Automotive engineers have been required to satisfy passengers’ thermal comfort with minimum energy as well as reduce fuel consumption of vehicles. To satisfy human conditioning with minimum energy, not only improving efficiency of air conditioning with HVAC(Heating, Ventilating and Air Conditioning) but also using another efficient devices is considered. The devices provide a passenger with heat or cold directly by conduction and radiation. As a result, the total energy can be reduced comparing with convectional HVAC system. When the devices are combined to conventional HVAC system, performance of front HVAC can be reduced based on maintaining thermal comfort. In order to contribute to the investigation, a evaluation method of thermal comfort is required in consideration of convection, conduction and radiation. For constructing this evaluation method, a human thermal model, that was divided some partial body parts of human, was developed to evaluate the environment in a passenger compartment. Heat quatity from blood to each segment and heat storage were calculated by thermoregulatory function in the human thermal model. In order to evaluate partial-body thermal sensation, the partial-body standard new effective temperatures (SET*) was calculated by using the human thermal model based on air and radiant temperature, air-flow velocity and humidity in a passenger compartment, that were measured by using an amenity manikin. Partial body thermal sensations were evaluated by the local SET*, heat quantity from blood flow and heat storage. Distribution of the partial-body thermal sensation and whole body thermal comfort were founded to be mutually related. Based on the relation, whole body thermal sensation was evaluated by partial-body thermal sensation. This paper describes detail of the methodology and introduces examples of evaluation.
