Introduction: How to Make a Cheap & Portable Air Conditioner / AC Unit



(Sorry about the widescreen issue, trying to fix it now)

I created this while playing badminton with my dad outside. It just came to me so here is how to make a cheap,easy AC unit.

Step 1: Step 1: Materials

The materials are below in the image. If the captions don't show up here: Tin foil, duct tape, paper plate, scissors, clear plastic wrap, salt (lowers melting point, basic chemistry), and finally ice.

Step 2: Step 2: Wrap Tin Foil Around the Paper Plate

Wrap the paper plate in tin foil then tape it together with duct tape.

Step 3: Step 3: Add Ice

Add ice. It is crucial that you add salt because it lowers the melting point for the water which will make it change from solid to liquid to gas quicker.

Step 4: Step 4: Cover in Clear Plastic Wrap Then Secure With Duct Tape

This is the final phase. It is now a cheap quick AC unit. I hope you enjoy!

So how does this cool off a room?

This would hardly help to cool someone down.
A wet frozen towel on the head would work better.
But good job anyways :P

Do you move air over this at all (like with a fan)? L

What do you mean?

Do you blow air over the ice to circulate cold around the room, or do you just let natural air currents cool the space? L

just let it stay, unless you would add a fan to the mix which would make the room cooler but dystroy the whole purpose of this tutorial.

Thanks, if I understand you correctly, there's no fan because this is cheap and easy? Have you measured how effective this is (e,g, with a thermometer)? L

I tryed but the only thermometer was a medical (ear?) one and didn't work out too well, my cousin then did a before and after test, 3.5 out of 5 for it's coolingness, 6 out of 5 for weirdness.

Well it's easy - you don't mess with expensive copper-pipe and stuff. L
