Book Description
The punkah proved to be an effective air moving device when it was placed so that it complemented the effect of any thermal force that was present. The Package Ventilation Kit also proved to be an effective means for moving air through a shelter that had no windows and utilized existing doorways as ventilation openings. During the natural ventilation test the effective temperature of the ambient air and shelter air never went above 85DGF ET. Usually the average shelter ET was about 5DGF above the average ambient ET for the same period. The ventilation rate ranged from 10 cfm/person to 26.5 cfm/person indicating that natural ventilation may be adequate for most aboveground fallout shelters with windows.
