Type 1270

PCM component Phase Change Material (PCM) Wal

A phase change material wall that can be implemented with Type56/TRNBuild. Type1270 is designed to interact with Type56. The user is able to specify the physical properties of the PCM (density, specific heat, melting temperature, freezing temperature, and latent heat of fusion) or can enter a code to choose a particular commercially available "BioPCM" manufactured by Phase Change Energy Solutions. It should also be noted that Type1270 models a pure PCM. From a physical point of view, this means that the PCM is assumed to to go through its freeze/thaw process at constant temperature, to have a constant specific heat in the solid phase and to have a constant specific heat in the liquid phase.

This model assumes that the PCM layer is sandwhiched between other layers in the wall and that it is not in contact with zone air.
