TLDR
In this paper, the thermal performance of nano-enhanced phase change material (PCM) was investigated under direct/indirect solar exposure and outdoor experiments, under direct and indirect solar exposure.Abstract:
In this piece of work, an attempt to solve the global energy crisis by presenting advanced thermal energy storage technology was experimentally investigated. To enhance the thermal performance of paraffin wax as phase change material (PCM), nanoparticles (NPs) were utilized at 3% wt. concentration in mono and hybrid form: copper oxide (CuO) NPs, cobalt oxide (Co3O4) NPs, and CuO@Co3O4 nanocomposite (NC). All the fabricated materials were detailly characterized via SEM, TEM, XRD, FT-IR, and DSC analyses. Beyond, outdoor experiments, under direct/indirect solar exposure, were conducted to determine the thermal performance of the nano-enhanced PCM specimens compared to pure PCM. For each experiment, direct/indirect solar absorption, four specimens were prepared: pure paraffin wax, nano-CuO-enhanced paraffin wax, nano-Co3O4-enhanced paraffin wax, and nano-CuO@Co3O4-enhanced paraffin wax. As result, all nano-based PCM cases had better performance than pure PCM. Among them, the nano-CuO@Co3O4-enhanced PCM recorded the highest temperature, at noon, with an enhancement ratio of 14.15% compared to that of pure paraffin wax.read more
