Bangladesh Grey Dhaka and Grameen Intel Business Social Ltd. developed an air cooling system without electricity called Eco-Cooler, made of plastic bottles as an air conditioning method for low-budget homes that cannot install an air conditioning system and must withstand the high temperatures of some South Asian countries.
The researchers built the Eco-Cooler using soft drinks and plastic water bottles, which helps reduce temperatures in tin huts so they are bearable to live in. Villagers were trained on how to make the Eco-Coolers themselves using the plastic raw materials of beverages and soft water bottles that are readily available due to the lack of recycling facilities.
Eco-Coolers were installed in the tin huts based on wind direction and airflow pressure t, decreasing the temperature to 5 ° C. At a press briefing, Grameen Intel Business Social Ltd. Deputy General Manager Abdullah Al Mamun said, "As most rural houses in Bangladesh are made of corrugated metal sheets, the Eco-Cooler has the power to provide relief to millions of Bangladeshis. We hope this volunteer effort will make a difference in their lives."
The Eco-Cooler uses a grid made of plastic bottles cut in half, which can be placed on the windows. Hot air enters the open end of the bottle and is compressed into the neck of the bottle, so it is colder before it passes into the room.
