<DIV><FONT face=Arial size=2>Good evening,</FONT></DIV>
<DIV><FONT face=Arial size=2>I am Sylvain CHATZ from ENERCOBAT engineering
office, working in France on high performant buildings design.</FONT></DIV>
<DIV><FONT face=Arial size=2>It's my first time on this list and my concern is
about PCM layers simulation on TRNSYS 16.1.</FONT></DIV>
<DIV><FONT face=Arial size=2>I've tried to use "type 204" proposed on
SEL web site, but documentation and example supplied are not
enough for my understanding.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><U>My questions are about the SUNSPACE example
supplied into the files package loaded : </U></FONT></DIV>
<DIV><FONT face=Arial size=2>There are 2 air zones in the TRNBUILD type 56 model
of this example : SunZone and BackZone.</FONT></DIV>
<DIV><FONT face=Arial size=2>SunZone is where "PCM wall" has been installed.
</FONT><FONT face=Arial size=2>So : </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- How to make the difference if we want "PCM
layer" into all walls surfaces from SunZone, or only into some of
them?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Why the resistance of the "PCM massless
layer" created in TRNBUILD is only 0.1 mē.K.h/kJ? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Why the "PCM wall" using the "PCM massless
layer" into SunZone (boundary wall calling T_PCM
input) presents a so small surface of 0.2 mē?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Why QCOMI is taken from the same "PCM
Wall" (14) and not from other walls?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Do we have to change values into the 4 text
external files supplied (NodeTemp.txt, Tila.txt, Ceff1.txt, ALKU.txt) or do
we only have to call their path? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- W</FONT><FONT face=Arial size=2>hy the PCMeT
(average surface temperature of "PCM wall") calculated by type 204 is sent to
the boundary "PCM wall" input (T_PCM) into type 56 ? </FONT></DIV>
<DIV><FONT face=Arial size=2>
type 204 receives QCOMI
from 0.2 mē surface (14), and T_AIR from SunZone volume, </FONT></DIV>
<DIV><FONT face=Arial size=2>
then it calculates
and sends T_PCM to boundary input for 0.2 mē surface
(14)</FONT></DIV>
<DIV><FONT face=Arial size=2>
=> I don't see in
which way this sequence allows modelization of PCM introduction
into a wall?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I certainly missed some key points to understand
the principle of this model. </FONT><FONT face=Arial size=2>Many thanks by
advance if somebody could explain how it works.</FONT></DIV>
<DIV><FONT face=Arial size=2>Regards</FONT></DIV>
