Re: [EnergyPlus_Support] Uncertainty with Energy plus Enthalpy inputs for PCMs

["nedimho@xxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Dear Jeremiah,

I have a quick question about the MaterialProperty: PhaseChangeHysteresis object. I already looked in the input/output difference and can't figure out the difference, maybe it's a language barrier, however I hope you (or someone else) can clarify.

What is the difference between these two:

1.8.9.1.6 Field: High Temperature Difference of Melting Curve

This is the width of the enthalpy/specific heat melting curve, on the high side of the peak melting temperature, in Kelvin (technically it is â??change in Kelvinâ??).

1.8.9.1.8 Field: Low Temperature Difference of Melting Curve

This is the width of the enthalpy/specific heat melting curve, on the low side of the peak melting temperature, in Kelvin (technically it is â??change in Kelvinâ??).

 

 The material I am simulating starts melting at 23°C and finishes at 28°C. The peak melting temperature is 25°C.

I am very confused on what values to input under High/Low Temperature Difference of Melting Curve.

Thanks in advance!
