Wood is a porous material that can be impregnated and have enhanced properties. Two species of hardwood, red oak (Quercus rubra L.) and sugar maple (Acer saccharum Marsh.), were impregnated in a reactor with a microencapsulated phase change material. The objective was to enhance the thermal mass of wood boards used as surface layers for engineered wood flooring manufacturing. Preliminary experiments were conducted on small samples in order to define suitable impregnation parameters, based on the Bethell cycle. Thin wood boards were impregnated with a microencapsulated phase change material dispersed into distilled water. Several cycles of pressure were applied. Heating storage of the impregnated wood boards was determined using a dynamic heat flow meter apparatus method. A latent heat storage of 7.6 J/g over 3 °C was measured for impregnated red oak samples. This corresponds to a heat storage enhancement of 77.0%. Sugar maple was found to be harder to impregnate and thus his thermal enhancement was lower. Impregnated samples were observed by reflective optical microscopy. Microcapsules were found mainly in the large vessels of red oak, forming aggregates. Pull-off tests were conducted on varnished samples to assess the influence of an impregnation on varnish adhesion and no significant influence was revealed. Engineered wood flooring manufactured with impregnated boards such as characterized in this study could store solar energy and thus improve buildings energy efficiency. Although wood is a material with a low-conductivity, the thermal exchange between the PCM and the building air could be good enough as the microcapsules are positioned in the surface layer. Furthermore, flooring is an area with frequent sunrays exposure. Such high thermal mass EWF could lead to energy savings and to an enhancement of occupant’s thermal comfort. This study aimed to characterize the potential of impregnation with MPCM of two wood species in order to make high thermal mass EWF.

“…The experimental data demonstrated that PCM panels helped to decrease peak temperature, reduce temperature fluctuation and increase thermal inertia. Barreneche et al [85] investigated both thermal and acoustical characteristics of SSPCM layers in a building between 4th June 2013 and 4th September 2013. In the measurement, the indoor air temperature was decreased by 3°C for the room with PCMs.…”

Phase change material (PCM) elements in buildings as effective thermal energy storage technologies could decrease indoor temperature swings and lower building cooling/heating loads due to their great latent heat and proper thermal conductivity. Shape-stabilized phase change materials (SSPCMs) attracted interest of many researchers due to their outstanding ability of keeping shape for long-term multiple thermal cycles with no need of encapsulation. A summarize on thermal dynamic characteristic and thermal performance of buildings integrated with SSPCMs is important for us to gain a better understand on their performance and energy saving potential in both active and passive buildings. This study has reviewed applications of SSPCMs embedded in building enclosure in recent ten years (2008-2018). Both numerical and experimental research works on integrating SSPCMs into building envelope components, such as walls, floor, roof and windows, were reviewed, respectively. A thorough conclusion about this review work and appropriate recommendations for further studies were presented at the end of the paper. This review work will help both researchers and engineers to capture up-to-date uses of SSPCMs to achieve energy efficient buildings.

Abstract.The study was carried out to the determine performance of passive wall cooling panels by using Phase Change Materials as a cooling agent. This passive cooling system used cooling agent as natural energy storage without using any HVAC system. Eight full scale passive wall cooling panels were developed with the size 1500 mm (L) x 500 mm (W) x 100 mm (T). The cooling agent such as glycerine were filled in the tube with horizontal and vertical arrangement. The passive wall cooling panels were casting by using foamed concrete with density between 1200 kg/m 3 -1500 kg/m 3 . The passive wall cooling panels were tested in a small house and the differences of indoor and outdoor temperature was recorded. Passive wall cooling panels with glycerine as cooling agent in vertical arrangement showed the best performance with dropped of indoor air temperature within 3°C compared to outdoor air temperature. The lowest indoor air temperature recorded was 25°C from passive wall cooling panels with glycerine in vertical arrangement. From this study, the passive wall cooling system could be applied as it was environmental friendly and less maintenance.
