Relevance. The article is devoted to the analysis of space heating systems using a light-type gas infrared emitter. For the effective use of these systems, appropriate recommendations for their use are formulated. In this relation the authors carry out a mathematical analysis of the dynamics of changes in time of averaged temperature values by the volume of the room, by the volume of enclosing structures (floor, ceiling, walls), by the volume of the local zone formed by temporary enclosing structures (screens). The temperature regime of the local zone formed by temporary enclosing structures in the form of screens is analyzed. The maximum temperatures of the average temperatures of the room and the local zone are determined for various modes of using the radiant heat flux. Purpose: to analyze methods and ranges for increasing the energy efficiency of heating systems using a high-intensity gas infrared heater. Objects: heating system using high-intensity gas infrared heater. Methods: mathematical model of the process using averaged temperatures over the premise volume, over the volume of enclosing structures (floor, ceiling, walls), experimental determination of the temperature field, mathematical modeling based on a two-dimensional approach. Results. The paper introduces the calculations results of the temperatures average values dynamics of the premise air, enclosing structures and local zone air, the maximum values of temperatures and the dynamics in time of heat flows involved in premise heating. A comparative analysis of the average premise temperature calculations with experimental temperature measurements and numerical simulation in a two-dimensional formulation is given. Based on the results of the analysis, directions for increasing the energy efficiency of heating systems based on gas infrared heater are formulated.
