Phase change materials (PCMs) are substances that can absorb or release heat or cold during their phase change. They can store very large amounts of heat in a small temperature range around their phase change temperature. As a result, they outperform conventional sensitive storage materials (e.g. hot water storage tanks) by a significant margin.<\/p>\n

In contrast to sensitive heat storage materials, which only absorb or release heat in the form of a temperature change, PCM change their aggregate state when they absorb or release heat; they change their phase. In this process, the measurable temperature of the medium itself does not change or hardly changes at all. The stored energy is hidden in the phase change of the PCM, which is why PCMs are also referred to as latent heat stores (“latent” = hidden). Therefore, in addition to sensible heat, PCMs can store large amounts of latent heat in a small temperature range near their phase change temperature.<\/p>\n

One area of application for PCM materials is the passive, temperature-controlled transport of goods (TempChain). Here, with the help of PCM, the temperature inside the transport box can be kept constant for several days without an external energy supply.<\/p>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n
