DISTRICT COOLING SYSTEM (DCS)

What is DCS? Large in scale

centralized cooling system

distributes cooling capacity from a central source to multiple buildings for the cooling purpose of the air-conditioning system

through underground chilled water pipe network

Water-cooled(seawater or fresh water)

Different forms of cooling capacity(usually chilled water)

Mechanism of DCS

Produce cooling capacity in the form of chilled water or other

medium

distributes the cooling capacity (chilled water)

to user buildings through

underground pipes

process cooling for for air-

conditioning purpose at each heat exchanger

in individual building
