AbstractThe material in this paper is part of a joint project between the United States and Canada to evaluate the feasibility of elevator evacuation of the handicapped. This paper presents an analysis for the pressure differences produced by elevator car motion and it presents flow coefficients for flow around cars in elevator shafts based on test data. The results of an experiment to verify this piston effect analysis are presented. Also, practical considerations concerning piston effect and elevator smoke control are presented. An equation is developed to determine the upper limit of the pressure difference across an elevator lobby caused by piston effect.
