The arrangement of protective structures of civil defense is currently vitally important, especially for populated areas located near the combat zone. A pressing issue in the design of shelters is the correct determination of the volumes of air exchanges required to ensure the stay of those sheltered during the standard periods. An analysis of changes in climate and microclimate parameters over the past years and methods for calculating air exchange in protective structures was conducted. A classic model of the process of changing the temperature and humidity of the air with a variable coefficient of inclination of the beam of such a process was built. The redundancy of air exchanges calculated according to the data and methods of the latest regulatory document is shown, leading to an increase in capital costs for the arrangement of a shelter.
