Thermal performance and cost analysis of mortars made with PCM and different binders

Abstract

h i g h l i g h t s PCM mortars based in different binders were used to study the thermal behavior. The thermal behavior and cost analyses were evaluated based in Portuguese climate. The PCM mortars reveal higher thermal regulation and lower energy needs. The PCM mortars showed a decrease of the cost related to the energy consumption. a b s t r a c tThe high energetic consumption is one of the biggest concerns of modern society. The incorporation of phase change materials (PCM) in construction materials allows regulates the temperature inside the buildings. The main objective of this study was the characterization of the thermal performance of PCM mortars based in different binders. It was possible to observe that the incorporation of PCM in mortars leads to a decrease of the maximum temperatures, increase of the minimum temperatures, significant lag time delay, reduction of the heating and cooling needs, and consequent decrease of the cost of HVAC systems operation, for all tested seasons.

“…Another point that needs to be emphasized is the determination of the optimum PCM ratio to be used in the construction. In this study, it was observed that as the amount of PCM used increases, the thermal performance of the material increases in accordance with the studies in the literature . It can easily be said that when the amount of PCM is increased, the latent heat capacity of the mixtures increases and thermal conductivity decreases.…”

“…Cunha et al . tested the thermal and mechanical performance of mortars made with PCM and different binders. They also conducted cost analysis based on energy consumption of mortars and energy price in Portugal.…”

Thermal Performance of Mortars Based on Different Binders and Containing a Novel Sustainable Phase Change Material (PCM)

“…Type K thermocouples were used. The described set-up is able to supply important and reliable information on the thermal behavior of the mortars, as previously demonstrated [34,35].…”

“…Type K thermocouples were used. The described set-up is able to supply important and reliable information on the thermal behavior of the mortars, as previously demonstrated [34,35]. The thermal behavior of the produced mortars was tested in a climatic chamber, setting a temperature program representative of each season of the year, in order to study the thermal behavior of the developed mortars in summer, spring, autumn and winter.…”

“…Since the presence of a PCM is expected to positively influence the internal temperature of a room where it is applied [3,11,34], thermal tests were conducted with the aim of evaluating the thermal behavior of mortars with incorporation of PCM. During the tests, all seasons of the year were evaluated, taking as reference the climate recorded in Salento region (South Italy).…”
