Proof of Concept: Firn Air Facility Cooling at Summit Station, Greenland


A firn air cooling system that utilized the natural reservoir of cool air at depth in polar ice sheets was tested at Summit Station, Greenland during the summer of 2010. Cooling is required on station to meet the requirements for food safety and scientific core storage. Firn air cooling is a potential replacement for traditional mechanical cooling systems. The system design, installation, and results of several experiments are presented. The system cooled a 27m3 enclosed, insulated structure from 20 to 25°C using a 10-m borehole and a fan pumping the naturally cool air. The system was easy to install in a short time frame and was low cost from an equipment and operating perspective.
