The use of phase change materials (PCMs) for thermal storage in buildings was one of the first applications
studied,toget her with typical storage tanks. An interesting possibility in building application is the
impregnation of PCMs into porous construction materials,such as plasterboard or concrete,to increase
thermal mass. The thermal improvements in a building due to the inclusion of PCMs depend on the climate,
design and orientation of the construction,but also to the amount and type of PCM. Therefore, these
projects require a complete simulation of the thermal behaviour of the designed space in the conditions of
use established a priori.
In this paper a simple methodology for the energetic simulation of buildings including elements with
PCMs using the program TRNSYS is presented and validated. This procedure does not aim a simulation
of the real transfer processes inside the materials with PCM,but to evaluate the influence of walls/ceiling/
floor with PCM in the whole energy balance of a building. The key parameter in the simulations is the
equivalent heat transfer coefficient which has to be determined for each material. Experimental evaluation of the coefficient is presented. The methodology is applied in a building such as a prototype room built with
concrete panels with PCM. |
