With Circulation
  • The Requirement -- In cold climates, military personnel need warm shelter for protection from the elements. In tents, sheds, and buildings without central heating, the shelters use individual space heaters to provide warmth.
  • In such uninsulated structures, the hot air from the heaters rapidly rises to the ceiling without warming the actual living space.
  • The comfort level in these shelters is markedly improved if the warm air is directly circulated throughout the shelter, as compared to natural convection conditions.
