INFLUENCE OF HIGH HUMIDITY ON DISCOMFORT SENSATION UNDER CONDITIONS SLIGHTLY INCLINED TO HOT SIDE FROM THERMAL NEUTRALITY

Abstract

To clarify whether the discomfort caused under high humidity conditions is caused by the humidness/wetness sensations without strong heat/warm sensations, the subject experiments were conducted. As the results, around thermal neutrality on hot/warm side (0 to +0.5 in PMV scale), the discomfort sensation tended to become more intense as the air humidity became higher, and the humidness/wetness sensations might contribute to the discomfort sensation as well as heat/warm sensation. It was suggested that the discomfort sensation vote correlated with skin wettedness as well as PMV, SET* under the conditions in this study.
