Ahmad,
I am aware of three components for modeling PCMs. Unfortunately none
of them are in the standard Trnsys library.
There is a free one in TRNLib
(https://sel.me.wisc.edu/trnsys/trnlib/library16.htm#thermalstorage). It
was written quite some time ago and donated by the author. It will need
to be recompiled as a 64-bit dll if it is to be used with v18 or you can
use the 32-bit version of Trnsys18. In order to recompile, it might need
some source code changes that would be detailed in the 07-Programmer's
Guide manual. I don't have any direct experience with this model but
know that it assumes the PCM to be on the outside surface of the wall
(in contact with the zone air)
Transsolar offers a stand-alone PCM component called Type399. You can
see some information (including downloading the documentation) here:
https://trnsys.de/en/addons-en. Again I don't have any direct experience
with the model so unfortunately can't offer any advice.
The third one is a model that I wrote some years ago and that we
offer as a stand-alone component. I can send you technical information.
The component listed here:
http://trnsys.com/tess-libraries/individual-components.php.html. This
PCM model assumes that the PCM layer is somewhere within the interior of
the wall (i.e. not in direct contact with zone air although there are
some ways to get around that.
I do not know of a cool roof paint model though as a side note, part
of the idea of Trnsys is to make it possible for users to develop and
add their new components.
kind regards,
David
