LA-80-04-3 -- Stairwell Pressurization
Pressurized stairwells have been used increasingly in the past few years to provide smoke free escape routes. However, there are no accepted design procedures for these systems. This paper provides a discussion of several of the designs currently in use. In particular, single and multiple inject.ion systems are discussed. A report is made on field tests on 5 pressurized stairwells. The testing is part of a continuous program to evaluate alternate systems, in an attempt to establish design recommendations for the future.Citation: ASHRAE Transactions, Volume 86, Part 1, Los Angeles, California
