Résumé

One of the aims that the manufacturers of modern vehicles have in mind is the development of new and optimization of the existing systems for achieving and maintaining thermal comfort in the passenger area. Without correct selection and sizing of the HVAC system for passenger area, there is no thermal comfort. For the computerized evaluation of thermal comfort on the selected two seats the 4 following measured variables are used: air speed, humidity, air temperature and the temperature of the black ball. In addition to the prediction regarding the percentage of unsatisfied persons during the cool-down phase of the vehicle interior, the special thermal characteristics in the vehicle are pointed out. Within the scope of the work the thermal comfort of the inhomogeneous is compared with the homogeneous environment. Using the operational and the equivalent temperature according to SAE J2234 the homogeneous environments are determined. On the seat-plan the same transformation of energy per person as well as the same clothing are accepted. The following external conditions are constant; incident-flow velocity of the vehicle, air temperature and humidity. The aim of the paper is to indicate a complexity of determining the thermal comfort conditions in passenger vehicles.
