Such ice cores trap gases, bits of dust, and other chemicals that were present in the snow that fell over Greenland for thousands of years and then became compressed into ice.
Most of the population, however, will be undisturbed for only three years, and then they will be dug up, washed, compressed into a small tin box, and placed in a bone room.
Meanwhile, its place is taken by hotter intergalactic gas from farther out on the edge of the galaxy, which cools as it is compressed and flows into the galaxy.
The model includes sub models for key components, such as non economized compressor, economized compressor, economizer, expansion valve, shell and tube condenser, and flooded evaporator.
