The airflow velocity in clothing (AVC) was measured by using the bi-directional airflow sensor in order to observe the chimney effect and the pumping effect. Eight female participants were asked to wear a separate type raincoat and they kept themselves in a stationary state or performed the rhythmic work. The climatic chamber was controlled at 23℃ or 18℃ (RH50% ). The AVC caused by chimney effect was higher at 18℃ than at 23℃ significantly. The highest value (0.43m/sec) was observed at the chest area. The pumping effect triggered by the rhythmic work caused the air in clothing flowed from the trunk towards the cuff or the hem of a raincoat and overwhelmed the chimney effect.
