Although we live in Georgia,we have no central air conditioner or even a room air conditioner. Most of the time our single fan keeps us cool enough to be comfortable but over the last few weeks we have been having quite a heat wave. Temperatures have been in the mid nineties with high humidity so the heat index has been at 100 or more for several days now and is something we are not all that accustomed to. If we were employed perhaps we would just go out and buy an air conditioner but were aren't so we have to make do with what we have on hand in order to try and cool ourselves down a bit. In our internet travels over the last couple years we have run across the hillbilly or redneck air conditioners that folks have made so we decided to give it a whirl and see how they work.
This is not green or exactly eco friendly, but it is using what we had on hand, recycling it and making the appliances that we have already sucking juice work a bit more to earn their keep. This is also not anything like an air conditioner and will not cool your home down like an air conditioner, but it will bring the temps down to a more tolerable level.
Rather than make a whole new tutorial on this, I will refer you to the tutorial that we used for our project. We mostly followed this, but we used an old water cooler instead of a foam one and we used an inline diaphragm pump from the old trailer we scrapped instead of the one like they use in the tutorial. We made the copper tubing able to be untied from the fan so that we can move the fan and use it as needed. Lastly, we hooked the pump up to a battery rather than electricity because we could.
This cost us zero dollars to make and took about an hour of time when it was all said and done. The other day after setting it all up we managed to cool the room by five degrees in about a half hour. The one down side that we have seen to it is that the ice melts rather quickly and because of the style of pump we used we can only run it for short periods at a time. No matter, it has served its purpose and it has been fun to experiment with.
We made ours with a box fan complete with dust, but we have seen them on all types of grated fans.
