I have a question regarding the capabilities
of IES VE and its CFD package and I was hoping someone might have some experience or insight to help get me started on the following problem. We have a concept cooling design which
includes a radiant hollow core concrete ceiling through which evaporatively cooled air is routed. The air which is routed through
the radiant ceiling comes from a central evaporative cooler and is then
exhausted at the exterior of each room after it has passed through the
airflow passages in the ceiling. Just to be clear,
this is not a typical radiant system in that electricity is being
used to cool the slab but instead evaporatively cooled outdoor air is
being used in its place. We also want to couple these effects with
natural ventilation which occurs because of the use of operable
windows. <br>
<br>We are trying to analyze the effects of these techniques in a cooling season in Colorado (hence the benefit of the evaporative cooler). We have conducted rough calculations using standard
ASHRAE energy transfer techniques and we want to verify our results.
Have you ever heard of this type of system being modeled in IES VE
and/or is it capable of modeling such a system? Is there a way to
modify the "radiant ceiling" option in IES to take into account the saving
which would occur by using evaporatively cooled air in the place of
electricity? If not, is there a way to manually create such a system
from the ground up using Modelit or sketch up? <br>
<br>Any help would be greatly appreciated. Thank you.<br><br>Rebecca Butler<br>LEED AP<br>Enermodal Engineering<br>(303) 861-2070<br><br>
