Present a mathematical model that includes the Navier -Stokes equations in projections on the axes x, y, z, the continuity equation, energy equation, Poisson equation for the pressure derived from the equations of motion and continuity in the approximation of incompressibility, and a numerical method for the explicit two-step scheme Brailovsky, used in the software package “Locairheat”. As the turbulence model used algebraic model of turbulence Prandtl. An algorithm and an example of the calculation of the thermal control system of air-heating units using the software package. As an example, the calculation is considered calculation of the heating system using a single jet of air-heating units at an inclined feed supply air jets in the shop length 50 m, width of 10 m and a height of 9m.
