Entering the hottest summer months, the high temperatures have not been long in coming. If you don’t have a air-conditioning in your room to avoid sleeping drenched in sweat, or you don’t want your electricity bill to reach stratospheric levels, these simple home methods they could help you stay cool in your home.
With a box and a fan
Although our homemade invention cannot compete with professional appliances, it will help us to refresh a small room in the house. This contraption composed of an elbow of PVC Pipe, a little fan Y a box or cooler, it will refresh us for 30 minutes.
Using a utility knife, cut a hole in the lid of the box or cooler. We must make sure that the hole is the same size as the cage that covers the fan blades, if it has one. The fan you must push the air into the box so that the cord or plug is on the outside.
Next, make one or two more holes, on the side faces of the box and preferably on the side opposite the fan hole. It is vital that the holes are the size of the tubes so that they fit perfectly. Once this step is done we will have our little invention up and running. You just need to put inside a bag or ice sheet, which will act as a cooling agent.
Eco-Cooler Air Conditioner
Made of recycled materials, this eco-friendly alternative does not need electricity. It was developed in Bangladesh, where the heat and high temperatures reach 45 degrees in summer. The company Grameen Intel Social Business designed this simple method that allows to lower the temperature by 5 degrees in a few minutes.
With a simple board and a few plastic bottles As main materials, Eco-Cooler works simply with a pressure difference system. Plastic bottles are cut into two parts and laid out on a board. The board is placed in a window, with the bottlenecks facing into the house. In this way, we will refresh the house naturally.
What’s more, this company has shared the manufacturing instructions online, so that anyone can copy the system and make one at home.
With ice and a fan
One of the simplest alternatives is to place containers with ice in front of a fan. Just make a couple of plastic bottles, pierce them and insert the ice. Through the use of wire or a cord we hold the bottles in our fan, so that the expelled air will have a low temperature and will cool a room. It agrees place a towel or container underneath fan, which will absorb the condensation produced.
If you are a skilled person, you can ditch the simple amateur tricks and build a real air conditioner. Through thermoelectric plates, various tools, a wooden board and used computer parts (such as heat sinks, PC fans and a power supply), we can manufacture a network connected air conditioner, similar to those for sale in the market. In this video tutorial they explain how to make it, step by step.
