District cooling system: the most efficient system for urban applications.

Author(s) : POEUF P., SENEJEAN B., LADAURADE C.

Summary

The district cooling system (DCS) has many advantages in energy efficiency, resource preservation, environmental impact reduction, urban architecture. Within the framework of the public service since 1991, the Parisian DCS has been developed and today represents 305 MW cooling requirements. The diminution in energy consumption is one of the major concerns for the operator. In the last ten years, the operator undertook changes to its production management in order to reduce electricity consumption and the environmental impact. The results are significant with a reduction of 20% of the specific consumption ratio. The competition with stand-alone chilled water plants drove comparison of the energy performances with the DCS of Paris. An efficiency measurement campaign for independent plants performed over a period of one year shows that stand-alone plant performances are different and lower than the theoretical ones considered for the design and provide the Parisian district cooling system with significant advantages: -47% decrease in electrical consumption and -51% reduction in CO2 emissions.
