Welcome, today I will show you how to build a small air conditioner , the materials are easy to find and
the difficulty is very low, of course, does not have the same power as a true conditioner but given the low spending his
performance is is very good.
the materials to be used are:
-bowl polystyrene (alternative you can use plastic, I chose polystyrene for good thermal characteristics)
-old usb cable
-connection for 9v battery
-two cooling fans, usually are used for the cooling of the CPU or other electronic components
if you prefer you can see the video for view the final result!
Step 1: Cut the Polystyrene
the first thing you will need a polystyrene bowl
Take two fans( I used those to cool the cpu ) remember you will have to place them in a manner that draws air, while the other push off...
cut the polystyrene and place the fan.
Step 2: Prepare the Power Supply
Ok, now you can choose what power supply you prefer
for usb you have need a old usb cable... cut in half, inside you can found 4 wire: Red, Black , green, white. you have to save only red and black wire.
for power with 9-volt battery you need a compatible connector.
You can find this connector in a old 9-volt battery and soldering two wires to the two poles
after you have connect the wire together
the + and the -
usually the red wire represent the + pole and the black the - pole
Step 3: Solder the Wire
you're almost done! :D
now you have to connect the power supply to the fan with a solder, you can see the drawing of the circuit, but is a really simple job.
after remember to insulate the wire!
Step 4: Put the Ice in the Bowl and You're Done
put some ice in the bowl of polyestyrene, conect the power supply and check the temperature!
- do not mix the two power supplies
- when the ice melt, put the water out of the bowl
Congratulations you have finished the job!
