District Cooling: A system in which cold water from a central cold source is distributed through a network of insulated underground pipes to areas requiring cooling for air conditioning. In this network, one unit (investor) provides services to many customers for cooling.

Each year, District Cooling grows 57% in new construction projects. Over the past 4 years, more than 658 million ft² (~61 million m²) of District Cooling  space has been added in the US and Middle East alone. Equivalent to the space of 237 Empire State buildings.

1. District Cooling System:

Cold water is generated by chillers located in the central area.
Pumps are used to circulate cold water to surrounding buildings.
Through heat exchangers, cold water is supplied centrally to reduce the temperature of the secondary cold loop (closed loop) in the building.
Cold water returns to the water chiller location for cooling and circulation.

2. Areas where District Cooling is often installed:

Areas with high population density
Airport
University
Construction clusters
Medical Center
Industry zones
