Phase change materials (PCM) are materials with a high latent heat, which are able to store and release large amounts of energy (up to 100 times more than using the specific heat) to the phase change temperature (solid-liquid). A key feature of these materials is that, during phase change, the temperature remains constant while the material is absorbing or releasing heat. The phase change temperature is characteristic of each PCM. Their use is focused on improving the energy efficiency of the system where it is incorporated.
Mainly there are two types of applications: heat storage and passive temperature control
