Hello everyone,
I am opening an old question here that has no answers.
I am trying to model a sub-zero-temperature PCM with phase hysteresis incorporated on the construction walls.
The PCM has melting/freezign peak temperature of -21/-22 °C. However, the following severe error occurred after running the model:
** Severe ** <root>[MaterialProperty:PhaseChangeHysteresis][PCM_SP-17][peak_freezing_temperature] - "-22" - Expected number greater than 0.000000
** Severe ** <root>[MaterialProperty:PhaseChangeHysteresis][PCM_SP-17][peak_melting_temperature] - "-21" - Expected number greater than 0.000000
I am using the 9.2 version of EnergyPlus, but the same error occurs when using a newer version, such as 24.1.0.
Also, reviewing the InputOutput Document (V9.2) it is defined that the Peak Melting/Freezing Temperature as the center (peak) of the melting/freezing curve, in Kelvin.. However, on the EPlauch interface, it is defined in °C.
On the other version, 24.1.0, it is mentioned in °C in both the InputOutput Document and EPlauch interface.
