How to Create Your Own Adsorption Air Conditioning

Unpack and inspect the garden pond water pump. Look at the male connection inserts where the flexible tubing attaches. Determine if these are made for a 1/4-inch or 1/2-inch tubing diameter, which varies by pump size and make. Review the pump instructional manual, if you cannot determine which size tubing you need.

Fit a hose clamp over one end of the flexible tube. Attach the end over the pump connection insert. Tighten the clamp to keep the pump from leaking at this tube joining. Follow the same process to attach the other end of the flexible tube to the pump.

Place the Styrofoam food cooler 4 to 5 inches behind the fan. Sit the pump in the cooler.

Lay the excess flexible tubing in front of the box. Begin bending the tube and attaching it to the fan grill, in a curved zigzag shape, with the zip ties. Attach as much of the tubing to the fan grill as you can.

Pour water over the pond pump in the Styrofoam cooler, and add two large bags of ice to make the water cold. Make sure the water covers the submersible pump, as illustrated in the instructional manual.

Connect the pump’s power cord to the power outlet, to get the water to flow through the flexible tube. Connect the fan cord to the power outlet, so it starts blowing cooler air into the room.
