For the science fair at my school, I made the decision to try to make a makeshift cooling system.
- I got a few different ideas online and then I knew what I would try to put together.
I actually got a cooler that I would pack full of ice. I got some copper tubing that I carefully bent into a spiral shape and attached it to a fan. My whole reason for doing this was going to be to have a coil system with cool water flowing through it. When the fan blew the air, the air would be cooled down because of the ice-cold water flowing through the tubing. I hooked the tubing up to a water pump and then I put the ice and the water in the cooler. I had the tubing connected so that the water would keep on recirculating back into the cooler. When I had my makeshift A/C system working, I thought it was pretty good. It actually was able to cool me down substantially. It certainly worked a lot better than just the fan running on its own. When I had the makeshift cooling system at the science fair, I actually ended up winning 2nd place. The first place project was pretty cool too. There was a guy that made a solar powered heating system. It worked pretty good too, better than my makeshift cooling system. Not to mention, he was able to utilize the energy from the sun to make his work while I had to keep adding ice water to mine.
