[bldg-sim] Simulation of Production Halls

[Peter Simmonds]

Here's what we do for such spaces. First calculate the space
stratification using the Effective Sensible Heat Gain (ESHG) method.
This will provide data on temperatures in the occupied zone and
temperatures of air being exhausted from the space. Use the space
exhaust temperature as the temperature set point in DOE-2 or transys.
This should provide a fairly accurate model, you can then study the
performance. I also think that IES can calculate stratification in
spaces.

You can always talk to Stefan Holst at Transsolar in Munich, he can also
help.

Subject: [bldg-sim] Simulation of Production Halls

 

Greetings Group,

 

I am a graduate student studying building service technology at the 

University of Applied Sciences in Munich, Germany. I am attempting to 

compare various indirect evaporative cooling systems in a large
production 

hall with displacement ventilation. Because the secondary air flow is
(in 

some configurations) extracted near the ceiling, I expect the effects of


stratification to be significant. Does anyone have experience defining
such 

a space or know of existing literature which might be of help?

 

The possible solutions I see are: coupling air flow with multiple zones 

(stacked), defination of plenum space or multiple nodes in a single
zone. 

Each possibility seems feasible, but I lack the experience to know which


assumptions are necessary to obtain realistic results. The simulation
should 

be on (at least) an hourly basis.

 

I am aware that this topic is not particularly new and have seen
multiple 

similar inquiries, but have not yet found a satisfying solution.

 

I have access to both TRNSYS and EPlus. The results of the simulations
are 

to be included in my Masters Thesis, in which I will compare 

investment/operating costs of various industrial hvac solutions for 

production facilities.

 

Any English or German language responses would be greatly appreciated!

 

Thanks,

 

John Olson
