INFLUENCE OF PHASE CHANGE MATERIALS ON THERMAL STABILITY IN ATTIC ROOMS

Stejskalova, K.; Ostry, M.
Abstract:
In summer, building interiors are often overheated. It is common situation especially for buildings with structures from lightweight materials (e.g. attic rooms). One of the ways to solve the excess heat removal from the interior during the summer months is integration of some phase change material (PCM) into building structures. PCMs are capable of storage latent heat at normal indoor air temperatures. In this paper, a comparison of thermal stability in two geometrically identical attic rooms is made. The difference between these two attic rooms is the composition of their building structures, as one of them contains PCM and the other does not. The thermal stability assessment is based on measuring indoor air temperatures in both attic rooms under the same climatic conditions. The measurement of individual temperatures was continuous for several days. In the conclusion, the course of temperatures in both interiors and in the exterior is evaluated and a graphic comparison of measured results is performed.
