About Phase Change Material
Phase Change Materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting & freezing (changing from one phase to another). When such a material freezes, it releases large amounts of energy in the form of latent heat of fusion, or energy of crystallisation. Conversely, when the material is melted, an equal amount of energy is absorbed from the immediate environment as it changes from solid to liquid.
This property of PCMs can be used in a number of ways, such as thermal energy storage whereby heat or coolness can be stored from one process or period in time, and used at a later date or different location, for example in solar energy building. PCMs are also very useful in providing thermal barriers or insulation, for example in temperature controlled transport. PCM can also be incorporated in thermal regulation textiles to control temperature change.
PCM Solar Energy Application Introduction
Phase change materials encapsulated with a sphere or other metal materials then used in the field of solar energy storage.The encapsulation PCMs used with solar energy,ground source heat pump,air source heat pump system, attain the purpose of efficient heat storage.
