ECO-COOLER : Build your own Aircooler with recycled plastic !

AMAZING : Build your own Air Cooler and reduce the plastic waste ! Easy to do, this air cooler is really fucking ecologic !!

ECOLOGIC AND CHEAP

A free air-cooler without electricity need

If you want to save energy and money, the best is to do it simple ! In Bengaldesh they really understood that and decided to build a new kind of air-cooler 100% ecologic…

#It doesn’t need any electricity !!

To be really innnovative they use recycled plastic, why ?

  • Everybody can do it
  • You can do it everywhere
  • You can do it from the street
  • You can help the planet
  • Really cheap

Try it !

How to do a Eco air cooler ?
  • What is Eco Cooler

The Eco cooler was developed by Ashis Paul from Bangladesh. The southeast Asian nation’s scorching heat was the main inspiration behind his DIY cooling system. Another thing that inspired him was the fact that electric air-cooling units wouldn’t be applicable in most Bangladeshi homes. In the mostly rural and poor country, electricity is sparsely distributed and mostly unreliable.

Ashis Paul created his air cooling system using a common waste item in Bangladesh: empty plastic bottles. The Eco cooler is the first-ever, zero-electricity air conditioner in the world. The inventor also wanted to help as many people as he could use his solution. That is where the Grey Group came in. Using its privileged position as an international advertising company, they posted the cooler’s plans online for free. Anyone with access to the internet can, therefore, design his/her own Eco cooler. Grameen Intel Social Business volunteers also helped in the building and installation of Eco cooler units. They also took part in teaching locals how to build their own and pass the knowledge on to other beneficiaries.

Difference between the Eco cooler and Air coolers ?

Why is the Eco cooler called a simple air cooler? The popularity of the Eco cooler and air coolers lies in their being environmental-friendly and economical. Below we spend some time explaining theirs features and cooling methods:

  • What is a air cooler

Air coolers are among the earliest forms of weather and climate control still in use today. Remember that breezing feeling you have on your skin after coming out of a pool? That is the simple idea of air coolers.

  • How Air Coolers work

The scientific principle behind air coolers, known as evaporating coling is quite simple. It refers to a fairly common natural phenomenon that regularly occurs in our environment. Perhaps the best way to relate to this is via the use of a swimming pool. That cooling effect that one experiences after coming out of the pool occurs similarly. As dry air blows through the water on your skin, it absorbs some of the water. As this water turns into gas, heat switches from the much higher air temperature to the lower water temperatures. This natural air circulation thus cools the skin area around it.

A modern evaporative cooler operates using the same principle. Its fan draws outside air to pass through wet filter pads. This filters any impurities in the air and decreases its temperature as the water in the pads evaporates. The resultant cooler air is then directed into the target building to circulate and cool it. The air cooler’s filter pads are made wet by a water pump. It pumps the water up to the top of the filter pads from where it then trickles down. The humidity concentration of the supplied air is raised. However, this isn’t necessary if the air experiences sufficient cooling

  • Eco cooler how it works

As hot air rushes into each plastic bottle, it is pushed to the rim where it begins expanding. This expansion then leads to the cooling of the air as it enters the target room. This cooling results from pressure change. As air enters the plastic bottle’s wider part it comes out the bottleneck with higher pressure. As it quickly disperses into the room, its temperature drops.

Sounds uncanny, right? The principle here is quite simple actually. With your mouth wide open, blow some air onto your hand. Does the air feel hot? What if you do the same with pursed lips? Does the air feel cool? That is exactly how the Eco cooler functions!

The thermodynamics here is called theJoule-thomson effect and the process is known as throttling. Liquefiers, refrigerators, heat pumps and air-conditioners work using the same principle.
