The thermogasdynamic and humidity model was developed using the Ansys CFD software. Verification of the computer model was carried out using experimental data for 2018. Unknown tunnel air flow rates were determined by the computer model parameters identification. When modeling the heat and humidity state of the tunnels, the thermal inertia of the soil layer around the tunnels was taken into account. Simulation of the heat and humidity state of the SIL tunnels during the calendar year showed that a change in the operating modes of ventilation units during the summer period, when air from the environment is pumped into the tunnel and removed from the tunnels by station fans, will reduce the relative humidity below 75 %. The simulation results were confirmed by experimental tests in the Kiev metro and introduced for use throughout the calendar year in the future.
