I'm using different pcms and getting the same result
I'm using the energyplus 8.9 version. I'm trying to simulate the energy consume with hvac and the thermal confort with natural ventilation. I'm using data sheet for 4 different PCMS and getting the exact same value of consumed energy and room temperatures in all the rooms of the simulated house. In material hysteresis Their latent heat varies from a range of 190KJ/kg to 250kj/kg, so its a pretty big difference. They also have a range of peak temperatures (from 21 to 28). It was expected at least a little change.
I've already tryed to use graus kelvin and celsius, since in the inputoutput reference it is said to use Kelvin but in the program has a C. Already tryed to change the HeatBalanceAlgorithim.
Have you already looked at example files to see how PCM is modeled in EnergyPlus? The top two to check are:
Also, to really answer your question you should either add the text of the PCM-related EnergyPlus objects to your post, or add a link to your entire input file in your post so that others can better answer your question.
