| Title of the article | Development of the operation mode of the smoke ventilation system in the inter-apartment corridor |
| Abstract. | The relevance of the research is due to the intensive development of high-rise construction. The traditional design of smoke ventilation often does not take into account the dynamics of the fire and the interaction of smoke extraction and compensation systems. According to the Ministry of Emergency Situations of Russia over a 5-year period, 68% of fires in apartment buildings are accompanied by critical smoke on evacuation routes, especially in buildings with open-plan layouts. Problem statement. The study is aimed at evaluating the effectiveness of solutions for smoke ventilation systems in conditions of fire development using the example of a 26-storey residential complex. The purpose is to analyze the interaction of smoke extraction and air compensation systems in inter-apartment corridors at the stage of fire power growth and to develop a methodology for evaluating the effectiveness of fire control during its unsteady development. Research objectives: based on a normative methodology, calculate the power of the fire source and the growing oxygen consumption, taking into account the parameters of the room and the fire load. The mass and volume consumption of the burning products being removed, their temperature and density were determined. The development time of the fire source (30 minutes to peak power) and the flame spread have been calculated. Results show, that smoke ventilation systems that provide a volumetric balance between the removal of the smoke and gas mixture and the supply of compensation air prevent excessive underpressure at the doors (pressure drop 150 Pa). In 30 minutes, the fire load burns out by 50%, while the volume of compensation air does not exceed critical values capable of stimulating the development of the fire. Conclusions. A calculated approach to the design of smoke ventilation, which ensures a volumetric balance, increases the safety of evacuation and complies with regulatory requirements. The results are relevant for apartment buildings, where the correct operation of systems is critical to minimize risks. The study confirms the need to take into account the dynamics of fire and the interaction of ventilation systems. |
