Profile of Market Area
Phase change materials are used for hot and cold storage. These materials can absorb heat within a certain temperature range without undergoing a significant change in temperature. Instead, the absorption or release of the heat is accompanied by a change in the aggregate state of the material.
Some materials are able to store huge amounts of heat while melting. This energy is released again during the crystallisation process. The temperature of the material stays almost constant during the melting and crystallisation processes. Therefore this kind of heat storage is called latent heat storage. By using materials with high melting enthalpies it is possible to store huge amounts of heat in comparable small temperature ranges.
Our researches at the Fraunhofer ISE focus on PCM based on different paraffins with melting temperatures between approximately 0 °C and 100 °C.
