Investigation of the impacts of the thickness of the composite material on the temperature regime of energy-saving fencing of the outer wall with closed vertical wind channels

Abstract

The proposes of investigation are the energy-saving facade structures with closed vertical canals, which were analyzed in ANSYS medium with finite elemental technique. An analysis of temperature lag of designed structures with vertical closed canals evidenced that contraction in frost protection material volume from 0.08 m3 to 0.055 m3 per 1 m2 gives rise to significant contraction in the temperature lag of outer shells in case with a heat directing shield up to 24.55%, and in case without a heat directing shield up to 26.9%. An analysis was also made of the heat directing shield influence on the temperature lag of a new structure, which evidenced that in case of the heat directing shield in vertical closed canals, the structure’s efficiency in terms of temperature lag value increases up to 20%, depending on external climate conditions. Since energy saving is the main problem all over the world, the investigation data can be realized in buildings’ design, construction, reconstruction, with a view to save heat release rate. At the same time, the use of the developed structures with a heat-reflecting screen with closed vertical channels leads to an increase in the temperature lag indicator, depending on external climatic conditions, by 8.5-20%.
