That was an ok attempt. But the heat from the fan would probably negate any positive cooling effects from the tubing. 
Here is another idea:
-Get disposable styrafoam cooler.
-Get a block of dry ice from the grocery store. ($2 or $3 per block around here.)
-Get some aluminum cans and empty them. (Hmmmm what kind of aluminum cans should be used?....and how should they be emptied?...lol.
)
-Put the dry ice block in the bottom of the cooler.
-Layer the empty cans across the top to form a solid layer of cans with the open tops facing up.
-Then have the fan blow across the top of the cans.
In theory, the aluminum cans will work as a heatsink in reverse. It will transfer the coldness from the dry ice to the air and the air from the fan will transfer the coolness to the room. As the dry ice evaporates no water will be left behind.
So how's that for Redneck Engineering.

cigarxtc - that sounds genius, and affordable. Paul is coming today to fix the A/C for good, but I'm still gonna try a few of these ideas. Thanks for all the input I'll let ya know how they work out.

You could flatten them, but in theory, if crushed you loose the insulating qualities of the air chamber inside the aluminum cans, thus cooling transfer could be increased, but at the sacrifice of a shorter lifespan for the dry ice block. But that is all just theory and I'm no rocket scientist, but I play one in my garage.

Looks like the beginnings of a swamp cooler. They work. You just need more heat sinks, to allow more heat to be absorbed into the cold water.

These work great, we use them on boats for overnighting.
It's a lot like what you're on track to build.

Ice to cool down beer.
Drink Beer.
Get drunk.
Put empty cans back in ice to get cold.
Still hot.
Remove cans and place on kitchen floor.
Lay down on top of cold cans.
Still hot.
Don't care. You're drunk!

Fill your interior with ice cold cans of beer. When they warm up, drink em and buy new ones. If the cops ask, tell them you're on your way to the recycling plant. Crush the beer cans on your head for good measure. (don't wanna stomp them with your feet, could hurt yourself, sprain an ankle maybe. And don't buy heneiken in cans. Rednecks can't afford it anyways, so you dont gotta worry about that.

Basically, you guys are all trying to build a swamp cooler. (kind of). everyone is trying to cool a coil of water with a fan blowing thru it. build something that will evaporate water as the wind blows thru it, now you are cooling the air. but these only work if the humidity is around 20% or less. in the summer my swamper will keep my house about 78 degrees when its 110 outside. a little water, a little electricity to run the water pump and the fan motor, and I'm comfy. Not free, but a heck of a lot less than my air conditioner. We turn that on when it gets humid.

Figure the parts of the house or trailer the sun heats up the most, and find a way to shade them. (step 1)
Gather cool air at night or in the early morning hours, and avoid leaving doors open longer than you gotta during the day. (step 2)
Look for stuff that creates heat in the house, and decide if it needs to run all the time (step 3)
Partition off "COOL AREAS" using blankets or hangings in the parts of the house you need to, or alternately create a "BREEZEWAY" where air can flow through the middle of the house and cool stuff off as much as possible.
Ventilate the attic so that it doesn't become an oven right over your heads. The average attic space can run up at least as high in temperature as a closed automobile in direct sun. That heat will radiate downward if not gotten rid of...
Just some thoughts, but you may find them both practical and effective!
