Snow-Based Cooling System


The transport ministry aims to introduce a system in fiscal 2010 to provide 30% of the cooling energy at New Chitose Airport terminal building in summer from snow collected in winter, ministry officials said Tuesday.

A regional office of the Ministry of Land, Infrastructure, Transport and Tourism collected snow last winter at the airport and confirmed that it could retain up to 45% of it by September by covering it with heat-insulating materials. It has concluded that the snow could be used to chill the liquid used in the airport’s cooling system in summer and that doing so would lead to a cut of some 2,100 tons of carbon dioxide emissions annually, according to the officials.
