The Eco-Cooler is a revolutionary, eco-friendly air conditioning system that uses zero electricity, making it perfect for homes, especially in areas with limited access to electricity. This innovative system was developed in Bangladesh, one of the world’s poorest countries heavily affected by global warming ¹.

How it Works:

The Eco-Cooler utilizes recycled plastic bottles, cut in half and attached to a board or grille, which is then installed in a window frame. As hot air enters the bottles, it gets compressed while passing through the bottleneck, cooling down before dispersing into the room. This process leverages the Joule-Thomson effect, where gases cool when they expand and heat when compressed.

Key Benefits:

• No Electricity Required: The Eco-Cooler is a sustainable and cost-effective solution for cooling homes.
• Eco-Friendly: Made from recycled plastic bottles, it promotes waste reduction and environmental conservation.
• Accessible: The blueprint for this DIY domestic cooling device is available online, allowing anyone to create their own Eco-Cooler.
• Effective: The Eco-Cooler can reduce temperatures by up to 5°C, comparable to traditional electric air conditioners ² ¹ ³.

Applications:

• Rural Areas: Perfect for areas with limited access to electricity.
• Small Cottages and Huts: Can be fixed in portable tents or small homes.
• Environmental Sustainability: A great solution for those looking to reduce their carbon footprint ³.
