Abstract

Due to the fact that the radiation factor has a significant effect on thermal comfort, modeling of radiative heat exchange processes in rooms using the black ball thermometer method is considered. On the basis of the calculated expressions for the temperature of a black ball thermometer, as a function of the mean radiation temperature, generalized dependences are proposed for balls of standard diameters of 150, 120 and 90 mm in the air velocity range 0,1-0,5 m/s. A simulation model of a room with a black ball thermometer, which is verified by the results of the fullscale experiment, is proposed. The simulation model and the graphs of the dependences of the radiation factor indices allow to reliably predict the temperature of the black ball thermometer and, accordingly, the average radiation temperature, which has a significant effect on the thermal comfort in the room.
