  • The present Invention relates to an overpressure-based system applied to protect vertical evacuation routes against smoke infiltration. The Invention makes it possible to limit or to fully eliminate the phenomenon of thermal draught that occurs, particularly intensely, in staircases of high or high-rise buildings. Moreover, the system according to this Invention can be used in the objects such as hospitals or laboratories, where it is necessary to accurately maintain the pressure difference between two zones on a preset level (e.g. room-room; room-air supply/return air duct).
  • A phenomenon of thermal draught occurring in high and high-rise buildings depends on a temperature difference in the external and internal space of those buildings. In the hitherto systems, a multi-inlet system of air blowing was utilized, with air inlets arranged evenly along the vertical line of staircases; however, this system has not overcome the thermal draught phenomenon. The commonly known systems of controlling pressures function on the basis of air bleed flaps and multi-inlet system of air blowing.
  • The purpose of this Invention is to eliminate the thermal draught phenomenon occurring while admitting air into vertical evacuation routes. Additionally, this Invention aims solving the issue of controlling air admission into vertical evacuation routes and at making it possible to quickly change volumetric flow of air and to maintain various levels of preset air pressure. This Invention solves the problem of maintaining a required overpressure level of 50 Pa+/−10% within the entire vertical evacuation route. −/−
