VENTILATION TESTS OF FALLOUT SHELTER SPACES IN NEW YORK CITY AND VICINITY
Abstract
Natural and forced ventilation tests were conducted during 1964 at eight shelter sites. Included were: three (summer) tests in high-rise building core areas; two (summer) tests in public school corridors and basements; one (summer) test in a home basement; one (summer) test in a buried community shelter; one (winter) test in a buried private shelter. Using electro- mechanical 'Simocs' to simulate shelter occupancy, the resulting physical environment was measured and analyzed. Manual ventilation devices and water- cooled heat exchangers were developed and tested to determine their ability to provide a more tolerable shelter environment. Formulas for predicting shelter ventilation and temperatures are discussed. Methods for improving ventilation rate are suggested. The report concludes that effective temperature (ET) in naturally ventilated above-ground shelters (loading: one person/10 sq. ft.) will not exceed 85F with outside air at N.Y.C. 15% summer design level. In naturally ventilated buried or semi-buried shelters (one person/10 sq. ft.), ET may exceed 85F at same design level. During normal winter weather (Conn.), naturally ventilated underground shelters with efficient heat sinks will have uncomfortably low ET (40F-50F), if loaded with fewer than one person/10 sq. ft. Radiant reflective insulating paper is found to increase ET by 10-15F while preserving the heat sink.
