Hello!
I am doing a PCM simulation in energy plus. To do so, I'm using the object MaterialProperty: PhaseChange. The object itself is very trivial and the input parameters are straightforward, however, the PCM I am trying to simulate has two different histograms. One Enthalpy-Temperature diagram for melting and another for the solidification. To go along, it has different thermal conductivity, density and specific heat values for both solid and liquid states. What is confusing me is that E+ requires only one set of temperature-enthalpy inputs. Which parameters am I supposed to enter, the solidification or melting? Is there a possibility to enter both? For my base-case simulations I have used the melting histogram. As for the thermal conductivity, I believe it is solved with the object MaterialProperty:VariableThermalConductivity, however density and specific heat remain with one input only.
What would be your suggestion to keep the simulation as accurate as possible?
Thank you in advance!
