Discover how to make your own air conditioner!

An air conditioner is the best solution to finding refuge from the scorching heat of the summer sun, but buying one is certainly not cheap. In addition, although there are energy-saving models, the electric bill could still reserve a nasty surprise!

Today, however, we propose a trick to enjoy the same fresh air produced by an air conditioner ... almost for free! In fact, the energy usage will be equal to that of an electric fan and the necessary material can be acquired at a minimal expense. Let's see how to get started!

Materials

One electric fan
2 coils of copper tubing 
Plastic zip ties 
Compression units for copper tubing 
Wrenches
Scissors and pliers 
One plastic tube
Bucket
10 lb (4.5 Kg) block of ice

Start by laying the fan down on a flat surface (the floor is fine) and place the copper tubing over the front of the fan; if it is necessary, join the two coils of copper tubing with a compression unit and open them up to cover the entire surface of the fan. Fasten the tubes tightly onto the fan grid with the aid of plastic zip ties. 

Insert one end of the copper tubing into the end of the plastic tube and join them together with a metal compression unit.

Place a large block of ice and the end of the plastic tube in the bucket, so as to let the cold air circulate and flow inside the copper tubing.

Now, just simply turn on the fan and feel the cool fresh air flow from the ventilator! The only thing you have to do is replace the block of ice once melted, but it usually lasts quite a long time. 

This system works thanks to the three separate parts --- the cold air is conveyed from the bucket towards the inside of the copper tubing that immediately becomes cold due to the tube's high thermal conductivity. The fan blades push the cold and refreshing air into the ambient.

Here you have learned how to build an air conditioner ... that consumes the same amount of energy as an electric fan!
