Thermal conductivity calculation method: porous structures

Pavlenko Anatoliy, Cheilytko Andrii O., Ilin Sergii, Belokon Yevgen

Journal of New Technologies in Environmental Science

2019

Vol. 3, nr 4

194--205

The article describes the transfer of thermal energy through porous bodies with closed and open porosity. The semi-empirical equation for finding the effective coefficient of thermal conductivity of bodies with a porous structure is derived. The equation of finding the thermal permeability of the porous material and the geometric characteristics of the porous structure are presented.

Computer simulation of heating properties in wall partition with built-in elements that imitate thermal bridges

Tokarski Daniel, Żukiewicz-Sobczak Wioletta, Chodyka Marta, Grudniewski Tomasz, Nitychoruk Jerzy Antoni, Tomaszewski Robert

Czasopismo Inżynierii Lądowej, Środowiska i Architektury / Journal of Civil Engineering, Environment and Architecture

The article aimed at presenting of the design assumptions of the wall partition built anda results of computer simulation of thermal properties in a heterogeneous wall partition in THERM. Display of the isotherms' distribution, heat flux vectors and temperature distribution in the area of thermal bridges and beyond. The tested partition on the basis of which simulations were created, was equipped with elements imitating thermal bridges, used in construction, to show their influence on the thermal properties of building structures. Thermal bridges can take the form of linear and point bridges. The example described in the article concerns the problem of thermal bridges occurring in wall partitions. The simulation is a preliminary pilot action before the start of non-invasive tests, ie measurement and calculation of the heat transfer coefficient, thermovision measurements on the surface of the barrier.

Uzyskanie standardu pasywnego

Pankanin Mateusz, Szczepański Marcin

2019

R.23, nr 11

Celem artykułu jest ocena budynku mieszkalnego w zabudowie bliźniaczej w świetle obowiązujących przepisów dotyczących energooszczędności oraz analiza czasów i kosztów jego wykonania w dwóch wariantach klasy energetycznej. W ramach analizy wyliczono bilans strat oraz zysków ciepła, na podstawie którego utworzono wskaźniki charakterystyczne. Następnie zaproponowano rozwiązania pozwalające obniżyć te wskaźniki do poziomu dopuszczalnych według obowiązujących i przyszłych przepisów dla budynków jednorodzinnych pasywnych oraz porównano koszty i czasy realizacji budynku tradycyjnego ze zmodernizowanym w kierunku klasy budynku pasywnego.

Time and cost analysis of the possibility of obtaining a passive standard of a building on a selected example. The thesis presents the energy performance of a semi-detached house, located in Białystok, in compilance with “Rozporządzenie Ministra Infrastruktury i Rozwoju z dnia 27 lutego 2015 r.” currently in force. The residential building was evaluated in the light of existing legislation concerning thermal protection of buildings, comparing the demand for suitable energy for heating and ventilation with the value characterizing the passive building. Based on these results, the object in question was found to meet the applicable requirements for thermal parameters of the building envelope partitions, but the object was not to meet the applicable requirements for the above-mentioned energy demand for buildings of this class. The thesis also summarizes solutions allowing to approach requirements in the field of thermal protection of passive buildings. Then cost estimates and line schedules were created for variants before thermal modernization and for all thermal modernization stages carried out.
