Interesting Air Distribution problem.
Interesting Air Distribution problem.
(OP)
Please help me with this problem:
In our storage warehouse (70'Lx30'Wx30'H), we have problem with air distribution. We don't have any heat below 14' High. Our return air (Louver) located about 25' above ground and so our duct space diffuser. I am thinking that maybe Returned air is the same Elevation with Supply Air Diffuser so the Supply Air is forced right back to Return Louver.
I am planning to lower the Diffuser elevation about 5' and the Return Air Louver to ground level (3' above ground). Please let me know if any of you have dealt with situation like this before. Thank you!

of supply going directly into the
return all rolled into one problem.
Sounds like your on the right track,
lowering the return 3 feet above finished
floor you will solve
both aspects of your problem.
If your lowering the supply 5' from
present position, I have to ask...
Do you have anything stored above
the new proposed supply air level ?
Are the goods being stored required
to have temperature and humidity
control within tight limits ?

For high spaces, locating the return down low works fine.

covered in many text books. I would suggest
a number of smaller fans for better distribution.
A quick search on google should give you
plenty of options and lower energy bills too :)

I second (or third?) the notion of destratification fans throughout. These can be automatically controlled by thermostats placed strategically high and low and taking an average difference to energize and/or control destrat fan speed.
That would be a fix. Modifying air delivery and return locations would also be a fix. Vr, -CB
