The basic principle behind PCM thermal energy storage lies in the material''s ability to absorb and release heat during phase transitions. When a PCM reaches its melting point, it absorbs a significant amount of heat from its environment. This process is called "latent heat storage". The PCM absorbs heat without increasing in temperature.
