jaue2023046: Study on Thermal Sensation Under the Asymmetric Thermal Environment

Abstract

Local heating has a wide range of applications in winter heating, but the asymmetric thermal environment brought by local heating may affect the comfort of residents. Four types of local radiant heating were tested on 24 volunteers in Kitakyushu, Japan. By measuring the asymmetrical skin temperature difference caused by radiant local heating, combined with the subjective evaluation of thermal comfort, the results showed that the most obvious skin temperature difference appeared between the left and right thighs after 30 minutes of heating, exceeding 5°C, and higher radiation intensity may produce poor thermal sensation vote. With the change of radiation intensity and radiation distance, TSV and skin temperature difference change significantly, especially in small rooms.
