description: This work is devoted to the analysis of the influence of additional fans installed on the ventilation system with natural inducement through the use of existing calculation methods in order to identify the optimal technical solution. The tasks that were solved during the study: 1. Analyze the experience of using naturally induced ventilation systems in residential apartment buildings. 2. Develop a simulation model of a naturally induced ventilation system. 3. Analyze the results obtained, draw conclusions and propose solutions for improving and stabilizing the ventilation system on their basis. During the work, an imitation model of an apartment building in St. Petersburg with a supply and exhaust ventilation system with a natural impulse was compiled and a scheme for switching on household exhaust fans depending on the ambient temperature was proposed, which allows increasing the stability of the ventilation system. Also, during the work, the joint simultaneous operation of exhaust fans was calculated. The calculation showed that with the simultaneous operation of the fans in the network, the head of each fan is significantly reduced. Thus, improperly selected exhaust fans can significantly worsen the operation of the entire exhaust ventilation of an apartment building.
