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.
