摘要：
The results of experimental studies and of mathematical simulation of heat transfer processes in a room with an air exchange system and an operating gas infrared radiator are presented. Temperatures were recorded in the local working area, in which a horizontal panel simulating equipment is located. The regimes of mixed convection for variants with different emissivities were studied, and their influence on the formation temperature fields and the creation of comfortable conditions was established. It was found that the regulational thermal regime can be achieved by increasing the emissivity and reducing the thermal conductivity coefficient of the materials of the floor surface sections situated in local working areas.
