Washing Up
I’ve got a little project I’m going to build just to see how well it works. It’s a portable air conditioner. It’s based on an idea I saw on the net. The ideas start simply and get more complicated.
The simplest version is to have copper tubing mounted to the back of a fan and use an aquarium pump to push ice water through the copper tubing. The tubing cools the air and the fan pushes the cold air forward.
A more complex version uses an insulated chest, a radiator (small automotive heater core), bilge pump, and ice water to blow cold air. It was able to cool a 95 degree car, in weather with a heat index of 108, down to 75 degrees in 5 minutes. The unit had an output of 65 degree air. The ice lasted for nearly an hour.
Using that design, but on a much larger scale, you can build a room unit with a box fan and a larger radiator and larger ice chest. If you use milk jugs and 2 liter bottles to freeze water, you have reusable ice packs that can easily be changed as needed.
Very interesting. I’m going to try this on a small room shut off from the rest of the house and see how well it works.
Here’s a rough drawing of the concept.
