Pravilna zasnova konstrukcijskih sklopov je ključnega pomena v gradbeništvu, saj tako omogočimo trajnost in dolgo življenjsko dobo stavbe ob sočasni energijski učinkovitosti stavbe, zmanjšamo rabo energije, preprečujemo rast mikroorganizmov, uravnavamo temperature in vlažnost prostorov ter tako vplivamo na kakovost notranjega okolja. V Sloveniji se zaradi podnebnih lastnosti pri načrtovanju konstrukcijskih sklopov osredotočamo še posebej na zimske pogoje. Zaradi tega so konstrukcijski sklopi prilagojeni zimskim razmeram z izbiro primernih materialov, pozicijo parne zapore ali ovire, ki se mora nahajati na notranji oziroma toplejši strani toplotno­izolacijskega sloja, in primerno debelino toplotne izolacije. V sklopu diplomske naloge nas je zanimalo, kako hlajenje prostorov v toplem delu leta vpliva na higrotermalni odziv konstrukcijskih sklopov, ki so bili pretežno zasnovani za zimske pogoje delovanja. Tako smo za štiri konstrukcijske sklope zunanjih sten in štiri konstrukcijske sklope poševnih streh s programskim orodjem Ubakus analizirali površinske temperature in difuzijo vodne pare skozi konstrukcijski sklop. Pri določanju robnih pogojev smo se osredotočili na hlajene stanovanjske in industrijske objekte, ki imajo v prostorih predvideno visoko vlažnost. Ugotovili smo, da med konstrukcijskimi sklopi ne prihaja do večjih razlik med temperaturami notranjih površin in pripadajočih relativnih vlažnostih, vendar se razlike pojavijo pri nastali količini kondenzata in njegovem računskem času izsuševanja. Kondenzacija je v vseh primerih nastala v ravnini parne ovire ali zapore, zaradi njene napačne pozicije v konstrukcijskem sklopu. Rezultati analize so nam pokazali pomebnost prilagoditve zasnove konstrukcijskih sklopov na predviden namen uporabe prostora.

• Title: Specificities in designing construction details for cooled spaces with high humidity : graduation thesis no.: 447/B-GR

Abstract

The correct design of the building envelope is vital in the construction industry, as it enables the durability and long life of the building at the same time as the energy efficiency of the building, reduces energy consumption, prevents the growth of microorganisms, regulates the temperature and humidity of the premises and thus affects the quality of the internal environment. In Slovenia, due to the climatic characteristics, we focus primarily on winter conditions when designing building envelopes. For this reason, the structural assemblies are adapted to winter conditions by choosing suitable materials, the position of the vapour barrier, which must be located on the inner or warmer side of the thermal insulation layer and the appropriate thickness of the thermal insulation. As part of the bachelor thesis, we were interested in how the cooling of rooms in the warm part of the year affects the hygrothermal response of construction details mainly designed for winter operating conditions. With the Ubakus software tool, we analysed four external walls and four pitched roofs. We were interested in their surface temperature, relative humidity of the surface and diffusion of water vapour through the construction detail. When determining the boundary conditions, we focused on cooled residential and industrial buildings, which are expected to have high humidity. We found no significant differences between the temperatures of the internal surfaces and the relative humidity between the cases. However, the amount of formed condensate and its calculated drying time differed. This appeared in the vapour barrier layer in all cases, due to its incorrect position in the construction. The analysis results showed us the importance of adapting the design of structural assemblies for the intended use of the space.
