IMPROVING THE EFFICIENCY OF FIRE EXTINGUISHING INSTALLATIONS BY SELECTING THE PREFERRED TYPE OF COMPRESSOR USING THE HIERARCHY ANALYSIS METHOD

Fire extinguishing installations are a complex system with many elements, the main of which are containers for extinguishing agents, gas cylinders, an internal combustion engine, a fire centrifugal pump, a compressor, shut-off valves, etc. The paper presents data on the selection of the most preferred type of compressor, which plays a major role in the displacement of extinguishing agents from fire extinguishing installations. The right choice of compressor, in our opinion, leads to more efficient and stable operation of the entire installation. In this regard, there is a need to conduct a comparative assessment of the types of compressors existing in the industry according to their totality. For this purpose, a hierarchical structure of a multi-criteria assessment has been built, with the help of which the most preferred type of compressor is determined. Actions are proposed for further investigation of the process of displacement of fire extinguishing agent from fire extinguishing installations.
