How it works

District cooling follows a simple process as illustrated below

  • Water is chilled at a central cooling plant

  • Chilled water is pumped through a network of underground insulated pipes to customers’ buildings

  • An air-conditioning water system inside the customer’s building circulates the chilled water

  • Air is then pumped through the chilled water piping of the air-conditioning system producing cold air

Components of the district cooling system:

  • Central cooling plant

  • Pipe Distribution Network (PDN)

  • Energy Transfer Station (ETS) or customer connection point.
