Brick masonry walls with PCM macrocapsules: An experimental approach

Uncertainty propagation and sensitivity analysis of thermo-physical properties of phase change materials (PCM) in the energy demand calculations of a test cell with passive latent thermal storage

“…In this case, PCM is integrated into exterior walls composed of a conventional brick constructive solution. The potential of PCM for smoothing indoor temperature fluctuation and indoor air temperature peaks in these applications has been demonstrated in previous experimental studies such as in those of Castell et al [24] analyzing the thermal behaviour experimental cubicles and those of Vicente et al [25] testing different brick wall specimens with PCM in an experimental dynamic wall simulator. Castell et al [24] also demonstrated the ability of PCM for reducing in 15% cooling energy consumption whereas Izquierdo-Barrientos et al [26], who numerically analyzed the influence of phase change temperature on the reduction of heat transfer through a standard Spanish brick wall, highlighted that some undesired dynamic phenomena can be observed if PCM is integrated into a wall with high thermal inertia.…”

Macroencapsulation and characterization of phase change materials for latent heat thermal energy storage systems

“…The fabricated capsules have been shown to withstand 1000 thermal cycles. Vicente and Silva [31] tested parafin wax in rectangular steel shell in horizontally hollow brick for 8 days. Zhao [32] and Zheng et al [33] have reported an encapsulation technique that uses stainless steel/carbon steel as the shell material.…”

Attenuation of Temperature Fluctuations on an External Surface of the Wall by a Phase Change Material-Activated Layer

“…Generally, PCM can be implemented into an inner part of a wall structure in different forms such as: impregnation of building materials, micro-encapsulation, or as a shape-stabilized thin plate [13]. Almost any construction material like concrete [14], gypsum [15] and ceramic [16] was considered as a matrix for paraffin or fatty…”
