Here's an Instructable to make a simple, cheap, and energy efficient air conditioner with basic materials, and should cost less than $5. How it works is evaporating water in the
A/C (air-conditioner) pulls heat away, making the inside cold. The fan sucks air through the A/C, making the air cold. The warmer it gets, the more effective this A/C gets.
And it's easy on your wallet!
The materials are:
-popsicle sticks (about 20)
-cooling fan from computer
-solar panel, batteries, or other low voltage power source
-cloth that absorbs well
-scissors
-hot glue and a glue gun
-water

Signing UpStep 1Cooling fan... Meet the popsicle sticks.
You can get cooling fans free from computer repair shops and are in power supplies.
Once you find a suitable one (bigger ther better), stick six popsicle stick like the picture below.
You can trim the round ends with scissors if you want.

Batteries should look like [+||||||||||-][+||||||||||-][+||||||||||-]
It should say on the battery, but the positive end is the one with the nub, and the negative is the one without it. Make sure the ends are touching and using some packing or duct tape to keep them together. Then, use some wire to connect it to the fan. It should have two or three wires on it. Red or white are positive, and black is negative. If there is a third wire, like you said in the other post, it is ground. Those are typically green, or in your case, yellow.
Ignore that wire.
It should work when you attach the wires. If you would want it to be more powerful, you can most likely use four AA batteries to get 6 volts. It will be fine. Don't use any more than that, though.
The yellow wire is a ground or something. You don't need to wire it to anything but you can attach it to the black wire if you want. Good luck!
I know it has something to do with De-humidifier and air conditioning condensation. I'm not soliciting info from other users or selling this product, just wanting to stir up some interest in our community for different design builds and open-source instructions for such a thing. ;)

Using a thermometer and hygrometer, determine the temperature and relative humidity of the ambient air feeding into the cooler. Find a psychrometrics calculator or chart (like ASHRAE #1) online and use it to determine the wet-bulb temperature. You'll likely see a temperature drop of 50-75% of the wet bulb depression.
These don't work well in humid climates (coastal areas, especially). In the southern U.S. where cooling design conditions are in the range of 95 F (dry bulb) with a coincident wet bulb temperature of 77 F, the theoretical best you could achieve would be 77 F, but is usually in the range of 80 F, depending on the cooling efficiency of the system. I'd suspect that this system would be quite inefficient, owing to the ill-defined flow paths and heat gain from the fan motor.
i built one before
Give silicone a try. It generally dries to a workable hold in a couple hours, completely in 24 hrs (probably overstating drying times). Another nice thing about a tube of silicone is that, even if you leave half a tube sitting for months, only the tip is dried out. Give a squeeze to the caulk gun, and it comes flowing again.
hot glue works fine
