The present invention relates to a fire evacuation room that provides a space installed indoors in a high-rise building such as an apartment block so as to provide a person who is unable to escape outside with a space in which to safely take refuge. The present invention can be installed indoors in an apartment or in a basement of a building as desired so as to enable a person unable to evacuate outside the building to safely evacuate, wherein a predetermined pressure differential can be constantly produced by suitably controlling the amount of air entering the evacuation space and the amount of air leaving the evacuation space, thereby compensating for the occurrence of leaks inside the evacuation space by damage due to falling objects and the like, and thus a fire evacuation room can be provided that completely mitigates a shortage of air for breathing. Furthermore, the present invention can provide a fire evacuation room that can improve the overall efficiency of the system for air provision by unified operation of the air supply for each fire evacuation room installed on each story of a building by connecting the various air intake pipes to pipes of the ventilation system of the building or to separate pipes of the blower equipment inside the building. In addition, an air forced discharge fan which is installed in the interior wall surface inside the evacuation space is linked in operation to opening and closing of a door so as to actuate the air forced discharge fan, so as to be able to forcibly discharge air inside the evacuation space when the door is open and consequently, the evacuation space is able to block the entry of smoke or heat to the inside from the outside. In addition, the present invention provides a fire evacuation room wherein a branch pipe is formed on one side of an air intake pipe through which air flows into the inside of the evacuation room main body, and a filter device capable of purifying toxic gas such as smoke, in addition to oxygen generator that generates oxygen, is installed on the branch pipe so as to block the entry of external toxic gas while simultaneously supplying air to the inside of the evacuation room main body for evacuees to breathe, or by operating an air storage tank by utilizing the frame space of the evacuation room main body, so as to implement a new system that supplies air into the inside of the evacuation room main body for evacuees to breathe, thereby completely eliminating such problems as toxic gas flowing inside the fire evacuation room and protecting the safety of evacuees to the maximum.

Disclosed are methods and a safety system implemented within a structure of automatic modification of a rate of filling an air bottle with breathable air in the safety system. In accordance therewith, an air fill charge rate controller device is coupled to the breathable air from a source thereof in the safety system having a fixed piping system installed within the structure for supply of the breathable air across the safety system. A flow rate of the breathable air from the source thereof is detected through a flow sensor associated with the air fill charge rate controller device. In accordance with the detection of the flow rate, a control unit of the air fill charge rate controller device automatically modifies a fill rate at which the air bottle is to be filled with the breathable air.
