I gave that some thought, you *might* do better with a dehumidifier
instead of a chiller, if you cant stick a fan in a window you
probibly wont like the effects of a chiller on the house temp, that
heat still needs to go somewhere. the dehumidifier itself wont cool
down the tank, it will just take the tropical house effect away from
using fans instead of a chiller to cool your tank.

The chiller will go in the crawlspace under the condo. In the
crawlspace, I can run a 12" flexi duct from a shaded outside vent to
the chiller's intake side. The chiller will then vent it's heated
exhaust to the crawlspace air volume.

is your floor well insulated? once you heat up the crawlspace, the heat has
to go someplace.

The crawlspace has about ten or fifteen vents around the perimeter of
the building, one of which will be covered by the intake. The others
should suffice to keep the crawlspace cool.

I thought about running the exhaust to one of the vents, but blowing
hot air out of a vent is much more conspicuous than pulling cool air
in through a vent and I'd really prefer that there was no way to tell
that the chiller was there at all...

I dont have to worry about CCR's :D but I do know people that do,
didnt know how they would go with a 12" duct,

The aquarium is on the far side of the building from the crawlspace
entry point (even repairmen going into the crawlspace wouldn't come
across it unless they were fixing something in my condo). The vents
in the sides of the crawlspace are 10"x6" holes in the stucco covered
by grille's. There's no way to see the duct for the 10' it needs
to run from the shaded vent I've selected to the spot under the
aquarium where the chiller will reside.

also I think id do
that backwards if possible or it will heat your house

It will heat the crawlspace, but the crawlspace has a lot of vents
around the perimeter of the building. My current plan is to see if
there's adequate passive flow to keep the crawlspace temps reasonable.

suck the exaust air out of the crawl space otherwise it will get way
past hot.

If the passive ventilation of the crawlspace is insufficient, I will
then try reversing the duct hookup, but because one of the vents will
now be blowing hot air out from the building, it will become
conspicuous to any pedestrian in that area.

Which is something I'd like to avoid. If nobody knows, then nobody
complains. If nobody complains, then my aquarium stays cool and I
don't have to heat or humidify my condo to do it.

Ross

my condo CCR's prohibit
A/C window units and there is simply no way to retrofit central air
into a 1948 building.


Something like that would make me absolutely furious. There is "No" way to
retrofit a/c AND you are not "allowed" a window unit?
Is this something unique only to California (it would not surprise me) or is
this a typical condo thing?



So no air conditioning at all is possible
within the condo.


What type of heat do you have?



I'm bending the rules on allowed electrical
equipment in the crawlspace, but if you don't tell, I won't...

Regards,
Ross



Okay, finally I have something somewhat helpful to say... What type of
clothes drier, if any, do you have?
Maybe you could figure out a way to "TEE" in to the vent and exhaust through
the drier vent. That way, no one would suspect anything if there was hot
air coming out. Naturally, this solution will present a few problems but
they can be overcome.


-OR-

What do you normally do to stay cool in the summer time? You might want to
consider some window fans. If you arrange a couple to blow air in and a
couple to blow air out on the other side, you can successfully increase the
air exchange rate thereby reducing your high humidity.
A couple of small fans on the tank in addition to this should solve your
problems.

i have recently purchased a few of these and i am setting them up by
putting
the intake from the other freezers out take. i have tested it on a
smaller
tank and it seems to due the trick... they are very cheep to setup....

http://www.oatleyelectronics.com/peltier.html#PELT2

i am just one up for my new larger tank....

Thanks Geoff



How long have you been running those? Are you certain that the water you
are cooling does not come in contact with any copper?

no copper all plasticits a sealed unit covered in platic. i have only been
running it for three weeks on a test tank... i will update as i have
completed my testing....

We're not allowed to install washer/dryer in the unit. But we have a
Maytag stacker if you must know :) The vent blows into the crawlspace
because we're not allowed to have it...

Yeah, things are pretty draconian. But it's four blocks from the
most amazing job I've ever had and I can afford it, so...

Occasionally open a window. That's about it. Luckily, that's about
all that's needed 99% of the time.

This is true, but I'd like to be able to leave for a week during the
summer and not have the aquarium fry while I'm away if the temp rises
just as I walk out the door.

I'm going to try several options. I'm pretty sure a chiller is going
to be going in, with all of the ensuing cost and trouble.

Thank you for putting some thought into it, though...

Ross
