Re: [EnergyPlus_Support] Wall with PCM



Dear Ghula,

PCM properties will only work if it undergoes phase change. This will happen if PCM sees the temperature range at which it changes the phase (in your case between 23 and 24 deg C) otherwise it will be a normal material. Try to fix the indoor temperature and may be an insulation to the exterior of your wall, see what happens . extract the node temperatures and see if it undergoes phase change. if PCM changes the phase, its temperature remains constant at mushy region for some time before it becomes liquid or solid.

Subject: [EnergyPlus_Support] Wall with PCM

 
Hello,

I am working on my university study project and trying to simulate a building envelope with Phase Change Materials but it is not considering its phase change properties. I am getting the same answers with/without using phase change property. I have tried to change the positions of PCM and the building envelope on different walls but could not get the answers. I have also changed the weather files but could not get the answers as someone has suggested to a similar problem asked by a person. I have also attached the idf file, if someone can look where the problem is existing. 

Thanks
