We provided numerical analysis using Computational Fluid Dynamics tools to find out the effects of the systems interaction in representative car park building and different configuration of smoke control systems. We conducted the qualitative and quantitative research to obtain the patterns and times of the sprinklers activation. We analysed the influence of Smoke Control System on the effectiveness of the Sprinkler System. As a results of the research we created general conclusions which can be used as a set of guidelines during designing process. Moreover some results can encourage other scientists for further numerical analysis or real scale tests.

Fire Door

In the event of a fire in a building equipped with air-pressure smoke-control equipment, if the smoke-control system is operated with a closed fire door, then the smoke discharge results in difficulty in opening the door. In this study, an optimal solution was devised to solve the problem of negative pressure generation in building corridors, and the proposed solution was verified using CONTAMW, a numerical analysis program for smoke-retardant facilities. Thus, it was confirmed that negative pressure in a corridor could be resolved by installing flap and automotive pressure dampers between the corridor and annex.

A smoke exhaust system must be installed basically in all high-rise buildings in Japan, in order to eliminate smoke and gas from combustible materials and ensure safe evacuation effectively. However, a new problem, i.e., the difficulty of opening and closing doors when a smoke exhaust fan is operating, has occurred since air-tightness has been improved in high-rise buildings. There are therefore many cases recently where a pressurized smoke control system is adopted. In this paper, the basic concept of this system is described and the pressurized smoke control system that is used in Harumi Triton Square, one of the largest high-rise buildings in Japan.
