Phase change materials (PCM) are excellent materials for storing thermal energy. PCMs are latent heat storage materials (LHS) that absorb and release large amounts of heat during changing the phase changes from solid to liquid or liquid to solid . The performance of TES and heat transfer depends on the thermal conductivity of the substance.
In conclusion, Phase Change Materials are a crucial technology in the quest for efficient energy use and regulation in various applications. Their ability to store and release heat energy at specific temperatures makes them invaluable in both everyday and industrial applications.
The placement, thickness of the PCM layer, and fusion temperature all have an effect on energy savings and temperature changes . Due to the fluctuating temperature, phase change materials have found numerous applications. Materials that melt below 15°Celsius are utilised to cool and ventilate the room air.
