Fluid flow numerical simulations, which allow to modeling the real operating conditions of large-scale industrial installations, make possible to conduct risk analysis and multi-variant parametrical economic and technological optimization, to select the most favorable variant for investment at the design stage. The article presents the prepared conceptual design of the HVAC installation for a production hall with an area of 25 m x 10 m. Based on the set design assumptions, a 3D model of the hall was created along with the arrangement of supply and exhaust ducts and fan heaters, whose operation should ensure proper thermal comfort in the indoors. Mathematical model and numerical CFD model were created to verify the influence of power of fan heaters on the velocity and temperature contours in the production hall. The obtained results made it possible to determine temperature and velocity profiles in the people’s zone, and the adopted research methodology allowed to analyze the impact of the operation of fan
heaters on the conditions in the production hall.
