Abstract

This study was performed to investigate responses to the autonomic nerve system and the central nervous system as the thermal comfort conditions based on the PMV (predicted mean vote). To do this, conditions were divided into the comfortable and uncomfortable condition as the PMV value. In addition, EDA (electrodermal activity), ECG (electrocardiogram), and EEG (electroencephalogram) were measured while subjects have performed the task that is required cognitive processing. As a result, the measurements were consistently higher on the uncomfortable condition than on the comfortable condition in the autonomic nervous system. However, in the central nervous system, the orientation of the measurements was different. These results suggested that in the classification and rating of the PMV-based thermal comfort, the periphery physiological measurements which are not related to cognitive function could be used well, whereas the central physiological measurements which are related to cognitive function might not be appropriate.

본 연구는 예상 온열감 반응(predicted mean vote; PMV)에 기반한 쾌적감에 따른 자율신경계 및 중추신경계 반응을 살펴보고자 수행되었다. 이를 위해 PMV에 따라 쾌적 조건과 불쾌 조건을 구분하고 실험참여자가 각 조건에서 인지적 처리과제를 수행하는 동안 자율신경계 반응인 피부 전기활동(electrodermal activity; EDA)과 심전도(electrocardiogram; ECG), 그리고 중추신경계 반응인 뇌전도(electroencephalogram; EEG)를 측정하였다. 그 결과, 자율신경계 반응의 경우, 쾌적 조건에 비해 불쾌 조건에서 보다 각성적인 생리반응이 일관성 있게 관찰되었지만 중추신경계 반응에서는 각 측정부위에서 일관성 있는 결과가 나타나지 않았다. 이러한 결과는 인간의 인지적 기능과 관련이 없는 말초신경계 생리반응의 경우에는 PMV에 의한 쾌, 불쾌의 구분 및 평가가 유효할 수 있지만 인지적 기능과 관련성이 높은 중추신경계 생리반응의 경우에는 PMV에 의한 쾌, 불쾌의 구분 및 평가가 유효하지 않을 수 있음을 의미한다.
