Staying cool with out air conditioning

Almost all the surface of the 13x22 backing I used is covered with 1/4''OD PVC line that will have water flowing through it (no spacer lines used).
Yes I will get a picture of it up here pretty soon.

I went from 30 feet of randomly coiled tube in the quick and dirty proof of concept test to between 80 to 90 feet of tightly packed fairly uniform tube as you see here.
On the left you have all the return lines, on the right is the feed line.

Remember, this is just one section out of as many as 2 to 4 sections.
If this doesn't do it I don't know what will.

On the subject of 11mmID line, it can be rather difficult to find. So I just used some 3/8''ID rubber fuel line.
3/8''ID PVC will not fit over the 11mm barb.
This little number has 11mmID ends with double 1/4''OD outlets, I bought 20 of them for cheap.

These are going to my return manifold.

Then today this finely came in:


I must say it actually works. At least the fan cooling part.
Its not exactly like sitting on ice water chilled PVC lines but it beats the heck out of nothing.
I mainly wanted it for the heating function for this winter.
All for only $50 shipped to your door (USA).

I figure if condensation were to be a problem with the ice water cooling rig I would simply put my ice cooled rig over top of this and use the fan portion and maybe some heat to dry the seat cooler when its not running ice water through it.

I tested the PVC loop pad.
First I tested the loop drains to make sure they all flowed a some what even amount of water and they did.
Then put ice on the water and sat on it.
After 20 minutes it was uncomfortable and after 30 minutes it was cold enough to start to be painful.

Hah, so what is the plan of action then? Use a PWM circuit to dial down the flow after a while?

The surflo pumps warn against giving them reduced voltage.
I was simply going to use a bass boat live well pump cycler.
These timers are built specifically to cycle small 12 pumps like this on and off to keep your catch or your bate alive and your boats battery from getting drained.
What this battery saving pump timer does is turn on the air or water circulating pump to a boats live well for 30 seconds, then it cycles off for a selectable time any where from a few seconds up to 5 minutes.
The contacts are rated for 10 amps, my surflo running under almost no pressure draws about 2 amps.
Since this little project is coming along so well I went ahead and ordered one last night. It was only $35 with shipping.

I also noticed my little cooler can become really full of spent ice, so full that I don't really see how I will be able to dump it with out unhooking everything from it.
I could just scoop out the water with a cup, if there wasn't several inches of ice on top.
Since I am going to run water injection it would make more sense to be able to pump that water into the water injection tank. So I think I will install a 3-way solenoid valve to the send the return water back out through a dump port.

here's an interesting article on instructibles that might have some info.

This isn't related to cooling your shirt or seat. But a swamp cooler could be an option in keeping the interior cool.

It adds moisture in the air which could be an issue in some cases.

Old VW's used to have them on the outside, but I guess you could find some space to mount them somewhere away from the air stream.
