The energy is adsorbed when the material changes in state, from solid to liquid, and it is released when the materials changes in state back from liquid to solid. The thermal energy transfer during phase changes occurs in nearly constant temperatures, otherwise than in other materials used as thermal insulation. PCMs combined with traditional insulation material - PUR foam, highly improves its thermal behaviour heat storage capacity.
In the Bricker project, our PIR foams with embedded PCMs will be applied in Belgium demo site. The building envelope will be insolated with this material to minimise the thermal losses.
