Water Leakage of Elevator Doors With Application to Building Fire Suppression

摘要

The project focuses on water flow rates into elevator hoistways (elevator shafts)and the flow paths in the hoistways with the intent of providing information that might be useful to industry in dealing with this issue. This paper describes a series of laboratory tests to: (1) determine typical flow rates of water through elevator doors, (2) observe water leakage patterns, (3) evaluate the performance of modified door gibs and brackets intended to reduce or redirect water leakage, and (3) evaluate a test enclosure concept for possible field testing.
