<br>I am an MSc student in Cardiff University and I am now starting my
dissertation on the use of water in the envelope of a building, in order to
regulate heat flows. I am new to TRNSYS and I would like to know if the
following is possible and to get some direction/guidance regarding these
areas:<br><br><font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2">1) Can water as a
construction material on the enveope of a building be modelled in TRNSYS?<br>2)
Can water flows (due to natural, or forced circulation, or from solar heating)
inside pipes embedded on the fabric of a building be modelled?<br>3) In the case
i can simulate a natural flow or circulation of water in a chamber, then at
which moments? under which circumstances? I reckon that even with a stable
incident solar radiation, the temperature of the water will be different after
10 minutes, 30 minutes 1 hour, or 12 hours. Can i calculate or simulate this
interaction of the incident solar radiation on the water chamber and its effect
on the natural flow of the it?<br>4) Considering a pipework or a network of
chambers that contain water and supposing that some of them are exposed to solar
radiation whereas others are in shade, provided that there is a natural flow of
water caused by the differentiation in temperature, could i simulate somehow the
heat distribution in the fluid? could the constant differentiation in
temperature and flow of the water in this network be somehow calculated?<br>5)
In the above case could i have different time "snapshots" of the system? To get
an idea how this mechanism behaves?<br>6) In the case that these water
chambers-containers form an enclosure, would i be able to simulate the
conditions in this enclosure caused by the presence and flow of water around
it?</font><font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2"><font color="#888888"><br></font></font><br><br>
