<P>Prof. Hakon Skistad et al have a great book on displacement ventilation that he had developed as a guide for REHVA. </P>
<P>The book is the first one on the link below -</P>

<P>I found this book a great source for identifying simulation methodology as well as general numerical theory on these effects for my own master's thesis.</P>
<P>Hope this helps...Good Luck!</P>

I am attempting <BR>>to compare various indirect evaporative cooling systems in a large <BR>>production hall with displacement ventilation. Because the secondary <BR>>air flow is (in some configurations) extracted near the ceiling, I <BR>>expect the effects of stratification to be significant. Does anyone <BR>>have experience defining such a space or know of existing literature <BR>>which might be of help?<BR>><BR>>The possible solutions I see
are: coupling air flow with multiple <BR>>zones (stacked), defination of plenum space or multiple nodes in a <BR>>single zone. Each possibility seems feasible, but I lack the <BR>>experience to know which assumptions are necessary to obtain <BR>>realistic results. The simulation should be on (at least) an hourly <BR>>basis.<BR>><BR>>I am aware that this topic is not particularly new and have seen <BR>>multiple similar inquiries, but have not yet found a satisfying <BR>>solution.<BR>><BR>>I have access to both TRNSYS and EPlus. The results of the <BR>>simulations are to be included in my Masters Thesis, in which I will <BR>>compare investment/operating costs of various industrial hvac <BR>>solutions for production facilities.<BR>><BR>>Any English or German language responses would be greatly
<BR>>appreciated!<BR>><BR>>Thanks,<BR>><BR>>John Olson<BR>><BR>><BR>><BR>>======================================================<BR>>You received this e-mail because you are subscribed to the <BR>>BLDG-SIM@GARD.COM mailing list.
