in my case, we have two test cells which we created a partition in middle of it (one with incorporation PCM and another without PCM), now i try to simulate these two test cell for verifying experimental results, also we put a data logger to measure ambient temperature of cells in two direction (north and south surfaces).
i don't know, where is wrong in .idf file , maybe because of enthalpy-temperature (i put your example file data).
i try to check other parameters again.

Put insulation, or nothing in place of brick is what I would do, as most buildings are "light weight" and would not have such brick.
I would say you are getting close.
Could you please describe in detail the goals of your project?
Thanks

I tried, i got reasonable result between reference and PCM almost 3 -4 degree also i put brick again in partition and result was same as before i did(no difference), but the differences between experimental and simulation is too high (almost 10-15 degree), what can i do?Sent: Monday, March 5, 2012 7:13 PM

Try this and let me know..On Mon, Mar 5, 2012 at 11:02 AM, Mohammad Kheradmand <mohammadkheradmand@xxxxxxxxx> wrote:
I try to retrify experimental result, i cant move to outer wall, so it is necessary to be on outer layer of partition, my weather file refer to 2005 i don't know, how can i convert to 2011 as a new one? also the thickness is fix .thanks

Try moving your PCM to an outer wall, or changing your weather file, or changing the thickness of your PCM.Also make a spreadsheet that compares the two in terms of percent, as small savings in kWh for a single day may be bigger savings then it seems by just looking at kWh.Let me know if you still have the issue after experiments..On Mon, Mar 5, 2012 at 9:50 AM, Mohammad Kheradmand <mohammadkheradmand@xxxxxxxxx> wrote:Could you please help me , what is wrong ? why i have, same results between two simulation?regards--Jeremiah D.
