Методология выбора варианта конструктивного устройства АУП в высокостеллажных складах

В статье рассмотрены вопросы вариантного проектирования автоматических установок водяного пожаротушения в высокостеллажных складах хранения тарных грузов: с одноярусным и многоярусным расположением оросителей. Предложена методология выбора экономически обоснованного варианта защиты на основе критерия приведенных затрат. Сформулированы требования к минимально необходимому информационному обеспечению задачи. Приведены новые оценки эффективности тушения или локализации пожара системами АУП. The relevance of developing calculation methods to justify the selection of protection options for automatic fire extinguishing systems in a high-rise rack warehouse — either with a single-tier arrangement of high-performance sprinklers under the ceiling or with a multi-tier arrangement — is determined by considerations of economic efficiency and feasibility. At the same time, ensuring the safety of people in a high-rise rack warehouse must be unconditionally prioritized. The authors propose using the criterion of reduced costs to select the optimal fire protection option for a high-rise rack warehouse. The value of this criterion should decrease when transitioning from a system with a multi-tiered sprinkler arrangement to one with a single-tiered configuration. The information support for the methodology described in the article includes the following data: • projected direct fire damage in the warehouse; • fire damage during successful extinguishment (localization) of the fire for both sprinkler arrangements; • capital and operational expenses; • probabilities of successful extinguishment (localization) in a high-rise rack warehouse with single-tier and multi-tier sprinkler systems. The article presents a methodology for quantitatively substantiating (verifying the feasibility) of implementing a single-tier automatic fire extinguishing system in a high-rise rack warehouse compared to a multi-tier system. The proposed methodology enables designers, based on variant analysis and specific criteria, to determine the optimal configuration for an automatic fire suppression system in a high-rise rack warehouse storing hazardous materials. This variant design methodology allows evaluating automatic fire sprinkler system options in high-rise rack warehouses from multiple perspectives: risk of fire damage; probabilistic reliability and effectiveness of fire suppression; capital and operational fire protection costs and also helps establish the most economically viable design solution for automatic fire extinguishing systems.
