“…Similarly, Xie et al [19] support this by examining the behaviour of PCMs exposed to hot and cold airflow when in contact with building exteriors. Another empirical study reports that a reduction in energy consumption of 48.5% and 44% in both summer and winter could be achieved via PCM being placed inside holes in bricks [20]. Other studies have come to similar conclusions that confirm the potential benefits of using PCMs [21][22][23][24][25].…”

The consequences of extreme energy consumption are seen both in the energy and environmental crisis. Subsequently, researchers are attempting to find methods to address this issue. Building envelopes and insulation materials are elements that can effectively influence consumption through their passive effect on thermal comfort levels. Strategies pertaining to this that rely on both, advanced and traditional materials, have been able to show good potential. However, the technical complexity of using such strategies can be impeded from the perspective of developing countries. With the aim of creating effective low-cost feasible insulations through using methods of minimal intricacies, the potentials of simple amalgamation of materials is empirically investigated in this study. In this context, closed-cell rigid Polyurethane (PU) foam is used as a base to hold phase change materials (PCMs) to create two PU/PCM panels, of different PCM content. The thermal performance of the panels is experimentally examined and compared, with hot-arid climates prevailing in developing countries in mind. Results revealed that panels containing PCMs were able to perform more effectively in comparison with regular PU foam panels, and, that increasing the amount of PCM has also shown to be advantageous in this regard.

Palmitic acid (PA), nano silicon dioxide (nano SiO 2 ), and graphene nanoplatelets (GNPs) were fabricated to composite phase change materials (PCMs) for thermal energy storage. PA acted as PCM, nano SiO 2 was used as supporting material. GNP as thermal conductivity promoter was added to modify composite PCM. Nano SiO 2 has good adsorption property and can adsorb liquid PCM to prevent leakage. Leakage measurement indicated that PA maximum content in composite PCM is 70 wt%. Chemical and crystal structures, and microstructure of composite PCM were tested by Fourier transformation infrared spectroscope, X-ray diffractometer and scanning electronic microscope, which showed that the raw materials are well mixed by physical action. Differential scanning calorimeter result presented that composite PCM possess phase change temperature at about 60 C and latent heat of 128.42 kJ/ kg. Thermogravimetric analyzer and thermal cycle experiment showed that composite PCM have outstanding thermal stability and durability. Thermal conductivity apparatus measurement results indicated that thermal conductivity of composite PCM with 5 wt% GNP is 1.65 times that of composite PCM without GNP. Therefore, this composite PCM are potential materials for thermal energy storage.
