Application of passengers’ thermoregulation integral model used in the evaluation of thermal comfort in vehicles compartment equipped with internal curtains

This work evaluates the passengers thermal comfort level inside a vehicles compartment. The numerical study, made in winter conditions, consider bus indoor environment equipped with internal curtains, seats, lateral panels, ceiling, floor and occupied by 52 passengers. model considers vehicle grid generation, body clothing response level. generation is used to evaluate view factors Mean Radiant Temperature that are subjected. In this calculus surfaces shading devices considered. models energy mass balance integral equations. evaluation heat produced exchange between environment. human also thermoregulatory system control temperature. seated subjected asymmetrical warm curtains. Three Cases studies were developed: first one temperature curtains equal surfaces, while other two higher temperatures values. All thermally comfortable according standards.
