ANALYSIS OF ABOVEGROUND FALLOUT SHELTER VENTILATION REQUIREMENTS

Abstract

Transient and steady analysis are used to determine the psychrometric conditions that develop in large aboveground fallout shelters ventilated with unconditioned ambient air. These analyses consider the shelter size, geometry and construction, the psychrometric condition of the ambient weather, and the various metabolic and nonmetabolic heat loads to the shelter air. The results of this study indicate that during the hot summer weather, only a small fraction of the total energy input to the shelter is lost through the shelter boundary surfaces. Thus, the ventilation requirements for large aboveground shelters can be obtained by the use of an analysis which neglects the heat loss through the shelter boundaries. This means that aboveground shelter ventilation systems should be designed to remove the entire thermal load generated within the shelter.
