To make an ice-chest air conditioner, cut two holes in the lid of a large Styrofoam cooler filled with ice packs so that one hole holds a downward-facing fan while the other holds a PVC pipe. When the fan is turned on, cool air blows out of the pipe.Continue Reading
A large foam cooler works best for making an ice-chest air conditioner. Using a razor blade or a sharp knife, cut a hole that is slightly smaller than the diameter of a standard fan. The second hole should create a tight fit around a PVC pipe, preventing it from falling into the cooler.
To create cold air, fill the cooler 1/2 or 3/4 of the way full with ice packs and replace the lid. The fan sits in the larger hole, with the front side facing down, and the PVC pipe pushes into the smaller hole. When the fan is plugged in, cool air moves over the ice and out through the pipe to cool the room.
As the ice in the cooler melts, the outgoing air gets warmer.Switch ice packs every few hours to ensure a constant stream of cold air. Reusable ice packs are the cleanest and least expensive option for an ice-chest air conditioner.Learn more about Heating & Cooling
