Določitev velikosti vpliva toplotnih mostov na ogrevanje tipične enodružinske hiše : diplomska naloga

Rajković, Samo (author), Košir, Mitja (mentor), Pajek, Luka (co-mentor)

V diplomski nalogi je predstavljena analiza vplivov linijskih transmisijskih izgub najbolj pogostih toplotnih mostov, ki se pojavijo v tipični enodružinski hiši. Za določitev vpliva toplotnih mostov je uporabljena numerična metoda na podlagi izračuna toplotnega toka s pomočjo računalniškega programa UcanPsi in standardov SIST EN ISO 10211 ter SIST EN ISO 13370, del analize ter končni izračun pa temelji na standardu SIST EN ISO 14683. Za tipične predstavnike toplotnih mostov so bili izbrani: stik stene in okna, preboj konstrukcije (balkon) ter stik zunanje stene s tlemi na terenu. Rezultat diplomskega dela sta priloženi preglednici, ki omogočata uporabniku hitro oceno vpliva toplotnega mostu glede na dolžino balkona in površino zasteklitve. Preglednici prikazujeta količnik specifičnih transmisijskih toplotnih izgub (HT) ter deleže izgub, ki jih predstavljajo nesanirani linijski toplotni mostovi (DTM).

• Title: Determining of the impact of thermal bridges on a typical single-family house heat consumption : graduation thesis

Abstract

The thesis describes an analysis of the effects of linear transmission losses of the most common thermal bridges that occur in a typical single-family house. Numerical method for calculating the heat flow using the UcanPsi software in combination with SIST EN ISO 10211 and SIST EN ISO 13370 was used to determine the influence of thermal bridges. Part of analysis and final calculation is based on standard SIST EN ISO 14683. Junction between window and external wall, balcony slab edge and joint between ground floor and external wall were used as typical representatives of the linear thermal bridges. As a result of the thesis there are two spreadsheets attached that might help users to quickly assess the influence of the thermal bridge in relation to the length of the balcony with correlation to the amount of glazing. Spreadsheets represent values of the transmission heat transfer coefficient (HT) and percentage of heat loss by uncontrolled linear thermal bridges (DTM).
