단기 열 경험에 따른 재실자 온열 쾌적감의 시각별 변화 특성 분석

초록

This study aims to identify changes in thermal sensation when the indoor thermal environment suddenly changes after a short-term thermal experience. To understand the thermal adaptation process, it is examined on a time scale of minutes. This study focused on the mechanisms of thermal adaptation changes to hot thermal sensations. The experiment was conducted with two scenarios targeting 13 participants (Scenario 1. From comfortable to uncomfortable hot, Scenario 2. From uncomfortable cold to uncomfortable hot). At the same time as performing the experiment, thermal sensation vote (TSV) and comfort sensation vote (CSV) were surveyed using the right-here-right-now method. Depending on the difference in the previous thermal experience, TSV and CSV were affected from immediately after the change in the indoor thermal environment to 6 minutes. It showed a gradual change and reached a steady-state 15 minutes. Predicted mean vote (PMV), an objective evaluation index, and TSV, a subjective evaluation index, showed a difference immediately after the change in the indoor thermal environment. In order to closely control the indoor thermal environment, it is believed that the thermal experience and thermal adaptation aspects of occupants should be reflected.
