PCMs simultaneously change the phase from solid to liquid (energy absorbing) and liquid to solid (energy releasing). Therefore, a PCM should be thermally stable even after few cycles of operation. However, some researchers [23], [96], [113], [211] reported that most of the PCMs are thermally not stable after few cycles of operation.
The most commonly used phase change materials (PCMs) are fatty acids, paraffin waxes, hydrated salts, and eutectics (Farid et al. 2004 ). Paraffins fulfill the maximum requirements for use as PCMs as they are consistent, chemically inert, nontoxic, predictable, and stable below 500 °C.
