This particular home air cooler project is powered to run on solar energy, which makes it more complete when it comes to sustainability.
Homemade Solar Powered Air Cooler
This project makes maximum use of sustainable resources to lower the cost of materials and infrastructure necessary to start up a house with all its essential requirements. There are many ways to heat with solar energy, but cooling can be a bit more of a challenge. Here’s a way to make a cheap and simple solar powered air cooler using an ice foam box or cooler, PVC tubing, and a fan. The fan blows air through the ice, and the cooled air is expelled through the PVC pipe. The block of ice used in this example lasted for about 10 hours inside the cooler.
To build this unit, you just have to cut the holes in the lid of the fridge to insert the tube and the fan. Connect the fan to power (in this case, the fan is powered by a 15-watt solar panel), add the ice, turn on the fan, and enjoy the fresh air.
Depending on how fast the fan is running, this unit blows air that is between 38 and 45 degrees Fahrenheit (4 to 7 degrees Celsius). Since it is powered by solar panels, the fan speed is variable depending on the amount of sun hitting the panels. Actually, on hot sunny days, the fan should run at high speed.
Although this project is designed to work in a sustainable way , it can also work in the same way with electricity, simply by connecting to the power that is already installed in your house. In the following video you can see the step by step of the elaboration of this homemade cooler.
