A review of methods for calculating microclimate parameters is performed. The possibility of using existing mathematical models to describe the aerodynamic characteristics of ventilation valves and optimize their performance indicators: productivity, hydraulic resistance, density, response time and other parameters that form their efficiency is considered. In order to assess the correspondence of the obtained mathematical dependencies, a physical experiment was conducted. The adequacy of the mathematical model was verified by comparing the results of calculating the parameters of the internal environment in the SolidWorks software and computing complex with experimental data.
