Using stored snow as cooling at Oslo airport, Norway

Abstract

A state-of-the-art snow cooling system was installed at Oslo airport in Norway in 2016 to reduce the energy costs of its new, bigger terminal building. Based on experiences of pioneering projects in Sweden and Japan, the environmentally friendly system is designed to reduce the summer cooling load by up to 5 MW. This paper describes the design and construction of the innovative snow cooling system and reports on its first 2 years of operation. In 2017 the system saved 375 MWh compared to conventional cooling systems and further improvements are expected over the next 2 years.
