How to Build Your Own AirConditioner

How to Build Your Own Air Conditioner


Air conditioning uses up 20 percent of all of the electricityused in the india. If you want to skip the expense of airconditioning or help the environment, then you can build yourown air conditioner with either a box fan and a cooler or witha box fan and a radiator. Follow this guide to build your ownair conditioner.

This is NOT meant to cool down a whole room, it just createsa nice cool breeze.

A Fan (box fan is ideal) A cooler (you could use a Styrofoam cooler or whatever cooler you may have on hand) An aquarium pump (or a pond pump, the higher the Gallons Per Hour the more cooling

you’ll get mine is a 132 GPH, also be sure your pump has enough power to push thewater to the height required to reach the top of your coil)

Copper coil tubing (the particular type of tubing I used was 3/8″ outer diameter coppercoil – 20 feet)

Vinyl tubing (my pump called for 1/2″ Inner Diameter tubing about 10 feetworth. Hopefully you get better tubing then I did I believe mine is the autokink brand)

Reducers and fittings to connect your copper coil to your vinyl tubing and ultimately toyour pump. If you are unsure a conversation with a hardware store plumbing expertshould get you going in the right direction. They were terribly excited about my projectso they were glad to help. (I used 2 1/2″ to 3/8″ couplers that were then fitted with5/8″ threaded couplers and then screwed in two 1/2″ barbed brass adapters to connectthe tubing, finally I used 3 1″ hose clamps to firm it all up)

Wood for making box fan outriggers Zip ties for attaching the tubing to your fan

Method 1 : Build Your Own Air Conditioner with a Box Fan and aCooler


Unscrew the front gridded panel ofyour box fan.

Procedures for building an air conditioner:

Twist 1/4" (6mm) diameter coppertubingin concentric circles starting at thecenterof the exterior side of your grid.Attach the end of a length of coppertubingto the center of the grid using zipties.

Twist the tubing into a tiny circle.Continue twisting the tubingaround the original circle untilyou have a series of concentriccircles. Connect the tube to thegrid with zip ties.

Screw the front, with the tubing attached to the exterior, back onto the box fan.

6Connect the other piece of 3/8" (9.5mm) plastic tubing to the bottom end ofthe copper tubing. Seal the connectionwith plumber's putty.

7Wait an hour to allow your plumber'sputty to dry.

8Fill the cooler with ice water. Submergethe unconnected end of the secondplastic tube beneath the water.

4Attach one end of a 3/8" (9.5 mm) clear pliabletube to your fountain pump and the other end tothe top end of your copper tubing. The ideal tubingfor this project is the type of tubing used in fishtanks.

5Roll plumber's putty in your hands to form a strip. Wrapthe putty around the connection between the hose andtubing and press the putty to seal the connection.
