Description

 The object of research is the ventilation system installed at the facility: Civil Defense Building (storage), located in the city of Kryvyi Rih, str. Tsymlyanska, 1, its actual parameters of air consumption and pressure loss. The purpose of the work is to examine the ventilation system of the protective structure of the civil defense (storage) and determine its efficiency, to study the cost characteristics of the ventilation network with the determination of the aerodynamic parameters of the filters of the ventilation system of the protective structure of the civil defense (storage) at the address: Kryvyi Rih, st. Tsymlyanska, 1, compiled based on the results of aerodynamic measurements. Research method. The task is performed by measuring the dynamic pressure or speed of air movement at characteristic points of air ducts, followed by determining the air flow and comparing the obtained flow characteristics with the characteristics of the ventilation equipment. Measurements for this type of ventilation systems are performed for two modes of operation - clean ventilation and filter ventilation, according to the constructive solution of the ventilation system according to the building's passport. The actual measurement results are determined under the nominal operating conditions of the ventilation system and are consistent with the data of the ventilation equipment according to the provided documentation and field surveys, executive schemes. The results of measurements and calculations are presented in tables and diagrams of ventilation systems, comprehensively presented in the materials of the report. Based on the results of the measurements, the compliance of the actual air consumption with the passport data of the ventilation equipment or with permissible deviations is confirmed. The operating parameters of the ventilation filters of the ventilation system are determined separately, with a comparison of the actual results with the passport data.
