I live in DRY XXTREME SW Utah.

I have two 20' x 8' containers. Inbetween them is 16' of space. I am
enclosing the ends of the space with covered gates, and putting a
roof on the whole 1320 sf.

I want to put evaporative coolers in there. I see them that are
stationary, and pull outside air and blow it inside. I also see roll
around evaporative coolers.

Which one works better? It seems that pulling 105 degree air from the
outside and cooling it would only give so much of a temperature drop.
Pulling inside air, say 85 degree and cooling it might work better. BUT, the
inside air would be humidified somewhat, and I don't know if
the evaporative effect would be as great.

Plus, the roll arounds seem to have to be filled manually, although I
could use a hose, but that would be just another trip hazard on the
floor. Stationary ones would have a hard plumbed copper pipe, and
would stay full automatically.

I would actually like to have the roll arounds for inside the
containers so that I could move them to the container/s in use. And
for the space between, a stationary one would be good.

Just wondering how the roll arounds work vs. stationary ones.


Swamp coolers will only work if the water will evaporate. Used inside a closed
space, they will quickly stop working. I'd think the outside air units would
work better in the long run.



If it is sunny, those conex containers will become heat masses and
radiators. Shoulda put a higher roof over the whole thing, so air could
pass through and suck the hot air out. If you have not painted the
containers and roof white, you should consider it. Do a Google image
search for 'CHU', to get some ideas for what has worked over in the
sandbox. Lots of things that look like giant carports, and things to
provide shade from prevailing sun direction.
