The City of Gothenburg in Sweden uses a district cooling system powered by the cool flows from the river Göta älv.
Gothenburg, Sweden, uses the river Göta älv to pre-cool water used in its large-scale district cooling system. By using a combination of river water for pre-cooling and waste heat from an incineration plant to drive its absorption chillers, Gothenburg substantially lowered CO2 emissions compared to conventional cooling methods. Customers get the environmental benefit of sustainable cooling at an affordable cost.
