Organic phase change materials (PCMs) have gained huge importance for thermal energy storage systems, but their applicability is restricted due to low conductivity and hardness. The aim of this research work solve the problem by developing a novel organic binary eutectic PCM employing paraffin wax coconut oil in mixture (ratio 1:1) soften comfort applications. 3D expanded graphite (EG) was used as filler enhance thermophysical properties eutectic-EG composite formed melt-mixing technique. percolation limit EG 0.5 wt-% form network matrix. enhanced significantly from 0.2 W m −1 K 0.55 at 2 pristine PCM. Differential scanning calorimetry (DSC) carried out analyse enthalpies temperatures composites. 50 consecutive heating cooling cycles performed conventional system showed good reliability composite. numerical 2D simulation conducted reveal heat propagation behaviour developed with post-EG addition validate results obtained experimentally. cost analysis reveals that per mean power approximately 100% lower than composite's outstanding property indicates its potential soft pads/cartridges human also solar applications medium temperature ranges.

Enhancing solar flat plate collector efficiency with advanced phase change materials and expanded boron nitride

Phase Transitions, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 17

Published: Oct. 21, 2024

Thermal energy storage, particularly through Phase Change Materials (PCMs), is gaining significant attention for its ability to enhance storage capacity and thermal conductivity. PCMs help alleviate the strain on renewable sources stabilize load fluctuations. This study integrates a novel combination of LiNO3-NaSO4·10H2O-NaCl with boron nitride into Flat Plate Collectors (FPCs) boost system performance. Composite Material (CPCM) increases latent heat value by up 245.80 kJ, enhancing decomposition absorption rates while reducing losses. Boron improves conductivity 25%, from 1.378 W/m·K 5.543 W/m·K, increasing CPCM's charging rate. The specific rises 4.2 J/g·°C 5 at maximum temperature 90°C. As result, collector's efficiency 15%, achieving an overall 88%. Water serves as transfer fluid, simulations are conducted using Python in Anaconda Jupyter Notebook.
