The cooling is centrally produced and distributed as cold water to each building through a closed distribution net. The system provides flexibility and convenience, allowing each building to adjust its cooling needs without worrying about the size or capacity of individual cooling units The system’s energy efficiency lies in the alfa laval plate heat exchanger, which transfers nearly all the cooling energy to the building with minimal loss. District cooling is a promising option to harness free cooling from sea water and air It can efficiently cool entire communities from a centralized chiller plant and provide free cooling to large geographical areas. By centralizing cooling services, it optimizes energy use while eliminating the need for individual electrical chillers in buildings.
Each building is served by a fully automated intelligent delivery substation, which is connected to a network of six district cooling plants All six plants are located underground, and three of them use water taken directly from the river seine. Alfa laval has been the front runner in developing plate heat exchangers suitable for demanding conditions in district cooling installations The close temperature approach of alfa laval gasketed plate heat exchangers maximizes efficiency, so minimal energy is lost during heat transfer.
