AIR REGENERATION SYSTEM Russian patent published in 2012 - IPC A62B11/00 A61L9/00 

FIELD: fire fighting means.

SUBSTANCE: invention is designed for air regeneration systems of civil defense structures during work of the latter in the third mode (isolation mode). The air regeneration system comprises an oxygen generator (OG), a gas-liquid ejector, a central conditioner (CC) with the nozzle chamber. The ejector is connected by the pipeline to the acid generator. The ejector is connected through the pump to another pipeline to supply water from the tray of the nozzle chamber of the central conditioner (CC) to the nozzles. Output of liquid-gas ejector is connected by the pipeline to the nozzle chamber to supply air to the room. The room is connected by the air duct to the device for gas treatment. Output of the device for gas treatment is connected by the air duct to the regenerative cartridge RC-100 for carbon dioxide absorbtion. The output of the RC-100 is connected to the suction pipe of the CC fan. The device for gas treatment is connected by the pipeline to a heat exchanger - the source of coolant (water). The heat exchanger is connected by the pipeline to the evaporator of the chilling machine.

EFFECT: invention provides refilling the oxygen demand in air, as well as absorbs carbon dioxide and purifies air from dust and moisture.
