Özet

Environmental parameters affecting the thermal comfort are; air temperature, relative humidity, mean radiant temperature and air velocities on human body segments. At this study, the effects of nonuniform and highly transient thermal comfort parameters were tested experimentally for two ventilation modes (panel vents, windshield and foot vents). With prepared simulation model thermal behavior, physiological reactions (skin temperatures) and thermal sensations of the driver were predicted. In the experiments air temperatures and velocities around the human body segments were measured at I I and 17 different points respectively. Relative humidity measurements were performed from the head region of the driver. In the theoretical studies, dynamic and close loop Matlab-Simulink model of the human body vas developed. In the simulation, the human body separated to 16 body segments to predict local dissatisfactions. The model was justified with the obtained experimental data from the literature.
