IISc develops clean, green cooling tech for Indian Navy

Bengaluru: Indian Navy will soon have a clean, green cooling technology using carbon dioxide (CO2) as a team of seven scientists and researchers from Indian Institute of Science (IISc) has developed the technological innovation.

The team from the Interdisciplinary Centre for Energy Research (ICER), IISc, developed a transcritical CO2-based refrigeration and heat pump system. The system has completed 1,300 hours of testing at Maharashtra-based naval base INS Shivaji. It will be officially inaugurated by the Navy this month.

Elaborating on the refrigeration system, the researchers at ICER, told that Current refrigeration systems use synthetic chemicals such as HFCs and HFOs for cooling. These synthetic refrigerants emit significant greenhouse gas emissions.

The Navy wanted to be the first in India to introduce a green technology for cooling which is compact and best suited for its ships and submarines. It approached IISc for a unique room cooling system using CO2, which is reliable, robust and provides stable cooling, and at the same time can also be used for heating.”
