As well as in buildings, HVAC is an important system that significantly influences energy performance and thermal comfort in vehicles. The thermal comfort indices developed for homogeneous indoors could not be applied to the inhomogeneous thermal environment of vehicles. Several human thermal physiological models have been developed to simulate transient and local inhomogeneities in the thermal environment. In this study, specific convective heat transfer coefficients of human body segments were measured through experiments in a chamber to develop a human thermal physiological model that can be used for vehicles. It is confirmed from the experiments that the convective heat transfers are significantly varied with human body segments under HVAC fan operation because of air velocity. The convective heat transfer on the subject segments ranged from 41.0 to 145.6 W/m2 and from 51.7 to 118.7 W/m2 for the second and seventh fan speeds, respectively. The model for convective heat transfer coefficients of each segment was proposed to predict the convective heat transfer in the human body. The model and results of this study could help evaluate the inhomogeneous thermal environment, and also design HVAC systems for vehicles.
