how make an AC

Air conditioning uses up 20 percent of all of the electricity used in the U.S. If you want to skip the expense of air conditioning or help the environment, then you can build your own air conditioner with either a box fan and a cooler or with a box fan and a radiator. Follow this guide to build your own air conditioner.

Method One of Two:
Build Your Own Air Conditioner with a Box Fan and a Cooler
Edit

1
Unscrew the front gridded panel of your box fan.

2
Twist 1/4" (6mm) diameter copper tubing in concentric circles starting at the center of the exterior side of your grid.
Attach the end of a length of copper tubing to the center of the grid using zip ties.

Twist the tubing into a tiny circle. Continue twisting the tubing around the original circle until you have a series of concentric circles. Connect the tube to the grid with zip ties.

You want plenty of tubing attached to your fan grid, but not so much that air can't pass through the spaces between the tubing.

3
Screw the front, with the tubing attached to the exterior, back onto the box fan.

4
Attach one end of a 3/8" (9.5 mm) clear pliable tube to your fountain pump and the other end to the top end of your copper tubing. The ideal tubing for this project is the type of tubing used in fish tanks.

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

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

7
Wait an hour to allow your plumber's putty to dry.

8
Fill the cooler with ice water. Submerge the unconnected end of the second plastic tube beneath the water.

9
Place the fountain pump in the cooler.


10
Put a towel under your fan. The towel will catch the condensation that will form on the outside of the copper pipes.

11
Plug in the fountain pump and turn on the fan.
