friendly fridge

 The project by Diveesha Deevela and Anand Shankar from CMR National Public School won first prize at the regional-level science show organised by the Central Board of Secondary Education recently . It was also showcased at the nationallevel exhibition under the `renewable resources' theme last month.


The team used soil, a copper pipe, a funnel, a glass box and a steel box to create an eco-friendly refrigerator based on the principle of evaporative cooling. A suction pipe blows air into a funnel and a copper pipe takes the air through moist soil. “The air becomes cool because moist soil, since ancient times, is used to aid cooling.The air is sent into a glass chamber filled with water, where evaporative cooling takes place. The air inside the copper pipe becomes cooler and dry . The copper pipe is then directed into the storage chamber where fruits and vegetables are stored,“ Shankar explained.
