This work is devoted to the study of gas-dynamic processes in operation climate control systems cabins vehicles (HVAC), focusing on pressure values. research examines issue assessing required values air overpressure inside locomotive cabin, which necessary prevent gas exchange between interior cabin and outside through leaks including protection against penetration harmful substances. The boost depends, among other things, external body, power system fan, ratio input output deflectors. To determine pressure, problem train movement a wind tunnel considered, internal fluids domain skin determined using numerical methods CFD based Navier–Stokes equations, depending speed movement. finite-volume modeling package Ansys (Fluent) was used as an implementation. excess ensures under different operating modes, were studied numerically basis approximate applied formula. In particular, studies carried out transport, airflow system, areas parameters. During experiment, it found that for 100 km/h, 560 kPa, most energy-efficient way increase regulate area outlet valves.
