The scorching South African heat can really take a toll on your body, we know it’s not summer just yet but this article we’re sure we’ll serve it’s purpose for years to come and the South African market. The concept is simple and can be easily with many who work outside or in hot working conditions, coming home to an even hotter house can be discouraging.
With the cost of cooling systems, many can’t afford to stay cool in their homes. However, this 10-step guide to making your own evaporative cooler could be the answer to your prayers.
Evaporative Coolers are incredibly energy efficient. In some cases, they have been shown to decrease a comparative air-con-cooling bill by up to 70%, meaning that you could save up to 60% of your monthly cooling costs over the course of a summer season. This really adds up, especially if you live in a hot, dry climate most of the year-round. Alongside these savings, evaporative cooler clears your conscience because they use so much less energy. This gives you the confidence to stay cool in the heat and know that you are being environmentally responsible in cooling your home or office. Your reduced energy usage turns into a lower carbon footprint, allowing you to give back to the environment.
For this project, you will need a 20-liter bucket with a lid; water; a drill (with circular head), box cutter or other sharp tool; a cooling pad; some window screen or garden cloth; a small, circular fan; a small fountain pump; about 1.4 meters of aquarium tubing; a clamp; a straight pin; and a power source.
Fill the 20-liter bucket with about 2 liters of water.
Use your box cutter or drill to cut holes into the bucket above the water line. Drill holes all around the bucket. The holes should be about 3.81 cm to 5.08 cm in diameter.
Next, you will need to cut your cooling pad to be about 33.02 cm to 35.56 cm high 76.2 cm to 78.74 cm wide. After cutting your cooling pad to this size, fit it inside of your 20-liters bucket with the water still inside.
Cut two layers of the screen or garden cloth to be slightly larger than your cooling pad and fit them between the bucket and the cooling pad. This will help hold the water and the cooling pad away from direct contact with the cooling apparatus.
Next, you will need to use your cutting tool to cut a hole in the lid of the 20-liter bucket. The hole should be the same size as your small, circular fan.
Fit your small, circular fan into the lid so that the front of the fan is facing outward and the back of the fan will be inside of the cooling system when running.
Place the pump inside of the bucket and attach it to a 1.4-meter aquarium tubing that is about a quarter inch to 3/8 inches wide. Then you will need to wrap the tubing around the top of the bucket one time and clamp the hose off. The clamp is important so that the water doesn’t escape quickly back into the chamber of the apparatus.
Poke holes into the tubing by using a safety pin or straight pin. This will turn your hose into a “soaker hose.” As the water is filtered up into the hose, it will leak onto the cooling pad, saturating it with water.
Hook your pump and your fan up to a power source. You can use any power source you’d like, including solar power, to keep yourself cool.
Enjoy your cooling evaporative system. If needed, check on your cooling pad. If it seems dry at the top, poke more holes into the aquarium tubing.
We hope this helps you stay cool in summer! Check out below for some great videos we found online which may be a little easier to follow! You could always print out these instructions and follow as you watch a video.
