With the support of EDF’s R&D Center in China, EDF proposes a multi-energy system which innovatively integrates and optimizes different types of cooling. In addition to the use of high performance chillers, the cold is also stored in the ice overnight when there is low demand for air-conditioning and the cost of electricity is less expensive. The heat released when generating cold is recovered for the supply of sanitary hot water to the local hotels.
This project contributes to supporting low-carbon development of the city. Compared to using individual and isolated systems, the network will reduce CO2 emission by 20% when completed, equivalent to 70,000 tons less of CO2 each year.
In the future, this project also plans to integrate photovoltaic panels into the district energy network. The tri-generation system, with the simultaneous generation of ice water, hot water and electricity, will maximize the overall efficiency of the installation.
