The head of Danfoss India says the company is targeting district cooling as one means of making the country’s cities more energy efficient.

Danfoss India President P. Ravichandran told the Hindu newspaper that the technology can help reduce efficiencies lost in urban air conditioning.

“When you look at commercial air conditioning, it consumes 30-40 per cent of the energy that is needed to cool the building. So on one side we need 83 GW of power in the next six years. On the other side, you have a peculiar problem where we have huge swings in air conditioning.”

“Commercial air conditioning is costly now but with energy efficient technology it costs 20 per cent lesser. More than the cost, it cuts down carbon footprint.”

Ravichandran said that energy consumption in cities is an obvious target, with cities account ting for 70 per cent of the GDP. Cities are also the culprit for the peak load of 40 per cent when the cooling loads go up.

District cooling can work well in an Indian urban setting, he said.

“In a gated community with 3,000 houses, you don’t need an AC for each room. District cooling circulates cold air like how electricity flows in a pipe. Cold air flows in a pipe. So you only fit the indoor equipment and use the cold air for air conditioning purposes. That technology offers another 30-40 per cent savings for the air conditioning load. This is also one of the technologies that the World Energy Forum has suggested as one of the 10 most disruptive technologies for the future.”

Danfoss have identified cities like Rajkot, Pune, Thane, Bhopal and Coimbatore for implementing district cooling.
