District Cooling should come to Colombo and will Reduce power consumption of Air Conditioners in Colombo. It will give jobs to our country men and women.
District Cooling Overview
District cooling is an essential utility for sustainable economic and urban development.
In its simplest form, district cooling is the production and distribution of chilled water from a central source to facilitate air conditioning. This is done by producing chilled water at a central plant and then piping the water to customers through an underground insulated pipes network.
District cooling is suitable for large-scale, high density developments such as downtown business districts, airports, military bases, university campuses, residential towers and commercial establishments.
Depending on availability, district cooling plants can utilize a variety of conventional fuels such as coal, oil or natural gas. They can also be converted to use renewable fuels such as biomass, geothermal, and combined heat and power.
District Cooling is a simple process:
District cooling is a superior alternative to conventional air conditioning as it helps reduce energy consumption and costs to both customers and governments alike, while also protecting the environment by cutting carbon dioxide emissions. Some of the advantages district cooling has over traditional air conditioning include:

District Cooling is a simple process:
- A central plant chills water
- A primary water circuit then distributes the chilled water to customers' buildings through an underground insulated pipes network
- A secondary water circuit in the customers' building circulates the cold water
- Air is then forced past the cold water tubing to produce an A/C environment
- The warmer water of the primary circuit is returned to the central plant to be re-chilled and recycled
District cooling is a superior alternative to conventional air conditioning as it helps reduce energy consumption and costs to both customers and governments alike, while also protecting the environment by cutting carbon dioxide emissions. Some of the advantages district cooling has over traditional air conditioning include:
- 50% less energy consumption
- Decreases initial capital investment and spreads costs over a longer period of time
- Annual maintenance costs are substantially lower
- Can store up to 30% of potential output by holding chilled water in reserve, therefore easily meeting demands in seasonal variations
- Equipment needs to be replaced only every 30 years – as compared to 15 years for traditional air conditioning
- Greater reliability due to the high standard, industrial equipment utilized and back-up chillers on stand-by
- Protects the environment by reducing CO2 emissions due to lower energy consumption
- District cooling systems are remotely located and therefore enhance real estate value by freeing up space for other uses
