DIY: A Homemade Air Conditioner

A Homemade Air Conditioner

It is a time of much hot days and if you can't afford an air condiioner for yourself then don't bother about it. Now you can build an AC unit on the cheap and with readily available materials.

According to the US Department of Energy a typical window air conditioner will use about 10 times as much electricity as a fan — sometimes more, sometimes less, depending on the size of your AC and fan. Generally speaking, a fan is much more energy efficient. 

All you need is a fan, some tubing for the water to run through, a water pump, some twist ties (or zip ties), a cooler, water and some ice. The assembly is simple — the first step is to remove the front grate on the fan and affix the tubing with the twist ties. Then you attach the tubing to the water pump, fill the cooler up with water and ice, stick the pump in and press go. Voila! Some cold respite from the heat without the electricity bill — and green guilt — that you’d have with an AC unit.

Although we’re not sure that this homemade AC will cool you down as much as an AC unit would, it’s definitely better than a simple breeze. It works on the idea that if you pump cold water through tubing in front of the fan it will immediately cool the air blowing on your sweaty face.
