In its simplest form, district cooling is the production and distribution of chilled water from a central source to multiple buildings to facilitate air-conditioning. This is done by producing chilled water at a central plant and then piping the water, through underground insulated pipes, to customers. The main benefits of district cooling are reduced energy and maintenance costs because the buildings that employ it eliminate the need for expensive and noisy rooftop air-conditioning chillers.

District cooling is suitable for residential, commercial and military developments, especially large-scale, high density population developments in cities

How does it work?

• A central plant chills water and then distributes it through an underground insulated pipe network to a customer’s building
• A water circuit in the customer’s building circulates the cold water
• Both networks are closed circuits and the cooling is passed through the energy transfer system
• Air is then forced past the cold water tubing in the customer’s building to produce an A/C environment
• The warmer water is returned to the central plant to be re-chilled and recycled.
