Mathematical modeling of heat transfer processes in a room with a gas infrared heater, an air exchange system, a horizontal panel simulating equipment, and a local fence has been conducted. The system of equations of radiative heat transfer, energy and Navier—Stokes for air and thermal conductivity for solid elements were solved. The fields of temperatures and air velocities obtained as a result of modeling illustrate the possibility of controlling the thermal regime of a local working area when a special fence is installed at its border. It was found that by changing the height and the material of the fence, it is possible to change the local and average air temperatures of the local working area. The results give grounds for the conclusion that by varying the parameters of local fences, it is possible to create more comfortable temperature conditions in the local working area when gas infrared heaters operate under conditions of intense air exchange.
Keywords: mathematical modeling, thermal regime, gas infrared heater, heat supply object, convective heat transfer. .
