Studies on Thermal Responses of Sprinkler Heads in Atrium Buildings with Fire Field Models

摘要

Sprinklers are commonly sited in the high headspace atrium of a building where such systems are required. It was questioned whether sprinkler heads would be activated in the case of a fire. A fire modelling technique was applied to estimate the actuation time of sprinkler heads located in the atrium ceiling. The response time of sprinkler heads to a fire in a shop at a high level adjacent to the atrium roof was calculated. A self-developed FORTRAN code together with the CFD model CFX4.2 were used to simulate the atrium fire environment. estimate
