Two students of the Indian Institute of Technology (IIT), Roorkee, have devised a new room-cooling solution“Evacool” that has won Schneider Electric’s global ‘Go Green in the City 2017’ contest, which was held in Paris.
This creation is based on evaporative cooling,that is, when evaporation takes place, it cools the surface and the temperature of air around it cools as well.
The creator Nimisha Gupta and Raja Jain took inspiration from “ghada” (earthen pots) to cool down your rooms efficiently and without adding any carbon footprint.
According to them, the machine, which will use cylindrical baked clay ducts along with an air source and a water source, can cool an average room by 10 degree Celsius. It will cost ₹4,000, making it an affordable cooling solution for the mass market. It uses only 65-100 W of electricity per hour (equivalent to a fan). Besides, over its entire life-cycle, Evacool produces 96 per cent less greenhouse gases than an air-conditioner.
Jain and Gupta have been at this project for over six months and hope to market their product soon.
“Once we are done with the research and development and get the patent, Evacool will soon enter the market,” Jain said.
The initiative received an overwhelming response from across the globe, with 19,772 applications from 180 countries.
