<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have been trying to model a sunspace on a residential
building and incorporate forced ventilation from the sunspace into the
adjoining space. I have defined a forced-recirc wall parameter and assigned
this to the construction that I’ve assigned to the interior wall. The
interior surface is defined in the sunspace. There are three sunspaces but my
understanding is that you can only have forced convection across one therefore
I’ve only assigned my wall parameter to one of the internal walls.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The issues is that I’m not seeing any difference in
output with and without the wall parameter assigned to the wall. I have read
over the help documentation and it appears that I’m modeling this
correctly. When I view the hourly output there are plenty of instances where
the sunspace is hotter than the adjacent zone and is within the temperature
parameters I’ve assigned; however, no ventilation is occurring. Does
anyone have any experience with modeling sunspaces? Any ideas?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
