Staying cool with out air conditioning

[deejaaa]

would using peitier plates eliminate the need for ice? use closed loop liquid. I can't seem to think of a way to remove heat with a cabin mounted system without being over complicated. extra cabin heat could make it unbearable but it already is sometimes.
has condensation been thought of? NM might not have a lot of humidity but this close to the Gulf we do.
look forward to seeing a working model.

It has some condensation, I don't think its bad enough to cause any problems.
In NM it has been one of the wettest years on record so far and very humid this year swap coolers are useless.

As far as the working model I am still working on the cooler. I rounded up all my supplies for my cold reservoir and I think I finely settled on a expandable modular design.

i will stay tuned because i see potential.

This is what I am doing with the cooler so far.
The pickup tube is 1/2''ID braded PVC.
The discharge is a 3/8''OD that is expandable with lines that branch off and go up and out of the cooler with with 8mmOD lines. The tee fitting with a plug shoved in it is there for future expansion, the 3/8''OD line will act kind of like a manifold. As I need more cold water outlets I can add them as needed.
The return in the middle of the lid is 3/8''OD.
All the pressurized line in side the cooler is stiff polyurethane.
Not sure what to do with the wiring, might use a gland seal.


I am using the good SMC brand connectors. They are not the cheapest but they are the best I know of. I ordered a bunch of them off ebay.
Just search "SMC tee" and select business industrial. Zoro has a lot of them.

cool! pun intended!

For the seat I was going to copy this:

No original thought what so ever.
And cover it with my dogs zip up bed cover.
Only differences will be I will use a ton more tube, 8mmOD feed, 3/8''OD return, a bunch of tee splitters, more paralleling and go completely over board with 1/4''OD tube and try to use up the 4mmID tubing I have. I want to put about 40 to 60 feet of line in just the lower part of the seat.
1/4''OD tube is cheap.

Just wondering if you'll get condensation on the outside of your tubes leading to wet seats?

Sure there will be some condensation but noting like wet seats like you get from when you leave a window down in the rain.

Could you add one of these to a beaded seat cover? I thought that was the Ecomodder method of preventing sweaty seats!

The Peltier junctions are terribly inefficient.You might have to piggy-back them ,where each is rejecting heat to the one downstream.
Or run an inverter to power a wall-mounted water cooling fountain compressor/heat exchanger/etc. to create chilled water enough to handle the 300-400 Btu's/hour basal metabolic heat load.
