Renewable solution for IKEA, Amersfoort, the Netherlands

A new branch of furniture superstore IKEA has been built in Amersfoort in the Netherlands. This new store is being cooled and heated using an underground energy storage system, which has a cooling capacity of approximately 1,900kW.

The principle of cold water storage is that the Amersfoort IKEA branch is cooled in the summer using cold water that has been stored underground during the winter. Under the ground, the cold storage system consists of one cold and one warm well. The two wells are connected by a transport pipe and energy exchange with the building circuit takes place by means of heat exchangers in this pipe. The groundwater does not come into contact with the water in the building circuit.
