District Cooling for the Big City

From the central unit, cool water with a temperature of five degrees Celsius flows through the city via a well-insulated pipeline system. The system cools office buildings, shopping centers, the university, and other public facilities and reabsorbs the heat in these premises. The water, which is thus heated to about twelve degrees Celsius, flows back into the cooling system, and then the cycle starts all over again. All told, the company supplies about 400,000 household and commercial clients in South Saxony with natural gas, electricity, heat, cooling energy, and water.
