<b>Evaluation Method of Passenger Thermal Comfort Considering Effects of Airflow by Cross-flow Fan in Commuter Vehicles in Summer</b>

Abstract

The purpose of this study is to propose a method for evaluating passenger thermal comfort in nonsteady state thermal environments with airflow by cross-flow fans in commuter trains in summer. The proposed method is composed of a human thermoregulation model applicable to non-steady state thermal environments and a statistical model derived from the results of experiments conducted in commuter trains in summer. To evaluate thermal comfort considering the influence of a cyclic wind from cross-flow fans, the proposed method converts the cyclic wind to a constant wind speed equal to the total amount of heat loss from the whole-body calculated by human thermoregulation model. We applied the proposed method to our previous research and confirmed that the observed data and predictions agree well.
