Abstract

The effectiveness of mechanical tactical ventilation during rescue and firefighting operations can be improved by multiplying the number of positive pressure ventilators. Such action can shorten the time of the operation, improve its execution, and reduce the energy consumed by the ventilators used during the operation. In order to determine the proper conditions for the two ventilators to work together, tests were conducted on their positioning relative to the doorway. These values were determined from the flow parameters (flow rate and static overpressure generated). A set of conventional rotor ventilators (each with an output of 4.4 kW) was tested. The article performs an analysis of the magnitude of flow parameters depending on the setting of the positive pressure ventilator. Proper positioning of the set of ventilators can increase the flow rate through the facility by up to 32% and the pressure by 50%. The analysis conducted in the article can be used as recommendations for rescue teams for the proper selection of the setting of the positive pressure ventilator during firefighting operations of internal fires.
