With rising temperatures, prolonged heatwaves and increasing air conditioner use, experts are advocating district cooling systems as an energy efficient solution aligned with India’s climate and urban planning goals.
What is District Cooling?
- A centralised cooling system that supplies chilled water from one large plant to multiple buildings through insulated underground pipes.
- Instead of each building installing separate chillers:
- A central plant produces chilled water at 6 to 7°C.
- Water circulates to buildings and absorbs indoor heat.
- Returns at 12 to 14°C to be cooled again.
- It works like a public utility similar to piped gas or electricity.
