District Cooling SystemDistrict Cooling System District cooling indicates the central District cooling indicates the central manufacturing and distribution of manufacturing and distribution of

cooling energy. Chilled water is provided cooling energy. Chilled water is provided by means of an underground insulated by means of an underground insulated pipeline to office, commercial as well as pipeline to office, commercial as well as household structures to cool down the household structures to cool down the

interior air of the buildings within a interior air of the buildings within a district. Specifically designed devices in district. Specifically designed devices in

District cooling systems, are included District cooling systems, are included collective tools to produce and distribute collective tools to produce and distribute chilled water. Chilled water is produced chilled water. Chilled water is produced

by production plants as well as dispersed by production plants as well as dispersed by water pipes (the distribution network) by water pipes (the distribution network)
