Question

Why thermal conductivity of phase change materials is considered constant

Answer 1

Measuring the Thermal Conductivity of PCMs

Phase change materials (PCMs) are widely used in energy-efficiency initiatives for Thermal Energy Storage (TES). PCMs are interesting because they store the thermal energy of a phase change, called the “latent” heat of phase change, on heating, and then when cooled, they can give off the stored heat by reversing the phase change. This phenomenon may be used to moderate daytime temperature variations in a housing environment, to help mitigate the urban heat island effect, to ensure thermal comfort in bedding, cool electronics and for a variety of other applications.
