ABSTRACT
Vehicular fuel consumption and its environmental impact can be reduced significantly
with advanced climate control systems that intelligently deliver conditioned air, and use more efficient diffusion. However, there is a continuing need developing thermal
comfort models and evaluation methods for these systems. The objective of this study was to investigate the thermal comfort inside the vehicle, analyzing the airflow around thermal manikins and evaluating thermal comfort indices. Two thermal manikins were used to evaluate thermal comfort inside a vehicle. We simulate two passengers and their interaction with the environment. The temperature of the manikins is controlled, generating a thermal plume similar of the passengers inside the cabin. Velocity and temperature measurements help evaluating the indoor air quality and airflow, allowing to evaluate the thermal comfort index: PMV. Comparison with personal thermal comfort assessment was completed. The results permit the evaluation of indoor thermal comfort and the discrepancy in application of standard thermal comfort indices, unadapted to transient conditions as found in the vehicles.
