vodne pare ter parametri, ki vplivajo na kondenzacijo vodne pare v lahkih gradbenih elementih. Razvili smo metodo korekcijskih faktorjev, s katero tridimenzionalni difuzijski prenos vodne pare obravnavamo kot enodimenzionalni. Metodo smo implementirali v program za inženirsko vrednotenje difuzije vodne pare z Glaserjevim diagramom, ki smo ga uporabili za določitev higrotermalnih lastnosti gradbene konstrukcije. Rezultate smo primerjali z rezultati izračunov, v katerih so bile uporabljene upornosti prehoda vodne pare določene na drugačne načine. Za konec smo predstavili vpliv toplotnih mostov na kondenzacijo vodne pare v lahkih gradbenih elementih.

Secondary title: Modelling of water vapour transmission in modular insulating building elements with water vapour impermeable boundary surfaces
Secondary abstract: When designing buildings, it is necessary to meet the requirements of the water vapour transmission in the building structure so that it does not affect its heat transfer and durability. In this master thesis, we have presented existing research, standards, and rules related to water vapour transmission and condensation in lightweight building elements, the evaluation of water vapour condensation, and the parameters that influence water vapour condensation in lightweight building elements. We have developed a correction factor method to treat three-dimensional diffusive water vapour transmission as one-dimensional. The developed method was implemented in an engineering evaluation application for water vapour diffusion with Glaser diagrams, which was used to determine the hygrothermal properties of the building structure. The results were compared with calculations using resistances of water vapour transmittance determined by other methods. Finally, the influence of thermal bridges on water vapour condensation in lightweight building elements is presented.
