TUNNEL COOLING FOR BYRD STATION, ANTARCTICA-1969 PROGRESS REVIEW.
Byrd Station is located in snow tunnels more than 20 feet below the surface of the antarctic continental ice cap. The accumulation of heat lost from the buildings and other facilities in the tunnels and summer surface air temperatures to plus 25F necessitates supplementary air cooling, to maintain t...
